C programs with output showing usage of operators, loops, functions, arrays, performing operations on strings, files, pointers. Download executable files and execute them without compiling the source file. Code::Blocks IDE is used to write programs, most of these will work with GCC and Dev C++ compilers. The first program, prints 'Hello World.'

If you are using your own computer, you can save the program wherever you want; however, you should consider creating a folder to hold all of your C.S.1318 programming assignments. If you are using a shared lab machine, you are only able to save your program in the My Documents folder. Before logging off the lab machine, be sure that you have. The latest program version came out in 2015, so it’s pretty dated by programming standards. DEV-C for Windows contains all standard features necessary for creating, fixing, and executing programs written in C program languages. As C is an object-oriented expansion of C, it also supports earlier versions of the language. I've just installed Dev-C 5.11 on Windows 7 64 bits. I can compile and execute the program just fine. I can add a watchpoint and go step by step, BUT if I add a Watch to see a variable, the debug freezes. Tag: c,dev-c. I wrote a program to sum all odd numbers less than or equal to N. It's not the most efficient or eloquent program, but it works in the compiler on Codepad.org and does not work in DevC. Usually when a program I wrote is stuck in some kind of infinite loop the program crashes in DevC and Windows stops it and lets me know. Nov 10, 2016  DEV-C for Windows contains all standard features necessary for creating, fixing, and executing programs written in C program languages. As C is an object-oriented expansion of C, it also supports earlier versions of the language. It allows an aspiring programmer to compose all source code within the IDE without simple features standard for more beginner-friendly programs. For instance.

C programming examples with output

Example 1 - C hello world program
/** My first C program */

Output of program:
'Hello World'

Example 2 - C program to get input from a user using scanf

int main()
{
int x;

printf('Input an integern');
scanf('%d',&x);// %d is used for an integer

printf('The integer is: %dn', x);

return0;
}

Output:
Input an integer
7897
The integer is: 7897

Example 3 - using if else control instructions

int main()
{
int n;

printf('Enter a numbern');
scanf('%d',&n);

if(n >0)
printf('Greater than zero.n');
else
printf('Less than or equal to zero.n');

return0;
}

Output:
Enter a number
-45
Less than or equal to zero.

Example 4 - while loop example

Output:
1 2 3 4 5 6 7 8 9 10

Example 5 - C program check if an integer is prime or not

Example 6 - command line arguments

int main(int argc,char*argv[])
{
int c;

printf('Number of command line arguments passed: %dn', argc);

for(c =0; c < argc; c++)
printf('%d argument is %sn', c +1, argv[c]);

return0;
}

This program prints the number of arguments and their contents.

Example 7 - Array program

int main()
{
int array[100], n, c;
printf('Enter number of elements in arrayn');
scanf('%d',&n);
printf('Enter %d elementsn', n);
for(c =0; c < n; c++)
scanf('%d',&array[c]);
printf('The array elements are:n');
for(c =0; c < n; c++)
printf('%dn', array[c]);
return0;
}

Example 8 - function program

void my_function();// Declaring a function

int main()
{
printf('Main function.n');

my_function();// Calling the function

printf('Back in function main.n');

return0;
}

// Defining the function
void my_function()
{
printf('Welcome to my function. Feel at home.n');
}

Example 9 - Using comments in a program

Example 10 - using structures in C programming

How To Run C Program In Dev C++

struct game
{
char game_name[50];
int number_of_players;
};// Note the semicolon

int main()
{
struct game g;

strcpy(g.game_name,'Cricket');
g.number_of_players=11;

printf('Name of game: %sn', g.game_name);
printf('Number of players: %dn', g.number_of_players);

return0;
}

Example 11 - C program for Fibonacci series

int main()
{
int n, first =0, second =1, next, c;

printf('Enter the number of termsn');
scanf('%d',&n);

printf('First %d terms of Fibonacci series are:n', n);

for(c =0; c < n; c++)
{
if(c <=1)
next = c;
else
{
next = first + second;
first = second;
second = next;
}
printf('%dn', next);
}

return0;
}

Example 12 - C graphics programming

int main()
{
int gd = DETECT, gm;
initgraph(&gd,&gm,'C:TCBGI');
outtextxy(10,20,'Graphics programming is fun!');
circle(200,200,50);
setcolor(BLUE);
line(350,250,450,50);
getch();
closegraph();
return0;
}

How to compile C programs with GCC compiler?

If you are using GCC on Linux operating system, then you may need to modify the programs. For example, consider the following program that prints the first ten natural numbers.

int main()
{
int c;

for(c =1; c <=10; c++)
printf('%dn', c);
getch();
return0;
}

The program includes a header file <conio.h> and uses function getch, but this file is Borland specific, so it works in Turbo C compiler but not in GCC. The program for GCC must be like:

int main()
{
int c;

/* for loop */

for(c =1; c <=10; c++)
printf('%dn', c);
return0;
}

If you are using GCC, save the program in a file say 'numbers.c' to compile the program, open the terminal and enter the command 'gcc numbers.c', this compile the program and to execute it enter the command './a.out' do not use quotes while executing commands. You can specify the output file name as 'gcc numbers.c -o numbers.out', to run execute './numbers.out' in the terminal.

C programming tutorial

A program consists of functions that contain instructions given to a machine to perform a task. The process of writing it includes designing an algorithm, drawing a flowchart, and then writing code. After writing it, you need to test it and debug it if it does not produce the required output.

To write a program, you need a text editor (use your favorite one) and a compiler. A compiler converts source code into machine code, which consists of zero's and one's only, ready to be executed on a machine.

An IDE (Integrated Development Environment) provides a text editor, compiler, debugger, etc. for developing programs and managing projects. Code::Blocks IDE provides an ideal environment for development. It can import Microsoft Visual C++ projects, is extendable as it uses plug-ins, open-source, and cross-platform.

How to write a C program?

A program must have at least one function which must be main. A function consists of declarations and statements. A statement is an expression followed by a semicolon. For example, a + b, printf('C program examples') are expressions and a + b; and printf('C is an easy to learn computer programming language'); are statements.

Compile C Program In Dev C++

To use a variable, we must indicate its type, whether it is an integer, float, character, or others. C language has many built-in data types, and we can create our own using structures and unions. Every data type has its size that may depend on the machine; for example, an integer may be of 2 or 4 Bytes. Data is stored in a binary form, i.e., a group of bits where each bit can be '0' or '1'.

Keywords such as 'switch,' 'case,' 'default,' 'register,' are reserved words with predefined meaning and can't be used as the name of a variable or a function. Memory can be allocated at compile-time or run-time using malloc and calloc functions. C language has many features such as recursion, preprocessor, conditional compilation, portability, pointers, multi-threading by using external libraries, dynamic memory allocation. Thanks to these, it is used for making portable software programs and applications. Using networking API's users can communicate and interact with each other and share files.

C standard library contains functions for mathematical operations, characters, input/output, files, and many more. The process of making a program which is known as coding requires knowledge of programming language and logic to achieve the desired output. So you should learn C programming basics and start making programs.

Learning data structures (stacks, queues, linked lists) using C provides you a greater understanding as you learn everything in detail. A general belief is to go for high-level languages. However, it's a good idea to learn C before learning C++ or Java. C++ is object-oriented and contains all features of C, so learning C help you learn C++ quickly, then you can study Java.
