for Loop

for Loop in C

For loop is a conditional iterative statement which is used to check certain conditions and then repeatedly execute a block of code untill the conditions are satisfied.

Syntax

        
    for(initialization; condition; increment/decrement)
    {
        //Code
    }      
        
    

Let's understand the syntax

• The initialization statement is executed only once.




• Then, the condition is evaluated. If the condition is evaluated to false, the for loop is terminated.




• If the condition is evaluated to true, statements inside the body of the for loop are executed, and the increment/decrement statement is updated.




• Again the condition is evaluated.

This process goes on until the condition is false. When the condition is false, the loop terminates.

Let's write a C program to print numbers 1 to 10.

Program

        
#include <stdio.h>

int main ()
{
    int i;

    for (i = 1; i < 11; ++i)
    {
        printf("%d ", i);
    }
    return 0;
}             
        
    

Output

        
1 2 3 4 5 6 7 8 9 10
