C - Use Incrementing Operator in for Loop statement

Introduction

To add one to a variable's value, use ++, as in:

var++; 

After this statement is executed, the value of variable var is incremented by 1. It's the same as writing this code:

var=var+1; 

You'll find ++ used in for loops; for example:

for(x=0;x<100;x++) 

This looping statement repeats 100 times. It's much cleaner than writing the alternative:

for(x=0;x<100;x=x+1) 

Demo

#include <stdio.h>

int main()/*from   ww  w.  j  a  va 2s  .  c  o  m*/
{
    int x;

    for(x=0;x<10;x++)
        puts("hi!");
    return(0);
}

Result

Use incrementing Operator inside while loop

Demo

#include <stdio.h>

int main()// w ww.  jav a  2s. co  m
{
    int x;

    x=0;
    while(x<10)
    {
        puts("hi!");
        x++;
    }
    return(0);
}
