C Program to Print 1 to 100 using For and While Loop

Write a program to print 1 to 100 number using for and while loop.

C Program to Print 1 to 100 using For Loop

For loop syntax.

1. Declare variable i .

2. Using for loop specify initialize, condition and update statement .

  for(initialize; condition; update statement) {
        code;
   }

  for (i=1; i<=100; i++){

        printf("%d ",i);

  } 

Program

#include <stdio.h>
int main(){

    /* Declare variable i. */
    
    int i;
   
    for(i=1 ; i<=100; i++){
     
        /* Print the value of i. */

     printf("%d ",i);
    } 
   
   return 0;
}

C Program to Print 1 to 100 using While Loop

#include <stdio.h>

int main(){

    /* Declare and initialize variable i. */
    
    int i=1;
   
    /* Specify condition i is less than or equal to 100. */
    while(i<=100){
     
     printf("%d ",i);
     
        /* Increment the value of i. */

     i++;
    } 
   
   return 0;
}

Output:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
