text: /*Exercise 3 - Repetition
  
  Write a C program to calculate the sum of the numbers from 1 to n.
  Where n is a keyboard input.
  
  e.g.
  
  n -> 100
  sum = 1+2+3+....+ 99+100 = 5050
  
  n -> 1-
  sum = 1+2+3+...+10 = 55 */
  
  #include <stdio.h>
  int main() {
  
    int n,sum,counter;
  
    printf("Enter a number: ");
    scanf("%d",&n);
  
    while(counter<=n){
      counter=1;
      sum=0;
      sum=sum+counter;
      ++counter;
    }
    printf("Sum is %d",sum);
    
    return 0;
  }
