Examples

Unbeautified:

      
#include <stdio.h>

int main()
{
int n, count, sum = 0;

printf("Enter the value of n(positive integer): ");
scanf("%d",&n);

for(count=1; count <= n; count++){sum = sum + count;}

printf("Sum of first %d natural numbers is: %d",n, sum);

return 0;
}
      
    

After beautified:

      
#include <stdio.h>

int main() {
  int n, count, sum = 0;

  printf("Enter the value of n(positive integer): ");
  scanf("%d", &n);

  for (count = 1; count <= n; count++) {
    sum = sum + count;
  }

  printf("Sum of first %d natural numbers is: %d", n, sum);

  return 0;
}
