6.7.4.While loop and sum integers

#include <stdio.h>



int main(void)

{

  long sum = 0L;

  int i = 1;    

  int count = 0;



  printf("\nEnter the number of integers you want to sum: ");

  scanf(" %d", &count);



  while(i <= count){

    sum += i++;

  }



  printf("Total of the first %d numbers is %ld\n", count, sum);

  return 0;

}

Enter the number of integers you want to sum: 1
     Total of the first 1 numbers is 1
