Sum Through while loop:

#include<stdio.h>

#include<conio.h>

int main()

{

    int a,b,sum,totalsum,num=1;

   printf("enter the a\n");

    scanf("%d",&a);

     printf("enter the b\n");

    scanf("%d",&b);

   // printf("the sum is %d\n",sum);

    do

    {

    

    sum=a+b;

    totalsum=totalsum+num;

    num++;}

    while(num<=10);

    printf("sum is %d",totalsum);

    

getch();

}
