1.	C program to find sum of squares of n natural numbers using while loop
Answer» ANSWER: #include int main() { int n, i, sum = 0; printf("ENTER a positive INTEGER: "); scanf("%d",&n); i = 1; while ( i <=n ) { sum += i; ++i; } printf("Sum = %d",sum); return 0; } Explanation: the loop is iterated n number of times. And, in each iteration, the value of i is ADDED to sum and i is incremented by 1.

Answer»

#include

int main()

{

int n, i, sum = 0;

printf("ENTER a positive INTEGER: ");

scanf("%d",&n);

i = 1;

while ( i <=n )

{

sum += i;

++i;

}

printf("Sum = %d",sum);

return 0;

}

Explanation:

the loop is iterated n number of times. And, in each iteration, the value of i is ADDED to sum and i is incremented by 1.
