### LANGUAGE: C++

### CHALLENGE:

Given int variables k and total that have already been declared, use a do…while loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. Thus your code should put 1*1 + 2*2 + 3*3 +… + 49*49 + 50*50 into total. Use no variables other than k and total.

### SOLUTION:

total=0; k=1; do{ total += k*k; k++; }while (k<=50);

It specifically says to use a for loop…

total = 0;

for (k=1; k<=50; k++){

total += k*k;

}

HERE IS THE C CODE:

k = 1;

total = 0;

while (k<=50)

{

total += (k*k);

k++;

}

for the for loop

total = 0;

for (k =1; k <= 50; k++){

total += k*k;

}

what would be the answer for visual basics
