LANGUAGE: C++
CHALLENGE:
Write a for loop that computes the following sum : 5+10+15+20+…+485+490+495+500. The sum should be placed in a variable sum that has already been declared and initialized to 0. In addition, there is another variable , num that has also been declared. You must not use any other variables.
SOLUTION:
for(int num=1; num<=500; num++){
if ((num % 5)==0){
sum+=num;
}
}
for (num = 5; num <= 500; num += 5)
{
sum += num;
}
