Have the function ThreeFiveMultiples(num) return the sum of all the multiples of 3 and 5 that are below num.
For example: if num is 10, the multiples of 3 and 5 that are below 10 are 3, 5, 6, and 9, and adding them up you get 23, so your program should return 23. The integer being passed will be between 1 and 100.

int ThreeFiveMultiples(int num) {

for (int i = 3; i < num; i++) {
if (i % 3 == 0 || i % 5 == 0) {
sum += i;
}
}
return sum;
