Determine whether the following program segments contain errors. For each error, explain how it can be corrected. [Note: For a particular program segment, it’s possible that no errors are present.]

Question

```
a)
template
int sum(int num1, int num2, int num3) {
return num1 + num2 + num3;
}
b)
void printResults(int x, int y) {
cout << "The sum is " << x + y << '\n';
return x + y;
}
c)
template
A product(A num1, A num2, A num3) {
return num1 * num2 * num3;
}
d) double cube(int);
int cube(int);
