Write a program that tests whether the examples of the math library function calls below actually produce the indicated results.
```
ex06_02.cpp
#include
using namespace std;
int cube(int y); // function prototype
int main() {
int x{0};
for (x = 1; x <= 10; x++) { // loop 10 times
cout << cube(x) << endl; // calculate cube of x and output results
}
}
// definition of function cube
int cube(int y) {
return y * y * y;
}
```
```
// ex06_03.cpp
// Testing the math library functions.
