Question

C++.

Write a function ComputeVal that takes two integer parameters and returns the product of the two parameters minus 8.

Ex: ComputeVal(5, 9) returns 37.

Code:

#include <iostream>

using namespace std;

/* Your code goes here */

int main() {

int input1, input2;

int result;

cin >> input1;

cin >> input2;

result = ComputeVal(input1, input2);

cout << result << endl;

return 0;

}

Answer 1

int ComputeValue(int value1, int value2)

{

return (value1 * value2) - 8;

}

You are assuming that this function returns an int, but the product of the two values can get quite big. The result may not fit into an int variable. If the values can exceed the limits of int, it might be better to change the return value to a 64 bit value.

long long ComputeValue(int value1, int value2)

{

return ((long long)value1 * value2) - 8;

}
