Need help with these study question

1. Here is the prototype for a function named computeValue:

void computeValue(int);

Which of the following is a correct call (invoke) to this function?

computeValue(10)

computeValue(10);

void computeValue(10);

void computeValue(int x);

2.

What is the output from the following piece of code?

#include using namespace std; void copy (int& a, int& b, int& c); int main () { int x = 5, y = 3, z = 7; copy (x, y, z); cout << x << " & " << y << " & " << z; return 0; } void copy (int& a, int& b, int& c) { a *= 2; b *= 2; c *= 2; }

3.

What is the output from the following piece of code?

#include using namespace std; void copy (int& a, int b, int& c); int main () { int x = 5, y = 3, z = 7; copy (x, y, z); cout << x << " & " << y << " & " << z; return 0; } void copy (int& a, int b, int& c) { a *= 2; b *= 2; c *= 2; }

4.A function can have zero to many parameters, and it can return this many values:

zero to many

none

no more than one

maximum of ten
