Determine whether the following program segments contain errors. For each error, explain how to correct it. [Note: It's possible that no errors are present in the segment.]

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);
