Chapter 15, Problem 15.10E

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 < class A >

int sum(int num1, int num2, int num3)

{

return $\text{num}1+\text{num2+num3}$

;

}

b. void printResults (int x, int y)

{

cout « “The sum is” $\ll \text{x}+\text{y}\ll \text{'}/\text{n}\text{'}$ ;

return $\text{x}+\text{y}$

;

}

c. template < A >

A product (A num1, A num2, A num3)

{

return num1 * num2 * num3;

}

double cube (int);

int cube (int);
