Question: 2. Consider the following program. #include using namespace std void summer(int&, int); void fall(int, int&) int x int main) int intNum1 2; int intNum2 #

2. Consider the following program. #include using namespace std void summer(int&, int); void fall(int, int&) int x int main) int intNum1 2; int intNum2 # 5; x 6 summer(intNum1, intNum2); fall(intNum1, intNum2); return O; void summer(int& a, int b) int intNum1 intNum1 b + 12; a 2 b+5; b = intNum 1 + 4; void fall(int u, int& v) int intNum2 intNum2 X v intNum2 4; Answer the following questions: a. What is the output? Consider variable scope. Considering the function summer, parameter 1 is called by reference. What is passed into the function for parameter 1, i.e., what value does parameter 1 receive? b. 2 is called by value. What occurs in memory for parameter 2 and local variable int intNum1? Hint: consider memory, parameters and local variables c. Again, considering the function summer, parameter
