Answer 1

#include<iostream>
using namespace std;

void Pancake(int x, int& y, int z);
void Waffle(int& x, int& y);
int Doughnut(int y, int z);

int main( )
{
int a = 1;
int b = 2;
int c = 3;
int d = 4;

Pancake(a, b, c);//a = 1 ,b = 2+3 = 5 ,c = 3
Waffle(b, c); //value of b and c swapped b = 3 ,c=5
Pancake(d, c, b); //d=4 , c = c+3 = 5+3 =8 , b = 3
d = Doughnut(b, a); //d=5
return 0;
}

void Pancake(int x, int& y, int z)
{
y += 3;
z = x + y;
}

void Waffle(int& x,int& y)
{
int temp;
temp = x;
x = y;
y = temp;
}

int Doughnut(int y, int z)
{
int w;
w = y * 2; //w = 3*2 = 6
z = w + 3; //z = 6+3 = 9
w --; //w = 6-1 = 5
return w; //return 5
}
(62)The values of d after the call to function Waffle = 4
(63)The values of a after the second call to function Pancake = 1
(64)The values of b after the second call to function Pancake = 3
(65)The values of c after the second call to function Pancake = 8
