Problem 4 Consider the following program: #include using namespace std; int(int a, int&b, char &e) { 1. int result; 2. if (c = 'a') { 3. a=a+++b): 4. result-b; 5. else if (c='5') 6. b=b*a++); 7. result - a - b; 8. else 9.C="?': 10. result = --b; 12. > return result: void main() { 13. int x = 2, y -4,7 14. char ca = 'a': 15. z=f(x, y, ca); 16. cout using namespace std; int(int a, int&b, char &e) { 1. int result; 2. if (c = 'a') { 3. a=a+++b): 4. result-b; 5. else if (c='5') 6. b=b*a++); 7. result - a - b; 8. else 9.C="?': 10. result = --b; 12. > return result: void main() { 13. int x = 2, y -4,7 14. char ca = 'a': 15. z=f(x, y, ca); 16. cout
