UNIVERSITY OF THE PUNJAB AD (2 Years) & BS (4 Years) Degree Program/Second Semester - Fall 2025 Paper: Programming Fundamentals Course Code: CC-112N Roll No. Time: 3 Hrs. Marks: 60 THE ANSWERS MUST BE ATTEMPTED ON THE ANSWER SHEET PROVIDED Q.1. Write the output of the following codes in your answer-sheet. Assume that the codes are free of syntax errors (you may ignore any missing or incorrect library imports). (6x5=30) 1. int x = 5; bool val = (x++ == 5) && (x == 6); cout << val << " " << x; 2. int a = 10, b = 20; bool result = (a > b) ? a : b > 15; cout << result; 3. int x = 0; for (int i = 1; i < 5; i++) { if (i % 2) x += 1; else x -= 1; } cout << x; 4. int x = 3, y = 5; bool result = x & y == 1; cout << result; 5. int x = 0; bool res = (x != 0) || (10 / x > 1); cout << res; 6. int x = 10; int *p = &x; cout << *p + 2; (3x10=30) Q.2. Answer the following questions. 1. Write a recursive function int factorial(int n) to calculate the factorial of a number. Demonstrate the execution of the function from main() by taking user input. 2. Write a function that takes an integer array and returns the count of even and odd numbers in the array. Demonstrate the execution of the function from main() by taking user input. 3. Write a program to take an input n and print all prime numbers up to n.
