SULIT Question 3 (C3, CO1, PO1) a) Trace the output of the following program segment: int ptr, q; q = 50; ptr = &q; printf("%d", ptr); b) Write the function definition for function swap, to swap two numbers. #include <stdio.h> void swap (int n1, int n2); //function prototype int main() { int num1 = 5, num2 = 10; swap(&num1, &num2); //function call printf("num1 = %d\n", num1); printf("num2 = %d\n", num2); return 0; } //function definition for function "swap" ... c) Write a function definition that accepts a string as an input and then prints the characters in the string in a reverse order. Example, the input string "UniMAP" will be displayed as "PAMinU". (Hint: You could use the strlen () function to find the string length.) (EKT 150) (2 Marks) (4 Marks) (6 Marks)

Question 3
(C3, CO1, PO1)
a) Trace the output of the following program segment:
int *ptr, q;
q = 50;
ptr = &q;
printf("%d", *ptr);
b) Write the function definition for function swap, to swap two numbers.
#include <stdio.h>
void swap (int *n1, int *n2);
//function prototype
int main()
{
int num1 = 5, num2 = 10;
swap(&num1, &num2);
//function call
printf("num1 = %d\n", num1);
printf("num2 = %d\n", num2);
return 0;
}
//function definition for function "swap"
...
c) Write a function definition that accepts a string as an input and then prints the characters in the
string in a reverse order. Example, the input string "UniMAP" will be displayed as "PAMinU".
