What will be the output of the following program?
#include <stdio.h>#include <string.h>int main(){ char str[] = "san foundry"; int len = strlen(str); int i; for(i = 0; i < len; i++) push(str[i]); // pushes each character into stack for(i = 0; i < len; i++) printf("%c", pop()); // pops and prints from stack}
Options
- A. yrdnuof nas
- B. foundry nas
- C. sanfoundry
- D. san foundry
Correct Answer (Detailed Explanation is Below)
A. yrdnuof nas
Detailed Explanation
Step 1: Push all characters into stack
Stack (top at right):
s a n f o u n d r y
Step 2: Pop all characters from stack
Stack follows LIFO (Last In First Out)
So popping will reverse the string.
Reversed string:
yrdnuof nas
