Problem Statement

Write a C program that takes an integer N, applies pre-increment (++N), post-increment (N++), and prints the results in sequence.

Input Format

A single integer N.

Output Format

Print three lines: 1) Value after pre-increment, 2) Value captured during post-increment statement, 3) Final value of N.

Constraints

-10000 <= N <= 10000

Sample Input

5

Sample Output

6
6
7

Explanation

++n makes n=6 (prints 6). n++ evaluates to 6 (prints 6) and makes n=7. Final value is 7.

Starter Code

#include <stdio.h>

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        // Write your code here
    }
    return 0;
}

Limits

  • Time Limit: 1s
  • Memory Limit: 256MB

Embedded C Programming

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
