Problem Statement

Write a C program to dynamically allocate memory for a character using `malloc`, store a character, print it, and free the memory.

Input Format

A single character.

Output Format

Print the character stored in dynamically allocated memory.

Constraints

Valid ASCII character

Sample Input

K

Sample Output

K

Explanation

Use `malloc(sizeof(char))` to allocate heap memory for a character, dereference to assign and print, then free.

Starter Code

#include <stdio.h>
#include <stdlib.h>

int main() {
    char ch;
    if (scanf(" %c", &ch) == 1) {
        // Write your code here to dynamically allocate character
    }
    return 0;
}

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
