GETCHAR()

this is is used to read a single character from the standard input. it waits for the user to enter a character and returns that character as an int. If an end-of-file (EOF) is encountered, it returns EOF. it is commonly used in situations where you want to read one character at a time.

#include <stdio.h>

int main() {
    char ch;

    // Read a character from the user
    printf("Enter a character: ");
    ch = getchar();  // Read one character 
                     // Give Input As a

    // Output the character using putchar
    printf("You entered: ");
    putchar(ch);  // Output the entered character

    return 0;
}
