Explanation:

• #include <stdio.h>: Includes the standard input-output library for basic input and output operations.

• int main() { }: The main function where the program execution starts.

• char c;: Declares a variable c of type char to store a single character.

• printf("Enter a character: ");: Displays a message prompting the user to enter a character.

• c = getchar();: Uses getchar() to read a single character from the standard input (keyboard) and assigns it to the variable c.

• printf("You entered: ");: Displays a message indicating what the user entered.

• putchar(c);: Outputs the character stored in the variable c to the standard output (console).

• return 0;: Indicates successful completion of the main() function and the program terminates with a status code of 0.
