Satisfied Checker Program

Description

This C program checks a single character provided as a command-line argument. If the character is 'Y', it prints "satisfied". Otherwise, it prints "not satisfied".

Compilation

To compile the program, use a C compiler like GCC:

gcc code.c -o code_executable

Usage

Run the compiled program with a single character argument:

./code_executable <character>

Examples:

1. Input 'Y':

   ./code_executable Y

   Output:

   satisfied
   

2. Input any other character (e.g., 'N'):

   ./code_executable N

   Output:

   not satisfied
   

3. Incorrect number of arguments (none or too many):

   ./code_executable

   or

   ./code_executable A B

   Output:

   Usage: ./code_executable <character>
   

Input

The program expects exactly one command-line argument. Only the first character of this argument is processed.

Output

• If the input character is 'Y', the program prints satisfied followed by a newline.
• If the input character is not 'Y', the program prints not satisfied followed by a newline.
• If the program is run with an incorrect number of command-line arguments, it prints a usage message: Usage: ./<program_name> <character> followed by a newline, and exits with a status code of 1.

Source Code

The source code is located in code.c.

#include <stdio.h>

int main(int argc, char *argv[]) {
    if (argc != 2) {
        printf("Usage: %s <character>\n", argv[0]);
        return 1; // Indicate an error
    }
    char c = argv[1][0]; // Get the first character of the first argument
    if (c == 'Y') {
        printf("satisfied\n");
    } else {
        printf("not satisfied\n");
    }
    return 0;
}
