    scanf("%d", &num);

    if(num < 1 || num > 26) {
        printf("Invalid input. Please enter a number between 1 and 26.\n");
        return 1;
    }

    // Convert number to letter using ASCII
    letter = 'A' + num - 1;

    printf("The letter corresponding to the number %d is: %c\n", num, letter);

    return 0;
}
