c check if character is upper case

Certainly! Here's a C code snippet to check if a character is uppercase:

#include <stdio.h>

int main() {
    char ch;

    printf("Enter a character: ");
    scanf("%c", &ch);

    if (ch >= 'A' && ch <= 'Z') {
        printf("The character is uppercase.\n");
    } else {
        printf("The character is not uppercase.\n");
    }

    return 0;
}

Explanation: - The code begins by including the necessary header file <stdio.h> to enable input/output operations. - In the main() function, a variable ch of type char is declared to store the input character. - The printf() function prompts the user to enter a character. - scanf() is used to take the user input and store it in the variable ch. - The if statement checks whether the entered character (ch) falls within the ASCII range of uppercase letters. The condition ch >= 'A' && ch <= 'Z' checks if the character is between 'A' and 'Z' inclusive. - If the condition is true, it prints that the character is uppercase; otherwise, it indicates that the character is not uppercase.
