C++

How do I use ASC II in order to see if an alphabet is lowercase or uppercase?

Please show me how to do this.

Answer 1

#include <iostream>

using namespace std;

int main() {
    char ch;
    cout << "Enter a single character: ";
    cin >> ch;

    if (ch >= 'a' && ch <= 'z') {   // we can simply compare with 'a' and 'z' see if character is in the range of lowercase
        cout << ch << " is lowercase" << endl;
    } else if (ch >= 'A' && ch <= 'Z') {   // we can simply compare with 'A' and 'Z' see if character is in the range of uppercase
        cout << ch << " is uppercase" << endl;
    } else {
        cout << ch << " is neither lowercase not uppercase" << endl;
    }
    return 0;
}
