Answer to Question #306054 in C++ for Magisk

Question

Instructions:

1. Your task is to ask the user for a character input.
2. Then, include the cctype built-in library and call the toupper() function. In case you do not know what this function is, this function has the following definition:
3. Return type - int
4. Name - toupper
5. Parameter - one integer which represents the ASCII of a character
6. Description - returns the ASCII of the uppercase equivalent of the character passed
7. Extra note - even though it's function definition in the C++ Programming Language Documentation is int toupper(int ch), you can just pass a normal char variable instead and this will just be automatically typecasted/converted to its integer equivalent.
8. Once you get the uppercase equivalent, print this out.

Sample:

Enter a small letter: a
Uppercase = A

Enter a small letter: f
Uppercase = F

Answer 1

#include <iostream>
#include <cctype>
using namespace std;

int main() {
    char ch;

    cout << "Enter a small letter: ";
    cin >> ch;
    ch = toupper(ch);
    cout << "Uppercase = " << ch;

    return 0;
}
