To make a switch case for keyboard input in C++, you can use the switch statement along with the cin function to read the keyboard input. Here's an example:

#include <iostream>
using namespace std;

int main() {
    char choice;

    cout << "Enter your choice (A, B, C, D): ";
    cin >> choice;

    switch(choice) {
        case 'A':
            cout << "Option A selected." << endl;
            break;
        case 'B':
            cout << "Option B selected." << endl;
            break;
        case 'C':
            cout << "Option C selected." << endl;
            break;
        case 'D':
            cout << "Option D selected." << endl;
            break;
        default:
            cout << "Invalid choice." << endl;
    }

    return 0;
}


In this example, the user is prompted to enter a character and the input is stored in the choice variable. The switch statement is then used to check the value of choice against different cases. Depending on the input, the corresponding block of code will be executed. If none of the cases match, the default block is executed.

This code snippet demonstrates how you can create a switch case using keyboard input in C++. It prompts the user to enter a character ('A', 'B', 'C', or 'D'), reads the input using cin, and then utilizes a switch statement to execute the relevant case based on the user's input. Lastly, it has a default case to handle situations where the input does not match any of the predefined cases.
