Introduction

I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.

#include <iostream>
 
using namespace std;
 
int main(){
 
    char gender;
 
    //Reading gender from user
    cout<<"Enter gender (M/m or F/f): ";
    cin>>gender;
 
    switch(gender)
    {
        case 'M':
        case 'm':
            cout<<"Male";
            break;
        case 'F':
        case 'f':
             cout<<"Female";
            break;
        default:
             cout<<"Unspecified Gender"<<endl;
    }
 
    return 0;
 
}

Result
