C++ Program To Convert Character Cases

Write C Program to convert a character from upper to lower and lower to upper case

// Write C program to convert case of entered character

#include<iostream>

using namespace std;

int main()
{
    char upper, lower; // declare variables
    int ascii;

    // convert in lower case

    cout << "Enter the Upper Case Character :--> ";
    cin >> upper;

    ascii = upper + 32;

    cout << "Lower case of " <<upper <<" : " << char(ascii);

    // convert in upper case

    cout << "\n\nEnter the Lower Case Character :--> " ;
    cin >> lower;

    ascii = lower - 32;

    cout << "Upper case of " <<  lower << " : " << char(ascii);

    return 0;
