C++ Program to Convert Uppercase to Lowercase

C++ Program to Convert Uppercase to Lowercase

To convert a character from uppercase to lowercase in C++ programming, you have to ask to the user to enter a character in uppercase to convert it into lowercase and display the equivalent character in lowercase.

To change uppercase character into lowercase character, just add 32 in character in uppercase to convert it into lowercase. Since ASCII value of A is 65 and ASCII value of a is 97.

So, 65+32 = 97 = a = equivalent value of A in lowercase i.e., a.

To understand below example, you have must knowledge of following C++ programming topics; Cout in C++ and Cin in C++

#include<iostream.h>
#include<conio.h>

void main()
{
	clrscr();
	char ch;
	cout<<"Enter a Character in Uppercase: ";
	cin>>ch;
	ch=ch+32;
	cout<<"Character in Lowercase: "<<ch;
	getch();
}

Enter a Character in Uppercase: B
Character in Lowercase: b
