tolower()
Prototype: int tolower(int chr);
Header File: ctype.h (C) or cctype (C++)
Explanation: Tolower will return the ASCII value for the lowercase equivalent
of the ASCII character chr, if it is a letter. If the character is already
lowercase, it remains lowercase
//Example reads in a character and makes up lowercase
#include <iostream>
#include <cctype>
using namespace std;
int main()
{
char x;
cin>>x;
x=tolower(x);
cout<<x;
}
