Write a program that reads a character and says if it is a letter or not, in case of a letter it says if it is a lowercase or uppercase letter.

******** In Algorithm ********

Algorithm Variables C: character Begin write(" Enter a letter :") read (C) if (C >= 65 and C <=90 ) write (" this letter is uppercase ") else if (C >= 97 and C <= 122 ) write(" this letter is lowercase ") else write (" it's not letter !!!! ") next_if next_if End Result ==> Enter a letter : M this letter is uppercase

******** in C ********

#include <stdio.h> int main(){ char C ; printf(" Enter a letter :"); scanf("%c",&C); if (C >= 65 && C <=90 ) printf(" this letter is uppercase "); else { if (C >= 97 && C <= 122 ) printf(" this letter is lowercase "); else printf("it's not letter !!!! "); } return 0; }

******** in C++ ********

#include <iostream> using namespace std; int main(){ char C ; cout<<" Enter a letter :"; cin>>C; if (C >= 65 && C <=90 ) cout<<" this letter is uppercase "; else { if (C >= 97 && C <= 122 ) cout<<" this letter is lowercase "; else cout<<" it's not letter !!!! "; } return 0; }
