C++ Program to check whether a character is uppercase, lowercase ,digit or special character
Character is uppercase ,lowercase ,digit or special character
Here we will discuss C++ program to check whether a character is uppercase, lowercase ,digit or special character. As there are different types of character in C++, so we’ll learn to write a code to do so.
Program to check whether a character is uppercase, lowercase ,digit or special character
In C++ programming language a char type variable can store many different types of values ,128 values in total, single value at a time. Each value has been assigned a code by which they can be identified and that is called ASCII code.
- Alphabets
- Uppercase( between 65 to 90 )
- Lowercase( between 97 to 122)
- Digits (between 48 to 57)
- Special Characters (all the remaining in between 0 to 127)
Working:
- User gives an input.
- The input is stored in a char type variable say prep.
- prep is then checked using the if else-if statement.
- For uppercase alphabets
if((prep >= 65) && (prep <= 90))
- For lowercase alphabets
else if((prep >= 97) && (prep <= 122))
- For digits
else if((prep >= 48) && (prep <= 57))
- All others will be the special characters.
C++ code
Run
//C++ program
//Character is alphabet, a digit, or a special character
#include <iostream>
using namespace std;
int main()
{
char charCheck;
cout<<"Enter a character: "; cin>>charCheck;
//for uppercase alphabets
if((charCheck >= 65) && (charCheck <= 90))
{
cout<<charCheck<<" is Uppercase Alphabet"; } // for lowercase alphabets else if((charCheck >= 97) && (charCheck <= 122))
{
cout<<charCheck<<" is Lowercase Alphabet"; } //for digits else if((charCheck >= 48) && (charCheck <= 57))
{
cout<<charCheck<<" is a Digit";
}
//all remaining are special characters
else
{
cout<<charCheck<<" is a Special Character";
}
return 0;
}
Output:
Enter a character: @ @ is a Special Character
