In this article, we will discuss the concept of C++ program: Check whether the given character is upper or lower case or not
In this post, we are going to learn how to write a program to check whether given character is Upper case or lower case or not using if else in C++ language
In this code, we are going to learn how to check the given character is Upper case or lower case or not using if else statements in C++ language
Program 1
#include <iostream> #include <conio.h> using namespace std; int main() { char ch;//declare character variable cout<<"Enter a character: "; //Ask input from the user cin>>ch;//reading the input if(ch>='A' && ch<='Z'){//check upper case letter cout<<ch<<" is an upper case letter "; } else if(ch>='a' && ch<='z'){//check lower case letter cout<<ch<<" is a lower case letter "; } else{//Display if it is not in Alphabets cout<<ch<<" is not an Alphabets "; } getch(); return 0; }
When the above code is executed, it produces the following result
Case 1
Enter a character: n n is a lower case letter
Case 2
Enter a character: C C is an upper case letter
Case 3
Enter a character: * * is not an Alphabet
In this code, we are going to learn how to check the given character is Upper case or lower case or not using Ascii value in C++ language
Program 2
#include <iostream> #include <conio.h> using namespace std; int main() { char ch;//declare character variable cout<<"Enter a character: "; //Ask input from the user cin>>ch;//reading the input if(ch>=65 && ch<=90){//check upper case letter cout<<ch<<" is an upper case letter "; } else if(ch>=97 && ch<=122){//check lower case letter cout<<ch<<" is a lower case letter "; } else{//Display if it is not in Alphabets cout<<ch<<" is not an Alphabets "; } getch(); return 0; }
When the above code is executed, it produces the following result
Case 1
Enter a character: A A is an upper case letter
Case 2
Enter a character: n n is an lower case letter
Case 3
Enter a character: * * is not an Alphabet
