Below I have shared C++ program to check whether a given character is an uppercase or lowercase alphabet, a digit or a special character. First of all I read a character an then compare it with ASCII values given below.
Uppercase Alphabet: 65-90
Lowercase Alphabet: 97-122
Digit: 48-57
If ASCII value of character is other then the values mentioned above then it is a special character.
C++ Program to Check Given Character is Uppercase, Lowercase, Digit or Special Character

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
#include<iostream> using namespace std; int main() { char ch; cout<<"Enter any character: "; cin>>ch; if(ch>=65&&ch<=90) cout<<endl<<"You entered an uppercase character"; else if(ch>=48&&ch<=57) cout<<endl<<"You entered a digit"; else if(ch>=97&&ch<=122) cout<<endl<<"You entered a lowercase character"; else cout<<endl<<"You entered a special character"; return 0; } |
Output
Enter any character: F
You entered an uppercase character
I have a question regarding this program.
I tried writing this concept in form of nested if-else statements like the “dangling if-else statement”.
eg:
if(expr 1)
if(expr 2)
statement 1;
else
statement 2;
.
.
.
the program doesn’t work… What’s wrong in this concept?
Please do reply.
Thanks
it does not work properly I have copied your code and run
it shows same msg on every input
msg is that
You entered a digit
What would the statement be if you needed to write a program to check a single letter like if “Q” was upper or lower case?
