Given a character, the task is to check whether the given character is in upper case, lower case or non-alphabetic character
Examples:
Input: ch = 'A' Output: A is an UpperCase character Input: ch = 'a' Output: a is an LowerCase character Input: ch = '0' Output: 0 is not an aplhabetic character
Approach: The key to solve this problem lies in the ASCII value of a character. It is the most simple way to find out about a character. This problem is solved with the help of following detail:
- Capital letter Alphabets (A-Z) lie in the range 65-91 of the ASCII value
- Small letter Alphabets (a-z) lie in the range 97-122 of the ASCII value
- Any other ASCII value is a non-alphabetic character.
Implementation:
C++
// C++ implementation of the above approach #include<bits/stdc++.h> using namespace std; void check(char ch) { if (ch >= 'A' && ch <= 'Z') cout<< ch << " is an UpperCase character\n"; else if (ch >= 'a' && ch <= 'z') cout<< ch << " is an LowerCase character\n"; else cout<< ch << " is not an aplhabetic character\n"; } // Driver Code int main() { char ch; // Get the character ch = 'A'; // Check the character check(ch); // Get the character ch = 'a'; // Check the character check(ch); // Get the character ch = '0'; // Check the character check(ch); return 0; } // This code is contributed by Code_Mech |
