Given a string, write a program to count the occurrence of Lowercase characters, Uppercase characters, Special characters, and Numeric values.
Examples:
Input : #GeeKs01fOr@gEEks07 Output : Upper case letters : 5 Lower case letters : 8 Numbers : 4 Special Characters : 2 Input : *GeEkS4GeEkS* Output : Upper case letters : 6 Lower case letters : 4 Numbers : 1 Special Characters : 2
Approach :
- Scan string str from 0 to length-1.
- check one character at a time based on ASCII values
- if(str[i] >= 65 and str[i] <=90), then it is uppercase letter,
- if(str[i] >= 97 and str[i] <=122), then it is lowercase letter,
- if(str[i] >= 48 and str[i] <=57), then it is number,
- else it is a special character
- if(str[i] >= 65 and str[i] <=90), then it is uppercase letter,
- Print all the counters
Implementation:
C++
// C++ program to count the uppercase, // lowercase, special characters // and numeric values #include<iostream> using namespace std; // Function to count uppercase, lowercase, // special characters and numbers void Count(string str) { int upper = 0, lower = 0, number = 0, special = 0; for ( int i = 0; i < str.length(); i++) { if (str[i] >= 'A' && str[i] <= 'Z' ) upper++; else if (str[i] >= 'a' && str[i] <= 'z' ) lower++; else if (str[i]>= '0' && str[i]<= '9' ) number++; else special++; } cout << "Upper case letters: " << upper << endl; cout << "Lower case letters : " << lower << endl; cout << "Number : " << number << endl; cout << "Special characters : " << special << endl; } // Driver function int main() { string str = "#GeeKs01fOr@gEEks07" ; Count(str); return 0; } |
Java
// Java program to count the uppercase, // lowercase, special characters // and numeric values import java.io.*; class Count { public static void main(String args[]) { String str = "#GeeKs01fOr@gEEks07" ; int upper = 0 , lower = 0 , number = 0 , special = 0 ; for ( int i = 0 ; i < str.length(); i++) { char ch = str.charAt(i); if (ch >= 'A' && ch <= 'Z' ) upper++; else if (ch >= 'a' && ch <= 'z' ) lower++; else if (ch >= '0' && ch <= '9' ) number++; else special++; } System.out.println( "Lower case letters : " + lower); System.out.println( "Upper case letters : " + upper); System.out.println( "Number : " + number); System.out.println( "Special characters : " + special); } } |

Upper case letters: 5 Lower case letters : 8 Number : 4 Special characters : 2
Time Complexity: O(N), where N is the string length
Auxiliary Space: O(1)
