Program to count vowels, consonant, digits and special characters in string.
Given a string and the task is to count vowels, consonant, digits and special character in string. Special character also contains the white space.
Examples:
Input : str = "geeks for geeks121"
Output : Vowels: 5
Consonant: 8
Digit: 3
Special Character: 2
Input : str = " A1 B@ d adc"
Output : Vowels: 2
Consonant: 4
Digit: 1
Special Character: 6
C++
#include <bits/stdc++.h>
using namespace std;
void countCharacterType(string str)
{
int vowels = 0, consonant = 0, specialChar = 0,
digit = 0;
for ( int i = 0; i < str.length(); i++) {
char ch = str[i];
if ( (ch >= 'a' && ch <= 'z' ) ||
(ch >= 'A' && ch <= 'Z' ) ) {
ch = tolower (ch);
if (ch == 'a' || ch == 'e' || ch == 'i' ||
ch == 'o' || ch == 'u' )
vowels++;
else
consonant++;
}
else if (ch >= '0' && ch <= '9' )
digit++;
else
specialChar++;
}
cout << "Vowels: " << vowels << endl;
cout << "Consonant: " << consonant << endl;
cout << "Digit: " << digit << endl;
cout << "Special Character: " << specialChar << endl;
}
int main()

countCharacterType(str);
return 0;
