C++ Program to Find the Number of Vowels, Consonants, Digits and White Spaces in a String
In this example, we will learn to Find the Number of Vowels, Consonants, Digits and White Spaces in a String.
To understand this example, you should have the knowledge of the following C++ programming topics:
Example 1: Program to calculates the number of vowels, consonants, digits and white-spaces From a C-style string
This program takes a C-style string from the user and calculates the number of vowels, consonants, digits and white-spaces.
#include <iostream>
using namespace std;
int main()
{
char line[150];
int vowels, consonants, digits, spaces;
vowels = consonants = digits = spaces = 0;
cout << "Enter a line of string: ";
cin.getline(line, 150);
for(int i = 0; line[i]!='\0'; ++i)
{
if(line[i]=='a' || line[i]=='e' || line[i]=='i' ||
line[i]=='o' || line[i]=='u' || line[i]=='A' ||
line[i]=='E' || line[i]=='I' || line[i]=='O' ||
line[i]=='U')
{
++vowels;
}
else if((line[i]>='a'&& line[i]<='z') || (line[i]>='A'&& line[i]<='Z'))
{
++consonants;
}
else if(line[i]>='0' && line[i]<='9')
{
++digits;
}
else if (line[i]==' ')
{
++spaces;
}
}
cout << "Vowels: " << vowels << endl;
cout << "Consonants: " << consonants << endl;
cout << "Digits: " << digits << endl;
cout << "White spaces: " << spaces << endl;
return 0;
}Output
Enter a line of string: This is 1 hell of a book. Vowels: 7 Consonants: 10 Digits: 1 White spaces: 6
Example 2: Program to calculates the number of vowels, consonants, digits and white-spaces From a String Object
This program takes a string object from the user and calculates the number of vowels, consonants, digits and white-spaces.
#include <iostream>
using namespace std;
int main()
{
string line;
int vowels, consonants, digits, spaces;
vowels = consonants = digits = spaces = 0;
cout << "Enter a line of string: ";
getline(cin, line);
for(int i = 0; i < line.length(); ++i)
{
if(line[i]=='a' || line[i]=='e' || line[i]=='i' ||
line[i]=='o' || line[i]=='u' || line[i]=='A' ||
line[i]=='E' || line[i]=='I' || line[i]=='O' ||
line[i]=='U')
{
++vowels;
}
else if((line[i]>='a'&& line[i]<='z') || (line[i]>='A'&& line[i]<='Z'))
{
++consonants;
}
else if(line[i]>='0' && line[i]<='9')
{
++digits;
}
else if (line[i]==' ')
{
++spaces;
}
}
cout << "Vowels: " << vowels << endl;
cout << "Consonants: " << consonants << endl;
cout << "Digits: " << digits << endl;
cout << "White spaces: " << spaces << endl;
return 0;
}Output
Enter a line of string: I have 2 C++ programming books. Vowels: 8 Consonants: 14 Digits: 1 White spaces: 5

We hope that this Example helped you develop better understanding of the concept of "Count Number of Vowels, Consonants & so on" in C++.
Keep Learning : )
