Program:

#include <iostream>
#include<string.h>
using namespace std;
int main()
{
int count=0;// Here initailizing the value of count
string word;// Here declaring the string variable called word
cout<<"Enter any Word : "; // Here asking the user to Enter any word
cin >> word;// Here scanning the user input
for(int i=0;i<word.length(); i++) // Loop Iteration
{
string ch = word.substr(i,1); // Here taking the sub string called ch from the word string
if (ch == "a" || ch == "e" || ch == "i" || ch == "o" || ch == "u")
count=count+1; // If any of above condition is True then value of count=count+1
}
cout << "Vowels: " << count << endl;// Here printing the value of count
return 0;
}
