Zoho - Second round- Reversing the vowels

Given a string, reverse only the vowels present in it and print the resulting string.

Input: First line of the input file contains an integer T denoting the number of test cases. Then T test cases follow. Each test case has a single line containing a string.

Output: Corresponding to each test case, output the string with vowels reversed.

Example:
Input:
practice

Output:
prectica

C++ Program:

#include<iostream>
#include<conio.h>
#include<string.h>

using namespace std;
int main()
{
    string a,b;
    cin >> a;
    int len= a.length();
    int count=0; 
    for(int i=0;i<len;i++)
    {
    if(a[i]=='a'||a[i]=='e'||a[i]=='i'||a[i]=='o'||a[i]=='u')
    {
    b=b+a[i];
    count+=1;
    }
    }
    for(int i=0;i<len;i++)
    {
    if(a[i]=='a'||a[i]=='e'||a[i]=='i'||a[i]=='o'||a[i]=='u')
    {
    count -=1;
    a[i]=b[count];
    
    }
    }
    cout <<a;
    getch();
    return 0;
}
