Question

Write a program that prompts the user to input a string. The program then uses the function substr to remove all the vowels from the string. For example, if str = "Ther", then after removing all the vowels, str = "Thr". After removing all the vowels, output the string your program must contain a function to remove all the vowels and a function determine whether a character is a vowel. Grading scheme a function to remove all vowels: a function to determ.ne whether a character is vowel: a main function and correct output for any string

Explanation / Answer

#include <iostream>
#include <string>
using namespace std;
bool isvowel(char ch)
{
    if(ch=='a' || ch=='A' || ch=='e' || ch=='E' || ch=='i' || ch=='I' || ch=='o' || ch=='O' || ch=='u' || ch=='U')
    {
        return true;
    }
    return false;
}
string substr(string a)
{
    int i=0;
    while(i<a.length())
    {
        if(isvowel(a.at(i)))
        {
            a.erase(i,1);
        }
        else
        {
            i++;
        }
    }
    return a;
}
int main() {
   // your code goes here
   cout<<"Please enter a string:";
    string a;
    cin>>a;
    a=substr(a);
    cout<<a<<endl;
   return 0;
}
