Question

Write a C++ 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 = "There", the function would remove the 2 e's and output "Thr". Your program needs to contain a main routine, and a function to remove all the vowels, and a function to determine whether a character is a vowel.

This is what I have so far!

[code]
#include <iostream>
#include <string>

using namespace std;



int main()



{

string word;

cout << "Enter a sting" << endl;

getline (cin,word);



for(int i=0; i<word.length(); i++)

{

if(name[i] == "a,e,i,o,u")

string sub = [i]

}

cout << string

char any_keystroke;
//reads and ignores up to 200 characters, or ' ' is read and ignored
cin.ignore(200, ' ');
cout << " ";
cout << "Program execution has ended normally. ";
cout << "Press the enter key to exit.";
cin.get(any_keystroke);

return 0;



}

Explanation / Answer

please rate - thanks #include <iostream>
#include <string>
using namespace std;
string removevowels(string&);
bool isvowel(char);
int main()
{
string word;
cout << "Enter a string" << endl;
getline (cin,word);
cout<<"with vowels: "<<word<<endl;
word=removevowels(word);
cout<<"without vowels: "<<word<<endl;
char any_keystroke;//reads and ignores up to 200 characters, or ' ' is read and ignored
cin.ignore(200, ' ');
cout << " ";
cout << "Program execution has ended normally. ";
cout << "Press the enter key to exit.";
cin.get(any_keystroke);
return 0;
}
string removevowels(string& word )
{int i,prev=0;
string result="";
for(i=0;word[i]!='';i++)
     if(isvowel(word[i]))
         {result=result+word.substr(prev,i-prev);
          prev=i+1;
          }
result=result+word.substr(prev,i-prev);
return result;
}                                                                                                                                                                                                                                                                                  
bool isvowel(char in)
{bool value=false;
     switch(in)
   { case 'a':
     case 'A':
     case 'e':
     case 'E':
     case 'i':
     case 'I':
     case 'o':
     case 'O':
     case 'u':
     case 'U':      value= true;
