从字符串中删除元音的程序

给定一个字符串，从字符串中删除元音和打印字符串没有元音。

例子：

Input : welcome to geeksforgeeks
Output : wlcm t gksfrgks

Input : what is your name ?
Output : wht s yr nm ?

设计了一个循环，循环通过由该字符串的字符组成的列表，删除元音，然后将其连接。

C++

// C++ program to remove vowels from a String
#include 
using namespace std;
  
string remVowel(string str) 
{
    vector vowels = {'a', 'e', 'i', 'o', 'u',
                           'A', 'E', 'I', 'O', 'U'};
      
    for (int i = 0; i < str.length(); i++) 
    {
        if (find(vowels.begin(), vowels.end(),
                      str[i]) != vowels.end()) 
        {
            str = str.replace(i, 1, "");
            i -= 2;
        }
    }
    return str;
}
  
// Driver Code
int main() 
{
    string str = "GeeeksforGeeks - A Computer"
                 " Science Portal for Geeks";
    cout << remVowel(str) << endl;
  
    return 0;
}

我们可以使用正则表达式来改进上述解决方案。

C++

// C++ program to remove vowels from a String
#include 
using namespace std;
  
string remVowel(string str)
{
    regex r("[aeiouAEIOU]"); 
      
    return regex_replace(str, r, "");
}
  
// Driver Code
int main() 
{
    string str = "GeeeksforGeeks - A Computer Science Portal for Geeks";     
    cout << (remVowel(str));
    return 0;
}
