Remove or Delete Vowels from a String

Write a C++ Program to Remove or Delete Vowels from a String. Here’s simple C++ Program to Remove or Delete Vowels from a String in C++ Programming Language.

C++ Strings : 

String is a sequence of characters. char data type is used to represent one single character in C++. So if you want to use a string in your program then you can use an array of characters.

The declaration and definition of the string using an array of chars is similar to declaration and definition of an array of any other data type.

Any string ends with a terminating null character ‘\0’. An array definition in such a way should include null character ‘\0’ as the last element.

C++ provides following two types of string representations:

  • The C-style character string.
  • The string class type introduced with Standard C++.

The C-style character string originated within the C language and continues to be supported within C++. This string is actually a one-dimensional array of characters which is terminated by a null character ‘\0’. Thus a null-terminated string contains the characters that comprise the string followed by a null.

Here is source code of the C++ Program to Remove or Delete Vowels from a String. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


/*  C++ Program to Remove or Delete Vowels from a String  */

using namespace std;

int main()
    char str[50],str1[50];
        int len, i, j;
        cout<<"\nEnter any string :: ";


        for(i=0; i<len; i++)
                if(str[i]=='a' || str[i]=='e' || str[i]=='i' ||
                str[i]=='o' || str[i]=='u' || str[i]=='A' ||
                str[i]=='E' || str[i]=='I' || str[i]=='O' ||
                        for(j=i; j<len; j++)
        cout<<"\nAfter Deleting the vowels, the string [ "<<str1<<" ] will be : "<<str<<"\n";

        return 0;


/*  C++ Program to Remove or Delete Vowels from a String  */

Enter any string :: CodezClub

After Deleting the vowels, the string [ CodezClub ] will be : CdzClb

Process returned 0

If you give input as heelloo it will give output as hello because this program doesnot work when two vowels are together
