How to delete the vowels from a given string using C language?

The logic we use to implement to delete the vowels from the given string is as follows −

for(i=0; i<len; i++) //repeat until i<len{
   if(str[i]=='a' || str[i]=='e' || str[i]=='i' || //checking to delete the vowels
   str[i]=='o' || str[i]=='u' || str[i]=='A' ||
   str[i]=='E' || str[i]=='I' || str[i]=='O' ||
   str[i]=='U'){
      for(j=i; j<len; j++){
         str[j]=str[j+1];
      }
      len--;
   }
}

Example

Following is the C program for deleting the vowels in a given string −

#include<stdio.h>
#include<conio.h>
#include<string.h>
void main(){
   char str[20];
   int len, i, j;
   clrscr();
   printf("Please Enter any String: ");
   gets(str);
   len=strlen(str);
   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' || str[i]=='U'){
         for(j=i; j<len; j++){
            str[j]=str[j+1];
         }
         len--;
      }
   }
   printf("After Deleting the vowels, the String is: %s",str);
   getch();
}

Output

When the above program is executed, it produces the following result −

Please Enter any String: TutorialsPoint
After Deleting the vowels, the String is: TtralsPint
