Description

To remove vowels from string store only consonant in a character array.
The program will take string as a user input and give output a string
having no any vowels.

C/C++

/* C Program to remove vowels from a String*/
//Save it as RemoveVowel.c

#include<stdio.h>
int checkVowel(char);
int main(){

    int i, count=0;
    char str[50], newStr[50];

    printf("Enter a string : ");
    scanf("%s",str);
    
    /*In complete string checking if character is consonent,
      store it in a new character array*/
    for(i=0;str[i]!='\0';i++){
        if(checkVowel(str[i]) == 0){
            newStr[count] = str[i];
            count++;
        }
    }

    //Assigning null at the end of new character array
    newStr[count] = '\0';
    
    //Copying the new character array into a original character array
    strcpy(str, newStr);

    printf("The string after removal of vowel : %s",str);

    return 0;
}

//Function to check vowels in string
int checkVowel(char val){
    if(val=='a' || val=='A' || val=='e' || val=='E' || val=='i' || val=='I' ||
       val=='o' || val=='O' || val=='u' || val=='U'){
        return 1;
    }else{
        return 0;
    }
}

Input:
Enter a string : sachin

Output:
The string after removal of vowel : schn
