Program to Delete Vowels from String

As we all know the String is a collection of character data types. In strings, only one variable is declared which can store multiple values. First, we will take the input string from the user. Then we will Delete Vowels from String using the while loop.

With the help of this program, we can Delete Vowels from String.

Algorithm:-

1. Declare the variables for the program. 

2. Take the input string from the user. 

3. <strong>Delete Vowels from String</strong>. 

4. Print the output. 

5. End the program.

Program to Delete Vowels from String:-

#include <stdio.h>
#include <string.h>
int check_vowel(char);

int main()
{
    //declaring the variables
  char s[100], t[100];
  int i, d = 0;
//taking the input string for the program
  printf("Enter a string to delete vowels\n");
  gets(s);

//checking and removing the vowels
  for (i = 0; s[i] != '\0'; i++) {
    if (check_vowel(s[i]) == 0) {     // If not a vowel
      t[d] = s[i];
      d++;
   }
  }
  t[d] = '\0';
  strcpy(s, t);  //optional strig changing
  printf("String after deleting vowels: %s\n", s);
  return 0;
}
int check_vowel(char t)
{
  if (t == 'a' || t == 'A' || t == 'e' || t == 'E' || t == 'i' || t == 'I' || t =='o' || t=='O' || t == 'u' || t == 'U')
    return 1;

  return 0;
}

#include <stdio.h>

#include <string.h>

int check_vowel(char);

int main()

{

//declaring the variables

char s[100], t[100];

int i, d = 0;

//taking the input string for the program

printf("Enter a string to delete vowels\n");

gets(s);

//checking and removing the vowels

for (i = 0; s[i] != '\0'; i++) {

if (check_vowel(s[i]) == 0) { // If not a vowel

t[d] = s[i];

d++;

}

t[d] = '\0';

strcpy(s, t); //optional strig changing

printf("String after deleting vowels: %s\n", s);

return 0;

}

int check_vowel(char t)

{

if (t == 'a' || t == 'A' || t == 'e' || t == 'E' || t == 'i' || t == 'I' || t =='o' || t=='O' || t == 'u' || t == 'U')

return 1;

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

s[100] = it will hold the string value.

t[100] = it will hold the string value.
i = it will hold the integer value.
d = it will hold the integer value.

Taking the input string from the user.

Removing the vowels from the string.

Printing the output.
