# C program to remove vowels from a string.

## How to remove vowels from a string.

In this article we will learn how to code a C program to remove vowels from a string. ‘A’, ‘E’, ‘I’, ‘O’, ‘U’ are five vowels out of 26 characters in English alphabet letters.C programming is case sensitive, and hence lowercase and uppercase characters are considered differently, so we will have to check for both the cases and then we can remove the vowels from a string

## Algorithm:

• Initialize the variables.
• Accept the input.
• Initialize for loop.
• Check and delete the vowels.
• Store the string without vowels using another for loop.
• Terminate both for loop.
• Print the string without vowels.

## C programming code to remove vowels from a string.

`#include <stdio.h>#include <string.h>int main(){	//Initializing variable.	char str[100];	int i,j,len=0;		//Accepting input.	printf("Enter a string : ");	//gets(str);	scanf("%s",str);	len=strlen(str);		//Accepting input.	for(i=0; i<len; i++)	{   	    //Checking vowels.		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')		{		    		    //Deleting vowels. 			for(j=i; j<len; j++)			{			    //Storing string without vowels.				str[j]=str[j+1];			}			i--;		    len--;		}		str[len+1]='\0';	}		printf("After deleting the vowels, the string will be : %s",str);        return 0;	}`

## Output

`Enter a string : aaabbbeeecccAfter deleting the vowels, the string will be : bbbccc`

#include
#include
int main()
{
//Initializing variable.
char str[100];
int i,j,len=0;

//Accepting input.
printf(“Enter a string : “);
gets(str);
len=strlen(str);

//Accepting input.
for(i=0; i<len; i++)
{
//Checking vowels.
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')
{

//Deleting vowels.
for(j=i; j<len; j++)
{
//Storing string without vowels.
str[j]=str[j+1];
}
len–;
i–;
}
}
printf("After deleting the vowels, the string will be : %s",str);

return 0;
}

If you dont write i– where i have written if there is consecutive vowels in a string it will skip the second vowel plz rectify it
