Program to Delete Word 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 the Word from String using the while loop.

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

Algorithm:-

1. Declare the variables for the program. 

2. Take the input string from the user. 

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

4. Print the output. 

5. End the program.

5. End the program.

Program to Delete Word from String:-

#include<stdio.h>
#include<string.h>
int main()
{
   //declaring the variable for the program
   char str[100], word[20];
   int i, j, ls, lw, temp, chk=0;
   //Getting input string from the user 
   printf("Enter the String: ");
   gets(str);
   //Taking the removing word from the user
   printf("Enter a Word: ");
   gets(word);
   //Using the string functions
   ls = strlen(str);
   lw = strlen(word);
   
   for(i=0; i<ls; i++)
   {
      temp = i;
      for(j=0; j<lw; j++)
      {
         if(str[i]==word[j])
            i++;
      }
      chk = i-temp;
      if(chk==lw)
      {
         i = temp;
         for(j=i; j<(ls-lw); j++)
            str[j] = str[j+lw];
         ls = ls-lw;
         str[j]='\0';
      }
   }
   //Printing the output string with out the taken word
   printf("\nNew String = %s", str);
   return 0;
}

#include<stdio.h>

#include<string.h>

int main()

{

//declaring the variable for the program

char str[100], word[20];

int i, j, ls, lw, temp, chk=0;

//Getting input string from the user

printf("Enter the String: ");

gets(str);

//Taking the removing word from the user

printf("Enter a Word: ");

gets(word);

//Using the string functions

ls = strlen(str);

lw = strlen(word);

for(i=0; i<ls; i++)

{

temp = i;

for(j=0; j<lw; j++)

{

if(str[i]==word[j])

i++;

}

chk = i-temp;

if(chk==lw)

{

i = temp;

for(j=i; j<(ls-lw); j++)

str[j] = str[j+lw];

ls = ls-lw;

str[j]='\0';

}

//Printing the output string with out the taken word

printf("\nNew String = %s", str);

return 0;

}

Output:-

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

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

word[20] = it will hold the string value.
i = it will hold the integer value.
j = it will hold the integer value.

chk = it will hold the integer value.
temp = it will hold the integer value.
ls = it will hold the integer value.

lw = it will hold the integer value.

Taking the input string from the user.

Using string function to get the length of string and the word.

Removing the word from the string.

Printing the output.
