Write a C program which reads the standard input and extract

Write a C program which reads the standard input and extract HTML-style tags from it. We consider that the HTML-style tags are all strings starting with character “less-than” (<) and end with the character “greater-than” (>). In case that there is a tag starting with ‘<’ but not finishing with ‘>’ at all, then print it all the way to the end of input. Each tag should start at a new line. Input The input is in a free textual form. Output The output consists of a list of tags in the order that they appear in text. Each tag should start on a new line. All content of a tag should be printed in the same way as it appears in input. If a tag is not finished, it should still be printed. The sample input and output below illustrate behaviour of the program.

Hint : The program should read input character by character and immediatelly produce output or not based on the context.

Hint : you can use getchar() and putchar() OR scanf() and prinf()

Solution

/* Program Code Begins */

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

int ch,temp=0,temp2=0,i=0,j=0;
char ch2;
char ch5[1000];

printf(\"Enter input data :\ \");
    while ( ( ch=getchar() ) != EOF ) // read characterwise input data until EOF,in Windows Ctrl+Z /unix Ctrl+D is equal to End of File character
    {
      ch5 [i]=ch;                         //write single input char into char array.
      i++;
   }
   j=i;
   i=0;
   printf(\"Input Reading Stopped : Outpue Generating .......\");


   while (j>=0 )        //read character wise data from array untilllast char.
    {
         ch2=ch5[i];
         i++;
         j--;
        if(temp==0)                               //temperory varible to taken avoid other chars in input except html content
        {
            if(ch2==\'<\')                       //condtions to display html contents
       {
           temp=1;
           printf(\"\ \");
        
       }
   }
    
       if(temp==1)                                   //temperory varible to taken avoid other chars in input except html content
       {
           if(ch2!=\'\ \')
           printf(\"%c\",ch2);
           if(ch2==\'>\')                               //condtions to display html contents
           {
               temp=0;
               printf(\"\ \");
           }
        
       }
    
   }

return 0;
}

Input :

Enter input data :
