Question

Take the Java program Pretty.java and convert it to the equivalent C program. You can use the file in.txt as sample input for your program.

v  import java.io.*;
import java.util.*;

public class Pretty
{
  public static final int LINE_SIZE = 50;
  
  public static void main(String[] parms)
  {
    String inputLine;
    int position = 1;
    Scanner fileIn = new Scanner(System.in);

    while (fileIn.hasNextLine())
    {
      inputLine = fileIn.nextLine();

      if (inputLine.equals(""))
      {
        if (position > 1)
        {
          System.out.println();
        }
          
        System.out.println();
        position = 1;
      }
        
      else
      {
        if ((position+inputLine.length()-1) > LINE_SIZE)
        {
          System.out.println();
          position = 1;
        }
        System.out.print(inputLine);
          
        position += inputLine.length();
        if (position <= LINE_SIZE)
        {  // add a blank after the current w
          // ord
          System.out.print(" ");
          position++;
        }
      }   
    }      
  }
}

Please note the output is supposed to change the input in.txt from this;

Introduction

I've been involved with XP for a couple of years
now and where I've seen XP implemented properly it
seems to have worked extremely well. But there
does seem to be an awful lot of opponents to XP in
the industry and this baffles my colleagues and I
at eXoftware. To us XP is just a better way of
producing code and we just can't imagine any
coding shop not wanting to produce better code. We
think that the reason some people and
organisations are antagonistic to XP (and the
arguments do get very heated sometimes) is
culture. Their cultures simply don't allow
practices such as those proposed by XP.

SOLUTION-
I have solve the problem in C code with comments and screenshot for easy understanding :)

CODE-

//c code for java
#include <stdio.h>
#include <string.h>
#define LINE_SIZE 50

int main(int argc, char* argv[])
{
FILE* file = fopen("in.txt", "r"); // reading the input file in.txt
char line[1000000]; // char array to store content in lines
  
int position = 1; // set position to 1
while (fgets(line, sizeof(line), file)) // runs while loop until all the content of file is read
{
if(strcmp(line,"")==0) // if the line in a file is empty
{
if(position > 1) // if position is greater than 1 print a new line
{
printf("\n");
}
printf("\n");
position =1; // set the position as 1
}
else // if line in a file is not empty
{
if((position + sizeof(line)-1) > LINE_SIZE) // if condition is true
{
printf("\n"); // print a new line
position = 1; // set position =1
}
printf("%s",line); // print the current line

position += sizeof(line); // sizeof is used to calculate length of the line
if(position <= LINE_SIZE)
{
printf(" ");
position++;
}
}
  
}

fclose(file); // close the file

return 0;
}
