I am a relative novice at java but have absolutely no comprehension of C. Foolishly i took on the task of translating a small C program to java as a favour for someone and have become completely stuck. Please could someone convert the C program below as a massive favour to a needy greenhorn.
/////////HERE IS THE C PROGRAM///////////?
// A program to read in a list of rare wildlife, sort it and write out a
// html file.

#include <condefs.h>
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <string.h>
// Useful constants
#define MAX 1000
#define STRING 100
// Function prototypes
void write_header(FILE *f1);
int bubble_sort(int nr_animals, int count[STRING], char species[MAX][STRING],
 char family[MAX][STRING],char country[MAX][STRING]);
void write_animal(FILE *f1,char species[STRING],int count,char family[STRING],
 char country[STRING]);
//---------------------------------------------------------------------------
void main(int argc, char* argv[])
{
 char filename[128];
 int passes=0;
 int count[MAX];
 char species[MAX][STRING];
 char family[MAX][STRING];
 char country[MAX][STRING];
 char dummy[STRING];
 printf("Enter the file name containing the list of endangered species :");
 scanf("%s",filename);
 FILE *f1;
 f1 = fopen(filename,"rt");
 int nr_animals=0;
 if(!f1) {
 printf("File not found");
 exit(0);
 }
 do {
 // Read in a whole line
 fgets(species[nr_animals],STRING,f1);
 // Read in an integer
 fscanf(f1,"%u",&count[nr_animals]);
 // Mop up the rest of the line.
 fgets(dummy,STRING,f1);
 fgets(family[nr_animals],STRING,f1);
 fgets(country[nr_animals],STRING,f1);
 // repeat the loop until an end of file is reached
 nr_animals++;
 } while(!feof(f1)) ;
 nr_animals--;
 int i;
 passes=bubble_sort(nr_animals, count,species,family,country);
 printf("Number of passes required to sort the data %u\n",passes);
 printf("Number of animals: %u\n",nr_animals);
 fclose(f1);
 // Write the sorted data out as a html file
 printf("Enter the output file name :");
 scanf("%s",filename);
 f1 = fopen(filename,"wt");
 if(!f1) {
 printf("Error when opening file %s",filename);
 exit(0);
 }
 // Write html header
 write_header(f1);
 // Write out sorted endangered species.
 for( i = 0; i < nr_animals; i++) {
 write_animal(f1,species[i],count[i],family[i],country[i]);
 }
}

int bubble_sort(int nr_animals, int count[STRING], char species[MAX][STRING],
 char family[MAX][STRING],char country[MAX][STRING]){
 int passes;
 passes = 0;
 int sorted;
 sorted = 0;
 int j;
 char c[STRING];
 while(!sorted) {
 sorted=1; // Set sorted to be true (for now)
 passes++;
 for(j = 0; j < nr_animals-1; j++) {
 //Swap over the species if necessary
 if(strcmp(species[j],species[j+1]) > 0) {
 strcpy(c,species[j]);
 strcpy(species[j],species[j+1]);
 strcpy(species[j+1],c);
 strcpy(c,country[j]);
 strcpy(country[j],country[j+1]);
 strcpy(country[j+1],c);
 strcpy(c,family[j]);
 strcpy(family[j],family[j+1]);
 strcpy(family[j+1],c);
 int temp=count[j];
 count[j]=count[j+1];
 count[j+1]=temp;
 // Still not sorted, therefore set false...
 sorted=0;
 }
 }
 }
 return passes;
}

void write_header(FILE *f1) {
 // Write out a html header
 fprintf(f1,"<html>\n<head>\n<title>The top-ten list of endangered species");
 fprintf(f1,"</title></head>");
}
void write_animal(FILE *f1,char species[],int count,char family[],char country[]) {
 // Write out the details of one endangered animal, with suitable html formatting.
 fprintf(f1,"Animal %s\n",species);
 fprintf(f1,"Count %u\n",count);
 fprintf(f1,"family %s\n",family);
 fprintf(f1,"Country %s\n",country);
}

This would be a good homework assignment.

Hi Robert,
Without a sample input and output file this might not be that easy.
