Question

Write a c program for storing a single word. Based on the character in the word make such an array where all combinations of characters will be available. 

Answer 1

void makeWordList (char *fileName)
{  
FILE *inputFile; 
 char ch; 
int index = 0;
  inputFile = fopen (fileName, "r");
  ch = fgetc (inputFile); 
while (ch != EOF) { if (ch != '\n')
{
  if (index >= CHAR_LIMIT)
 {
printf ("Character limit reached. Exiting program.\n");
exit (0);

then create two files in array then use this code 

 void compareFiles (char *fileName1, char* fileName2) {   }
