Topics: Files, loops, functions, arrays

Write a program that repeatedly asks the user to enter a word.  After each word is entered, the program tells the user if the word is correctly spelled or not.

Sample run:

Welcome to the spell checker!  Please enter a word:

> apple

The word apple is spelled correctly!

Enter another word:

> snake

The word snake is spelled correctly!

Enter another word:

> compooter

WHOA!  compooter isn’t a word!  Bad human! Learn to spell!

> dinosore

WHOA! dinosore isn’t a word!  Bad human!  Learn to spell!

To solve this problem:  Download the following text file to your program directory.  This file is a dictionary listing ALL THE WORDS IN THE ENGLISH LANGUAGE:  largedictionary.txt

This file contains exactly 202,412 words (you may use this number to decide how big to make your array, if you like). A very smart approach is to create a smaller version of the dictionary (say 10 words) for testing to get things working first.

Suggestion:  Break the problem down into steps.  For example, you might implement the following “pseudo code”:

1)Create a giant array.  Read each word in from the dictionary file and store the word in the array.

2)Enter a loop in which you ask the user to enter a word.

a)Check if the word entered is in your giant array of words.

i)If so, congratulate the user.

ii)If not, berate the user for their flawed spelling.

Explanation / Answer

#include<stdio.h>
#include<string.h>
#include<stdlib.h>

char dic[10][15];

int main()
{
FILE *file; /* declare a FILE pointer */
int cnt=0,i=0;
char line[20];
char cmp[20];
int len=0;
int success=1;

file = fopen("data.txt", "r"); /* open a text file for reading */

while(fgets(line, sizeof line, file)!=NULL) { /* keep looping until NULL pointer... */
len = strlen(line);
line[len-1]='';
strcpy(dic[cnt],line);
cnt++;
}
while(1) /* keep looping */
{   
success =1 ;
printf("Enter Word ");
scanf("%s",cmp);
  
for(i=0; i<cnt; i++){
if(strcmp(cmp,dic[i])==0){ /* compaire the word */
printf("The word %s is spelled correctly! ",dic[i]);
success = 0;
break;
}
}
if(success != 0)
printf("WHOA! %s isn’t a word! Bad human! Learn to spell! ",cmp);
}
return 0;

}
