Thread: Comparing words in a file...

Hey guys. I'm in the stages of learning C. I'm making a program for practice. What I want the program to do is open a file, then compare all the words inside of it, then display what words that were used more than once. Well, I'm stumped. I've opened the file, and I read all the contents of it, and it can display each word. But, I'm not sure how to go about comparing each word. I think what I have to do is get them inside strings and use strcmp(), but I'm having some trouble. This is my code:

Code:

int main()
{
	char ifilename[] = "c:/test.txt";
    char test;
    
	FILE *fp;

	/* Opens the file, and displays an error if it can't */
    if((fp = fopen(ifilename,"r")) == NULL) {
		printf("Couldn't open for reading.\n");
		exit(1);
	}

	/* Reads all the contents inside the file */
    while((fscanf(fp,"%s", test)) != EOF) {
	printf("%s\n", test);
	}

	fclose(fp);

	return 0;
}

I tried to place each word on an individual line, and then compare each line, but I couldn't get that to work. How would I place each word inside a string?

Quzah, I originally had it as "char test[30];" instead, but before I pasted the code there I was trying to get it to work a different way and forgot to change that back.

Thanks for the quick responses, guys. I'll look into what you both said.
