I need some help with a program that I am writing for my Systems Programming class. It is in C and I have very, very little experience with C. I need to merge three text file with the format:
word1
word2
word3
...
wordX
I am also to bring each of the words from all three files and put them into a 2D array (an array of string-arrays), then use some sort of sorting method on them.
I shouldn't need help with the sorting, but I don't know how to get the word count from each of the text files or put them into an array.
This is the function I have for counting the words in the file. It doesn't compile on gcc
(probably for obvious reasons, but I don't know them). Do I even have the right idea?
int countWords(FILE f){
int count = 0;
char ch;
while ((ch = fgetc(f)) != EOF){
if (ch == '\n')
count++;
//return count; originally here, but shouldn't be.
}
return count;
}
EDIT: I supposed I could just find a way to count the lines in the program, but I'm not sure if the approach would be any different from what I am trying to do here. (I have never really been that good at working with text files.
I got it to count all of the lines in the program. I guess I'm a little rusty.
#include <stdlib.h>
#include <stdio.h>
int countWords(FILE *f){
int count = 0;
char ch;
while ((ch = fgetc(f)) != EOF){
if (ch == '\n')
count++;
}
return count;
}
int main(void){
int wordCount = 0;
FILE *rFile = fopen("american0.txt", "r");
wordCount += countWords(rFile);
printf("%d", wordCount);
return 0;
}
I kind of forgot about that the pointer thing with FILE *fileName
It should be int countWords(FILE *f){
, with *
. And the return
statement should go before the last }
only, outside the loop.
