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:

我需要一些幫助,我正在為我的系統編程課程編寫一個程序。它在C中,我對C的經驗非常非常少。我需要將三個文本文件合並為以下格式:

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.

我還要將所有三個文件中的每個單詞都放入一個2D數組(一個字符串數組的數組)中,然后對它們使用某種排序方法。

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.

我不需要幫助排序,但我不知道如何從每個文本文件中獲取字數或將它們放入數組中。

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?

這是我用來計算文件中單詞的函數。它不能在gcc上編譯(可能原因很明顯,但我不知道)。我甚至有正確的想法嗎?

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.

編輯:我想我可以找到一種方法來計算程序中的行數,但我不確定這種方法是否會與我在這里嘗試的方法有所不同。 (我從來沒有真正善於處理文本文件。

Holy cow. I got it to count all of the lines in the program. I guess I'm a little rusty :P

天啊。我得到它來計算程序中的所有行。我想我有點生氣:P

#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

我有點忘了FILE * fileName指針的東西

Thanks for the help guys.

謝謝你的幫助。

#include<stdio.h>
#define FILE_READ "file.txt"

    int main()

{
    FILE * filp;
    int count = 1;
    char c;
    filp = fopen(FILE_READ, "r");
    if(filp == NULL)
        printf("file not found\n");
    while((c = fgetc(filp)) != EOF) {
        if(c == ' ')
            count++;
    }
    printf("worrds = %d\n", count);
    return 0;
}

I am megharaj, from india.

worrds = 5
