文本中的常量字数

Question

我尝试编写一个程序来计算从文件中获取的文本中的单词数。我有一个问题，编译器找不到我的文件，但是我将此文件放在项目文件夹中。 我能做什么？

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

int words(const char sentence[ ]);

int main(void) {
    char sentence[100];
    FILE *cfPtr;

    if ( (cfPtr = fopen("C programming.dat", "r")) == NULL ) {
        printf( "File could not be opened\n" );
    }
    else {
        fscanf(cfPtr, "%s", sentence);
    }

    words(sentence);
    printf("%d", words(sentence));
    getch();
    return 0;
}

int words(const char sentence[ ]) {
    int i, length = 0, count = 0, last = 0;
    length = strlen(sentence);

    for (i = 0; i < length; i++)
        if (sentence[i] == ' ' || sentence[i] == '\t' || sentence[i] == '\n')
            count++;

    return count;
}

我将尝试提高程序的可用性，接受文件名作为可选参数

int main(ant argc, char *argv[]) {
    char sentence[100];
    const char *filename = "C programming.dat";
    FILE *cfPtr;

    if (argc == 2)
       filename = argv[1];

    if ( (cfPtr = fopen(filename, "r")) == NULL ) {
        printf( "File '%s' could not be opened\n", filename );
    }
    else {
        int total = 0;
        while (fgets(sentence, sizeof sentence, cfPtr))
           total += words(sentence);
        printf("%d", total);
        fclose(cfPtr);
    }
    getch();
    return 0;
}
...
