    FILE *fp = fopen(file, "r");
         
    char ch;
    while ((ch = fgetc(fp)) != EOF)

int main()

    char file[100] = "d:\\data.txt";

    char ch;
    int chars = 0, words = 0, lines = 0;
    while ((ch = fgetc(fp)) != EOF) {
        chars++;
        if (ch == '\n')
            lines++;
        if (ch == ' ' || ch == '\t' || ch == '\n')

    readFile(file);
     
    printf("\n\nTotal chars = %d\n", chars);
    printf("Total words = %d\n", words);
    printf("Total lines = %d\n", lines);
