如何将用户输入与存储在文件中的字符串进行比较？

Question

I gotta write a file-handing code which will compare the string received from the user to a string of char stored into a file in C. I've trying since yesterday. I have no clue on how to do that. I tried many things, but nothing seems to work.

int main (int argc, const char * argv[]){

    FILE *file = fopen("file.txt", "w");
    char text[] = "hi hi hi hi hi hi"; //string to be allocated into the file
    char c, userInput[] = "hi"; // simulates the user input
    int i = 0, count = 0;



    if (file == NULL) {
        printf("Failure to create file.\n");
        exit(1);
    } else {
        for (i = 0; i < strlen(text); i++) {
            printf("Inserting: [%c]\n", text[i]);
            fputc(text[i], file);
        }
        printf("All done.\n");
    }
    fclose(file);


    fopen("file.txt", "r");
    while ((c = fgetc(file) != EOF)){
        fscanf(file,   "%s",   text);
        if (strcmp(userInput, text) == 0) {
            count++;
        }
    }
    fclose(file);



    printf("Many times present: %d\n", count);
    return 0;
}

My problem is... the space between every word of the string in the file, because I have to check if there's another word starting, for instance... (Hi Hi)... I thought about using something like this in my code but I did not work as well.

while ((c = fgetc(file) != EOF)){ // While the end of the file does not happen keep running.
    if ((c = fgetc(file) != ' ')) { //If an blank space is found... I does not make any sense actually. I'm desesperated.
        strcmp(userInput, text){
            count++
        }
    }
}

while ((c = fgetc(file) != EOF)){ 
    if ((c = fgetc(file) != ' ')) { 
        strcmp(userInput, text){
            count++
        }
    }
}

There are three major problems here.

First, c = fgetc(file) != EOF is the same as c = (fgetc(file) != EOF) which obviously is not what you want. It should be (c = fgetc(file)) != EOF

Second, the above statement has (provided you did not get an EOF) actually read a character. So the if statement should be if(c != ' ')

Third, c needs to be declared as an int
