从C中的文件读取字符串的问题

Question

I've tried to look for a similar problem but was unable to find it so I'm posting this. Here's the thing. Let's say I have a file named text.txt. Now, the file consists of 3 integers and string, something like this:

4 59 32 This is sentence 1
5 9 130 Grass is green
3 12 149 I need help

I'm still learning C so I'm sorry if this is some easy type question etc. Here's the problem. I don't know how to read this. The same is if the string is at the beginning of the file like this

This is sentence 1 4 59 32
Grass is green 5 9 130 
I need help 3 12 149 

I know how to read it if I know the amount of words it will consist of (like if the file would be something like Name Surname Number Number Number) but this when I need to read entire, I have no idea.

Here's the code from comments. However, as @john pointed out, it's false right from the start since i gets first character and then I do scanf (still, I've tried out and with only numbers involved, fscanf gets correct values even though first character is read). I was also thinking about some while loop with isalpha() and isspace() involved but to no avail.

while((i = fgetc(input)) != (int)(EOF))
    {
        fscanf(inputFile, "%d %d %d", &num1, &num2, &num3);

        j=0;
        while(i != (int)('\n'))
        {
            string[j++]=(char)i;
            i = fgetc(inputFile);
        }
        string[j] = '\0';

        printf("%d %d %d %s\n",br1, br2, br3, string);

You're right, it's wrong. There's no need to consume a line's first character just to test for EOF - we can leave that to fscanf() .
Also there's no need to read the string's characters one by one - fscanf() can read a string ending at \\n with the conversion specification %[^\\n] .
If the input string length is not limited, we'd have to prevent the buffer overflow when the input string would need more memory than provided by string by adding a maximum field width . If you defined eg char string[100]; , the maximum field width is 99, since the last char is needed for the terminating null character.
So we could write eg

    while (fscanf(input, "%d %d %d %99[^\n]", &num1, &num2, &num3, string) == 4)
        printf("%d %d %d %s\n", num1, num2, num3, string);
