Consider my following code:

int main() {
    int letter_count=4;
    char tempstring[6];
    char userStrings[4][4];
    for(int i=0;i<4;i++){

        fgets(tempstring,letter_count+1,stdin);

        tempstring[strcspn(tempstring, "n")] = 0;

        strcpy(userStrings[i],tempstring);

        printf("n%s found from %dn",userStrings[i],i);

}
    return 0;
}

Now, what I am trying to do is: I want the user to input 4 words. Here, fgets() caputures these inputs. So, whenever, I try to input something smaller than 4 words, say foo and press enter the output is:
foo found from 0
But, whenever, I enter something of 4 words or more than that, it becomes unexpected. Consider, I input foil and press enter, this is what happens:

foil found from 0

 found from 1

Why is there a line found from 1. The string tempstring has somewhat received a whitespace from the user input and the loop has advanced by one step, which should not have been the case. What I anticipate is, since fgets() receives more than five characters from user, it advances the loop once. Is there any way, I just want fgets() to receive exactly four letters or less and let the loop run only once?

I may try scanf() and gets(), but they cannot limit the size of user input. Any suggestions would gladly help me. Thanks.
