strstr not functioning

Question

Why does this particular piece of code return false on the strstr() if I input \"test\"?

char input[100];

int main()
{
    fgets(input, 100, stdin);
    pri         


        

Answer 1

Add input[strlen(input) - 1] = '\0'; after the fgets. fgets reads in the newline char ('\n'). There is no '\n' in "test message" so input will never be contained within it.

You should really check to see if the newline is at the end of the buffer after calling fgets to know if the whole line was able to actually fit into it, and also to obviously remove it.
