Question

I’m new to C but I have experience in Java and Android.
I have a problem in my for loop. It will never end and just go on and on.

char entered_string[50];
char *p_string = NULL;

gets( entered_string );

for( p_string = entered_string; p_string != '\0'; p_string++ ){
    //....
}

I know that gets is unsafe, not recommended and deprecated but according to my specs I have to use it. I want to loop through each element by using pointers.

Answer 1

Your test should be *p_string != '\0';

p_string is a pointer, and your loop is checking if the pointer is != '\0'. You’re interested in if the value is != '\0', and to get the value out of a pointer you have to dereference it with *.
