How to compare substrings with strings?

Ok maybe my topic is extremely vague.

For example if I had an 2-d character array called:
char testArray[5][11];

which contains:
1) Hello
2) Pirate
3) Beef
4) Youtube
5) Random

And I have another character string which is:
char compareThis[11] = "eef";

How can I make a specific code which checks compareThis for all 5 strings.
And checks that testArray[2] contains "Beef" which contains the substring of "eef"

Or another case is checking for the substring "ell", which is a substring of testArray[0] that contains "Hello"

Put strstr in a loop.

strstr reference: http://www.cplusplus.com/reference/c...ng/strstr.html

Just a question.
What is a null pointer?

A pointer that doesn't point anywhere. Represented by "NULL". Also represented by "0", but people tend to use "NULL" to prove to other people they know what they're doing.

How would I compare that?

ptr = strstr(str1,str2);

if (ptr != '0')
......

Will this work?

Not '0', which is the character '0', but just plain old 0, or just plain old NULL.

Im trying to do this...

Code:

---

int main()
{
        char str1[5][11];
        char str2[6] = "Mou";
        char * cmpValue;
        int x = 0;

        strcmp(str1[0],"Hello");
        strcmp(str1[1],"Bigg");
        strcmp(str1[2],"Mouse");
        strcmp(str1[3],"Keyboard");
        strcmp(str1[4],"Pong");

        for (x = 0;x < 5;x++ )
        {
                cmpValue = strstr(str1[x],str2);

                if (cmpValue != NULL)
                {
                        printf("This is it!\n");
                }
                else
                {
                        printf("Nope, not this one\n");
                }
        }
}

But it just passes everything as "else"

You've managed to put strcmp in place of strcat in several lines of code.

OH! Oh my! Thats so embarassing!

My bad =)

And to make things worse, I said strcat when I obviously meant strcpy.

Hahahaha, Yeah I noticed that. I placed STRCPY instead.

But wouldn't it make a difference in this case?
Its empty to begin with so I guess strcat is passable right?

Anyways, I got it working!
Thanks a bunch guys!

They're not empty, they're filled with randomness. Not the same thing.
