segmentation fault with strlen

[Thegame16]

Hey guys I have a function that looks like this:int check(const char str[])

I am trying to count the size of the string length using strlen but it keeps giving me a segmentation error. Does anyone know why this is happening and how I can fix this?

#include <stdio.h>
#include <string.h>

int check(const char str[])
{
int a;


a=strlen(str)

    if(a==10)
    {
      /*execute this block of code */
    }


}

You need to make sure str[] is terminated by a 0, otherwise strlen() will run off the end and cause the seg fault.

how do i do that?

Maybe you've declared your argument wrong. Try using a const char * instead. Also, it would help to post how you're using the check() function.

Also, check() doesn't return anything, so change it's return type to void.

Check the code that calls the function. The function itself cannot sensibly perform such a check.

It is the same thing in this context.
