sizeof char* array in C/C++

Question

There are plenty of similar inquires, but in my case I don\'t understand what isn\'t working:

int mysize = 0;
mysize = sizeof(samplestring) / sizeof(*samplestrin         


        

Answer 1

The sizeof of an element returns the size of the memory allocated for that object. In your example the string is probably declared somewhere as

samplestring[4]

In which case the size of the memory is 4. The method you probably want in your application is

strlen(samplestring);

Which returns the size of the null terminated string (without the termination)
