Top Forums Programming 'strlen' of a constant string Post 302224605 by cleopard on Wednesday 13th of August 2008 02:01:57 PM

And one more thing: why if you have a declaration like this:


char str[] = "teststring";

int str_l = sizeof(str);


will it set 'str_l' to 11, not 10? Is it counting the null byte?

String Constant C

I wonder string constant exists permanently or temporary. For example, printf("hello, world"); the function printf access to it is through a pointer. Does it mean storage is allocated for the string constant to exist permanently in memory? :confused: (4 Replies)
