For a long time, if you wanted to put a Pascal string literal in your C code, you had to write:

char* str = "\006Hello!";

Yep, you had to count the bytes by hand, yourself, and hardcode it into the first byte of your string. Lazy programmers would do this, and have slow programs:

char* str = "*Hello!";
str[0] = strlen(str) - 1;

Notice in this case you've got a string that is null terminated (the compiler did that) as well as a Pascal string. I used to call thesefucked strings because it's easier than calling them null terminated pascal strings but this is a rated-G channel so you will have use the longer name.
