In a low-level language like C, null,' \' ,false, etc. are all stored as x

But in later high-level languages, these types are different, such as VB under VS compiler.

The result of the actual execution of the landlord assignment statement is:

x[]=x;

x[1]=x;

x[2]=x3;

x[3]='i';

x[4]='n';

x[5]='g';

x[6]=x3;

so sizeof(x)=7

strlen(x))=.
