Debug C ++ -- size_t type! = Int

As follows:Code:

String SA [6] = {"A1", "B2", "C3", "D4", "E5", "F6 "};

Vector <string> SVEC (SA, & SA [6]); // value assignment

Cout <"the value of SA [3] =" <SA [3] <Endl; // true

Cout <"the value of SVEC [3] =" <SVEC [3] <Endl; // error !!

I haven't seen the root cause of this error for a long time. Does vector have no index operator?

The next thought is wrong. As a sequential container, vector should have some basic operators with string objects.

The index value in the original vector must be of the size_t type.ProgramRun as follows!

Size_t Index = 3;

Cout <"the value of SVEC [3] =" <SVEC [Index] <Endl; // true !!

Therefore, you must be careful and careful in future operations.
