Tencent 2014 intern software development test

Because I signed a confidentiality agreement but did not bring my exam out, I just recalled it. I don't know if this is a violation of the Agreement. If yes, contact me.

Several programming questions are recalled here:

Void fun (char ** a) {* a + = 2;} int main () {char * a [] = {"123", "456 ", "abc"}, ** r; r = a; fun (r); printf ("% s", * r );}

This is probably the case. The answer is 3;

Class BASE {public: virtual int foo (int a) {return a * 10;} int foo1 (char a [10]) {return sizeof (a) + 10 ;}}; class Derived: public BASE {public: int foo (int a) {return a * 20;} virtual int foo1 (char a [20]) {return sizeof () + 10 ;}}; int main () {Derived a; BASE * B = & a; char c [10]; cout <B-> foo (100) + B-> foo1 (c );}

The answer is 2014. The array is passed as a parameter, so it should be + 4;

Var a = {"value": "2", "int": 1} var B = a; alert (a. value + B .int );

The answer is 21. javascript knowledge.

The rest will be written later.
