The number of bytes consumed by the C basic data type can be obtained by the following example:#include intMainvoid) {printf ("char size=%d \ n",sizeof(Char)); printf ("int size=%d \ n",sizeof(int)); printf ("long size=%d \ n",sizeof(Long)); printf (

A simple example:#include using namespacestd;intSumintXinty) { returnX +y;}intMain () {cout1,2) Endl; int(*PF) (int,int);//not initializedPF =sum; cout3,4) Endl; /*Output:3 7*/ return 0;}In case of overloading, the compiler precisely matches

Microsoft MSDN defines covariance and contravariance as follows:When you match a method signature to a delegate type, covariance and contravariance become a certain degree of flexibility. Covariant allows methods to have more derived return types
