允许int*到void*的转换,反之不亦然：无效的转换invalid conversion from `void*' to `int*'

#include <iostream>
using namespace std;

int main( void )
{
    int cpp = 2002;
    
    int *pCpp = &cpp;
    
    void *pVoid = &cpp; //可以从int*到void*的转换 

    
    //int *pInt = pVoid; //不能从void* 到int*的转换 

    //invalid conversion from `void*' to `int*' 

    //编译器说这是一个无效的转换 

    
 	system( "PAUSE" );
 	return EXIT_SUCCESS;
