sizeof问题

#include <iostream>int main(int argc, char *argv[]){char str[] = "game";std::cout<<sizeof(str)<<":";char *p = str;std::cout<<sizeof(p)<<":";char i = 10;std::cout<<sizeof(i)<<":";void *pp = malloc(10);std::cout<<sizeof(pp)<<":";free(pp);char a[100] = {'a','b',0};//0为'/0'的ASCII码，作为结束符std::cout<<sizeof(a)<<":"<<strlen(a)<<std::endl;}

 

输出结果为：

5:4:1:4:100:2
