查看变量类型大小.cpp

C++编写的程序源码,里有21天学通C++的课后作业源码和章节源码.

#include<iostream>
int main()
{
	using namespace std;
	cout<<sizeof(char)<<"--字符型\n";
	cout<<sizeof(short int)<<"--短整型\n";
    cout<<sizeof(long int)<<"--长整型\n";
	cout<<sizeof(double)<<"--双精度\n";
	cout<<sizeof(unsigned short int)<<"--无符号短整型\n";
	cout<<sizeof(unsigned long int)<<"--无符号长整型\n";
	cout<<sizeof(bool)<<"--布尔型\n";
	cout<<sizeof(float)<<"--浮点型\n";
	cout<<sizeof(int)<<"--整型\n";
	cout<<"    由于整型的大小是4 bytes个，说明你的机子是32位的机子。谢谢大家···\n";
