c++数据类型

各数据类型最大限度

​
#include<iostream>
using namespace std;
//数据类型存在的意义:给变量分配合适的内存空间,取值范围也不同,如果超过取值空间，就会回到最小值
int main()
{
	//1.短整型
	short num1 = 10;
	short num5 = 52525255232;//(超过最大值)

	//2.整型
	int num2 = 10;

	//3.长整型
	long num3 = 10;

	//4.长长整型
	long long num4 = 10;

	cout << "num1 = " << num1 << endl;
	cout << "num2 = " << num2 << endl;
	cout << "num3 = " << num3 << endl;
	cout << "num4 = " << num4 << endl;
	cout << "num5 = " << num5 << endl;

	system("pause");

	return 0;
}
