我们已经在之前章节的各种实例中定义过数字。下面是一个 C++ 中定义各种类型数字的综合实例:
实例
#include <iostream>
using namespace std;
int main ()
{
// 数字定义
short s;
int i;
long l;
float f;
double d;
// 数字赋值
s = 10;
i = 1000;
l = 1000000;
f = 230.47;
d = 30949.374;
// 数字输出
cout << "short s :" << s << endl;
cout << "int i :" << i << endl;
cout << "long l :" << l << endl;
cout << "float f :" << f << endl;
cout << "double d :" << d << endl;
