编程学习网为您整理以下代码实例，主要实现：C++定义数字，希望可以帮到各位朋友。
#include <iostream>
using namespace std;
int main () {
// number deFinition:
short s;
int i;
long l;
float f;
double d;
// number assignments;
s = 10;
i = 1000;
l = 1000000;
f = 230.47;
d = 30949.374;
// number printing;
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;
return 0;
