3章4节给变量赋值

#include <iostream>

int main()
{
using std::cout;
using std::endl;

short unsigned int width = 5, length;
length = 10;
// 定义变量和赋值变量可以一次多个 并可以混合

unsigned short int area = (width * length);

cout << " width = " << width << endl;
cout << " length = " << length << endl;
cout << " area = " << area << endl;
return 0;
}
