ubuntu下学习c++(输出定义变量）

2022.6.11 学习cout，cin的使用方法以及变量的定义。

#include<iostream>

int main(void)
{
        using namespace std;

        int carrots;

        carrots = 25;
        cout << "l have ";
        cout << carrots;
        cout << " carrots";
        cout << endl;

        carrots = carrots -1;
        cout << "Now i have " << carrots << " carrots" << endl; 

        return 0;
}

输出结果：

#include<iostream>

int main(void)
{
        using namespace std;

        int carrots;
        cout << "How many carrots do you have?" << endl;
        cin >> carrots;
        cout << "Here two more.";
        carrots = carrots + 2;
        cout << "Now you have " << carrots << " carrots." << endl;

        return 0;
}

输出结果：
