这个是出什么问题了

//carrots.cpp -- food processing program
//uses and displays a variable

#include <iostream>

int main()
{
    using namespace std;

    int carrots

        carrots = 25
        cout << "I have"
        cout << carrots;
        cout << "carrots.";
        cout << endl;
        carrots = carrots - 1;
        cout << "Crunth,crunth. Now I have " << carrots << "carrots." << endl;
            return 0;
}
