我的第一次编程

1.average：#include<iostream>

using namespace std;

int main() {

double a, b, c;

cout << "请输入第一个数" << endl;

cin >> a;

cout << "请输入第二个数" << endl;

cin >> b;

cout << "请输入第三个数" << endl;

cin >> c;

cout.precision(3);

cout << fixed;

cout << "平均值是" << endl;

cout << (a + b + c) / 3;

system("pause");

return 0;

}

2.temperature：#include<iostream>

using namespace std;

int main() {

double f, c;

cout << "请输入华氏温度" <<endl;

cin >> f;

c = 5*(f - 32) / 9;

cout.precision(3);

cout << fixed;

cout << "摄氏温度为" << c << endl;

system("pause");

return 0;

}
