函数的常见样式
常见的函数样式有4种
1. 无参无返
2. 有参无返
3. 无参有返
4. 有参有返
#include<iostream>
using namespace std;
//函数常见样式
//1、无参无返
void test01()
{
cout << "this is test01" << endl;
}
//2、有参无返
void test02(int a)
{
cout << "this is test02 a = " << a << endl;
}
//3、无参有返
int test03()
{
cout << "this is test03" << endl;
return 1000;
}
//4、有参有返
int test04(int a)
{
cout << "this is test04 a = " << a << endl;
return a;
}
int main(){
//无参无返函数调用
test01();
//有参无返函数调用
test02(100);
//无参有返函数调用
int num1 = test03();
cout << "num1 = " << num1 << endl;
//有参有返函数调用
int num2 = test04(10000)
cout << "num2 = " << num2 << endl;
system("pause");
return 0;
}
