c中將數組傳遞給子函數

Here, we have to define a Non-Member Function, in which we have to pass an Object to the class in C++ programming language.

在這里，我們必須定義一個非成員函數，其中必須將一個Object傳遞給C ++編程語言的類。

What we are doing in this example?

在此示例中我們正在做什么？

• We declared a class named Number that has a private data member named num.

  我們聲明了一個名為Number的類，該類具有一個名為num的私有數據成員。

• We define a Non Member function named myFunction(), that will take two parameters 1) object to class Number and 2) an integer variable number.

  我們定義了一個名為myFunction()的非成員函數，該函數將使用兩個參數：1)對象為Number類，以及2)一個整數變量number 。

Using the example, We have to supply a number (from the main() function) to the class's data member using a Non-Member Function.

使用示例，我們必須使用非成員函數為類的數據成員提供一個數字(來自main()函數)。

Program:

程序：

#include <iostream> using namespace std;class Number {private:int num;public:void setNum(int n){num = n;}int getNum(void){return num;} };//a non member function void myFunction(class Number N, int number) {//calling setter function and asigning the number N.setNum(number) ;//calling getter function and printing the value cout<<"The value is: " << N.getNum() << endl; }//Main function int main() {//local variable of the main int num;//object to Number class Number objN;num = 10;//supplying this 'num' to the class by passing //the name to the class in a non memberfunctionmyFunction (objN, num);return 0; }

Output

輸出量

The value is: 10
