C++ Inline和Normal的區別用法及代碼示例

// C++ program to demonstrate inline function
// Importing input output stream files
#include <iostream>
using namespace std;
// Method 1
// Inline function
// To multiply two integer numbers
inline int multiplication(int x, int y)
{
    // Returning the product of two numbers
    return x * y;
}
// Method 2
// Main driver method/function
// Execution begins here
int main()
{
    // Print and display the multiplication resultant number
    // with usage of above created multiplication() inline()
    cout << "Multiplication ( 20 , 30 ):"
         << multiplication(20, 30) << endl;
    return 0;
}

// Importing input output streams
#include <iostream>
using namespace std;
// Method/Function
// To get square of integer number been passed
int square(int s)
{
    // Returning the square of number
    return s * s;
}
// Method
int main()
{
    // Calling the square() method/function
    // over randoM value N
     
    // Say N = 5
    // Display message only
    cout << "Enter number to compute its square : 5 " << endl;
    // Calling the above square() in main()
    // and print/display on the console
    cout << "Square is : " << square(5) << endl;
   
  return 0;
}
