Question

C++ PLEASE. MAKE SURE CODE WORKS BEFORE SUBMITING ANSWER

Create a recursive function that will accept two arguments into the parameters x and y. The function should return the value of x times y. Remember, multiplication can be performed as repeated addition.

7 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4

Answer 1

Code:

#include <iostream>
using namespace std;
double multiplication(double x,double y) //recursive function to calculate multiplication
{
if(x>0) //if x>0 then the function call itself recursively
{
return (y+multiplication((x-1),y)); //function call itself
}
else
return 0;
}
int main() //main function
{
double x,y,result;
cout<<"Enter two numbers"<<endl;
cin>>x; // take input from user
cin>>y;
result=multiplication(x,y); // call multiplication function to multiply 2 numbers
cout<<"Result = "<<result; //print output
return 0;
}

1 3 { } #include <iostream> 2 using namespace std; double multiplication(double x, double y) //recursive function to calculate multiplication 4 5 if(x>0) //if x>0 then the function call itself recursively 6 { 7 return (y+multiplication((x-1),y)); //function call itself 8 } 9 else 10 return 0; 11 12 int main() //main function 13- { 14 double x,y,result; 15 cout<<"Enter two numbers"<<endl; 16 cin>>x; // take input from user 17 cin>>y; 18 result=multiplication(x,y); // call multiplication function to multiply 2 numbers 19 cout<<"Result = "<<result; //print output 20 return ; 21 22

Output:

Enter two numbers 7 4 Result = 28 ... Program finished with exit code 0 Press ENTER to exit console. I
