Write a recursive function named multiply that takes two positive integers as parameters and returns the product of those two numbers (the result from multiplying them together). Your program should not use multiplication - it should find the result by using only addition. To get your thinking on the right track: 7 * 4 = 7 + (7 * 3) 7 * 3 = 7 + (7 * 2) 7 * 2 = 7 + (7 * 1) 7 * 1 = 7 So, 7 * 4 = 7 + (7 + (7 + (7))) The file must be named: multiply.cpp

Solution:
#include<iostream>
using namespace std;
//recursive function multiply
int multiply(int m, int n)
{
int result;
if (n == 1)
result = m;
else
result = m + multiply(m, n-1);
return(result);
}
//main function
int main()
{
int a, b;
cout<<"Enter the value of a and b: ";
cin>>a>>b;
cout<<"Result of multiplication is: "<<multiply(a, b);
return (0);
}

C++ write a function named subtract that takes two integers as parameters and returns the result of subtracting the second number from the first. i.e. int1 - int2 Change subtract to have default arguments for its two parameters. Pick whatever non-zero numbers you would like. Write a prototype for subtract before main so the program runs without error. I cant figure out the part where you pass no parameters, I've tried to set defailt values for the parameters but it...

Write a java recursive method digitMatch that takes two nonnegative integers as parameters and that returns the number of digits that match between them. Two digits match if they are equal and have the same relative position starting from the end of the number (i.e., starting with the ones digit). In other words, the method should compare the last digits of each number, the second-to-last digits of each number, the third-to-last digits of each number, and so forth, counting how...

Write a function named words_in_both that takes two strings as parameters and returns a set of the words contained in both strings. You can assume all characters are letters or spaces. Capitalization shouldn't matter: "to", "To", "tO", and "TO" should all count as the same word. The words in the set should be all lower-case. For example, if one string contains "To", and the other string contains "TO", then the set should contain "to". The file must be named: words_in_both.py...
