Question

1. Multiplication and Division using PIC16F

PIC16 is a very basic microcontroller with the capability of limited arithmetic and logical operations. It has dedicated arithmetic instructions for addition, subtraction, increment and decrement. If we want to perform a multiplication and division operations then we need to write a program for it. Multiplication is nothing but repeated addition. However, division can be implemented using repeated subtraction. This mini-project presents assembly or C language program for the multiplication and division of two 8-bits numbers with the illustration of 3 different cases.

The Multiplication can be illustrated using the following cases:

Case 1:02H x 03H = 06H

Case 2: A7H x F2H = 9DDEH

The Division can be illustrated using the following cases:

Case 1: 1Bh÷02h= 0Dh Remainder = 01h

Case 2: FFh÷05h= 33h Remainder=00h

Case 3: 07÷A2h= 00h Remainder=07h

Answer 1

#include <iostream>
using namespace std;

int main ()
{
int n1,n2,result;

cout <<"First Hex Number :";
cin >> hex >> n1;

cout << endl;

cout <<"First Hex Number :";
cin >> hex >> n2;

result = n1*n2;


cout << hex << n1 << endl;
cout << hex << n2 << endl;
cout << hex << result<< endl;

return 0;
}

This could be easy in c++ then c language once check it out

The same will be you can use for division also
