C++ Add, Subtract, Multiply, Divide and Modulus of Two Numbers | C++ Code

Method#1
#include<iostream>
using namespace std;
void main()
{
int a=5. b=4,sum,pro,sub,div,mod; //Initializing variables

sum=a+b; //Adding Two Numbers

pro=a*b; //Multiplying numbers and storing result in variable 'pro'

sub=a-b; //Subtracting Two numbers

div=a/b; //Dividing Two Numbers

mod=a%b; //Finding Remainder of Two Numbers

cout<<"==========================================="<<endl;

cout<<"Sum: "<<sum<<endl;  //Displaying the Result of sum

cout<<"Product: "<<p<<endl; //Displaying the Result of  product

cout<<"Subtraction: "<<sub<<endl; //Displaying the Result

cout<<"Divsion"<<div<<endl;

cout<<"Remainder: "<<mod<<endl; //Displaying Modulus of Two numbers
