Q1. Write a program that will take input of two numbers from user and will show result of addition, subtraction, multiplication, division and remainder.

Program Code:

#include <iostream>

#include <conio.h>

using namespace std;

int main()

{

float x,y,z;

      cout<< "Enter a Number: ";

cin>> x;

cout<<"Enter another Number: ";

cin>>la;

cout<<"Enter the grade in ODE ";

cin>>ode;

cout<<"Enter the grade in CAD ";

cin>>cad;

y=(cf*3+isl*2+wp*2+ap*4+cal*3+lca*4)/18;

cout<<"The Spga in 1st Semester is "<<y<<endl;

z=(bme*3+edc*4+ems*4+ode*3+la*3+cad*1)/18;

cout<<"The Spga in 2nd Semester is "<<z<<endl;

x=(y+z)/2;

cout<<"The Cgpa is "<<x<<endl;

      getche ();

      return 0;

}

Program for Calculator of arithmatic operation:

#include <iostream>

#include <conio.h>

using namespace std;

int main()

{char operation;

int a,b;

      cout<<"Enter first Number: ";

      cin>>a;

      cout<<"Enter second Number: ";

      cin>>b;

      cout<<"Enter an operation arithmatic operation do you want: ";

      cin>>operation;

      switch (operation)

      {
