Mathematical Operations (+,-,*,/)

All mathematical operation can be solved in one place use of switch case for user friendly solution 

user can Add,Sub, Div and multiply

Source Code :-

#include<iostream.h>

#include<conio.h>

void main()

{ clrscr();

  float a,b,add,sub,mul,div,choice;

  cout<<"Mathematical Operation  By   TARUN RAWAT  \n";

  cout<<"\nEnter Two Values for operation \n "; cin>>a>>b;

  cout<<"Enter your choice (type 1,2,3,4) \n";

  cout<< " 1 - Addition \n 2 - Subtract \n 3 - Division \n 4 - Multiply \n";

  cin>>choice;

  if(choice==1)

    { add =a+b;  cout<<"\n Addition is "<<add;}

  if(choice==2)

    { sub=a-b;   cout<<"\n Subtraction is "<<sub;}

  if(choice==3)

    { div=a/b;   cout<<"\n Division is "<<div;}

  if(choice==4)

    { mul=a*b;   cout<<"\n Multiplication is "<<mul;}

getch();

}
