Answer 1

Joel -Mr.Twister , to give you a start, here is how the code could begin. all the rest is up to you and your turn...

int num1, num2, ans;
double res;

cout << "Use Any Function \n Type-1 for add: \n Type-2 for sub: \n Type-3 for mul: \n Type-4 for div: \n";
cin >> ans;
cout << "Okay first number: " << endl;
cin >> num1;
cout << "Write second number: " << endl;
cin >> num2;

if(ans==1){
res = num1 + num2;
}
.......
cout<<"Your answer is: " << res ;

Answer 2

What kind of urgency is there ?

and also define what do you mean by "repetitive to use"

do you mean making it reusable or making it loop till user doesn't want quit ?

your question is unclear

Answer 3

Joel -Mr.Twister , before proceeding with your code, you should think about avoiding repeated code. you are using a whole bunch of variables, different ones for different operations, but all have the same data type. from my point of view, you need not more than 4 variables:

- numerical input 1
- numerical input 2
- operator to use
- result

also you don't need to have multiple input routines, you only need to have 2 for the both numerical values and one for the operator.
Applying this to your code will greatly reduce the size of your program.
Happy coding!

Answer 4

Joel -Mr.Twister Add a do while loop .
