Here are my C++ programming instructions: Write a program that mimics a calculator. The program should take as input:Two floating-point numbersThe operation to be performed (+, -, /, *).

Here are my C++
Write a program that mimics a calculator.
The program should take as input:
Two floating-point numbers
The operation to be performed (+, -, /, *).
It should then output the numbers, the operator, and the result.
Additional notes:
Format your output to two decimal places.
For division, if the denominator is zero, output an appropriate message. The message should contain the word "error"
Here's what I have so far:
#include <iostream>
using namespace std;
//declare the main function
int main()
{
//declare the variables
char op;
float numb1;
float numb2;
//Prompt the user to input two values to be calculated.
cout <<"Please input two values that will be calculated: ";
cin >> numb1 >> numb2;
//Prompt the user to input the mathematical operattor that will be used.
cout <<"Please input the operator that will be used: ";
cin >> op;
cout << fixed << showpoint << setprecision(2);
switch(op)
{
//If the operator chosen is "=", then
case '+':
cout << numb1 << " + " << numb2 << " = " << numb1 + numb2;
break;
//If the operator chosen is "-", then
case '-':
cout << numb1 << " - " << numb2 << " = " << numb1 - numb2;
break;
//If the operator chosen is "*", then
case '*':
cout << numb1 << " * " << numb2 << " = " << numb1 * numb2;
break;
//If the operator chosen is "/", then
case '/':
if (numb2 == 0)
cout <<"ERROR! Dividing by 0 isn't allowed!";
else
cout << numb1 << " / " << numb2 << " = " << numb1 / numb2;
break;
//If the operator is not +, -, *, or /, then the following error message will be displayed.
default:
cout <<"ERROR! The operator you have chosen is incorrect!";
break;
}
return 0;
}
My problem is, I can't figure out where to put the cout << fixed << showpoint < setprecision(2); command line. Everytime I place it in, I get an error message telling me that setprecision wasn't a declared variable in my program, so I can't use it. can someone help me to fix that?
