simple calculator

[bpedigo]

I am currently taking a class and one of the problems is to make a simple calculator. I have been able to make the code work but the out put isn't what the teacher is looking for. the input should be three float numbers like

25000
625
1

form that the output should be
25000.000000 + 625.0000000 = 25625.0

as you can see he wants six zeros added to some of the out put and one zero added to the last number. I don't know how to do that. Any help would be great.

#include <iostream>
#include <iomanip>


//cout<<fixed<<setprecision(2); this is for my notes olny

using namespace std;

void simple_calculator();

int main()
{
    simple_calculator();
    return 0;
}

void simple_calculator()
{
    int menu_option;
    float frist_number, second_number;
    cout<<"Enter first number:\n";
    cin>>frist_number;
    cout<<"Enter second number:\n";
    cin>>second_number;
    cout<<"Enter a menu option:\n";
    cout<<"[1] Add:\n";
    cout<<"[2] Subtract:\n";
    cout<<"[3] Multiply:\n";
    cout<<"[4] Divide:\n";
    cin>>menu_option;
    switch (menu_option)
    {
    case 1:
        cout<<frist_number<<" + "<<second_number<<" = "<<frist_number + second_number;
        break;
    case 2:
        cout<<setprecision(6)<<frist_number<<" - "<<setprecision(6)<<second_number<<" = "<<setprecision(1)<<frist_number - second_number;
        break;
    case 3:
        cout<<setprecision(6)<<frist_number<<" * "<<setprecision(6)<<second_number<<" = "<<setprecision(1)<<frist_number * second_number;
        break;
    case 4:
        cout<<setprecision(6)<<frist_number<<" / "<<setprecision(6)<<second_number<<" = "<<setprecision(1)<<frist_number / second_number;
        break;
    }
}

You forgot the setprecision flags for the first case of switch. Also, if the precision remains constant, you don't need to respecify.

You forgot to put cout<<fixed;

#include <iostream>
#include <iomanip>


//cout<<fixed<<setprecision(2); this is for my notes olny

using namespace std;

void simple_calculator();

int main()
{
    simple_calculator();
    return 0;
}

void simple_calculator()
{
    int menu_option;
    float frist_number, second_number;
    cout<<"Enter first number:\n";
    cin>>frist_number;
    cout<<"Enter second number:\n";
    cin>>second_number;
    cout<<"Enter a menu option:\n";
    cout<<"[1] Add:\n";
    cout<<"[2] Subtract:\n";
    cout<<"[3] Multiply:\n";
    cout<<"[4] Divide:\n";
    cin>>menu_option;
    cout<<fixed; // <------ put this over here
    switch (menu_option)
    {
    case 1:
        cout<<setprecision(6)<<frist_number<<" + "<<setprecision(6)<<second_number<<" = "<<setprecision(1)<<frist_number + second_number;
        break;
    case 2:
        cout<<setprecision(6)<<frist_number<<" - "<<setprecision(6)<<second_number<<" = "<<setprecision(1)<<frist_number - second_number;
        break;
