Updating!!

[GeorgEy5]

Hey, could any one possibly help me with;

updating say, a users weight.?

[MrHutch]

Feed them lots of chocolate?

You'll need to provide a bit more context and, preferably, a bit of code as well.

[GeorgEy5]

Haha!

im creating a BMI calculator which i need to display and also to update the users weight.

im using
if (myChoice ==2) {

}
im just uncertain on what code to use to make this work

[MrHutch]

What do you want if choice 2 is entered?

Do you want the user to enter a new weight? Or a weight to be calculated from some existing variables? Or something else?

[GeorgEy5]

oh yeah sorry.

I want the user to be able to enter a new weight

[MrHutch]

Something like this, then?

if( choice == 2 )
{
    std::cout << "Enter new weight: ";
    std::cin >> weight_lbs;
    std::cout << "New weight is " << weight_lbs << "lbs\n";
}

Assuming that weight_lbs has already been declared. Note, there's no validation there, either. There's nothing to stop the user from typing 'bananas' and the program accepting it.

[GeorgEy5]

okay thank you for that. i'll try it out!

thanks again!
