Wondering if we can swap an integer and a floating number in a single function with generics.. Do you know how to do that?

If anyone is getting an error with this, it's probably because you named the "swap()" function in all lowercase. There is already a "swap()" function defined in the std library that you imported using the namespace so it will cause an ambiguous function overload error.

@@Kanha0321 nothing wrong with it, you just need to name your functions uniquely, so that you don't clash with std. I've not had any problems, just had to name my functions following a pattern so that there are not any clashes.

I just ran into an issue on this one where I defined my swap function with all lowercase (since functions are camel case and classes are camel starting with an upper, so I thought you made a mistake). Turns out there's a built in swap function that's already generic (and it was getting called without prepending std:: since I included the std namespace globally). So when I used the generic type in my function definition it thought I was overloading it to be generic AGAIN so it had no clue which one to use... Interesting little bug that sent me down a rabbit hole lol

*Generics are a way to make functions that work for different variable types. * put "template" (or any other name for your template) in the line above your function, and use that name as the type of the variables in the function. *Although it is not required, it is best practice to specify the type of variables when you call the function. For example, instead of Swap(a, b); You should do Swap(a, b); Thank you for the video, Saldina!

The function swap is only partly generic imo It swaps two *int* variables or *two* char variables Real generic would have to be able to handle _more_ than *one* type, in the _same_ call So int main(){ int a=5; char b = 'b'; cout

Hi Saldana - following your advice for best practice I moved the Swap() definition below main(), and placed a Swap() declaration above main(). However, things started going a bit pear-shaped when it came to adding template. Unless I place the template line immediately above both the Swap() definition and declaration I get a compiler error. But the solution feels wrong as I am duplicating the same line of code. Is it correct to write the template line twice, or is there a better way? Cheers. P.s There seem to be many very clever people teaching coding on YT, but imo you have by far the best teaching style - you always break the problems down into easy to understand chunks, so thank you!
