If l use two constractor with different type like string and int but both have only one variable this give error or not?

Answer 1

You might want to give a sample code / more info to better illustrate a model of the problem. Is this C++?

Answer 2

You can read this for more information: https://www.csee.umbc.edu/~chang/cs202/Lectures/modules/m04-overload/slides.php?print

Constructors are functions, so they follow the same rules.

The rules applied for C/C++ and Java, maybe C# as well.

Answer 3

normally you have to define the type of the given variable, so you can create 2 Constructors IF the given types differ from each other.

At least this is for Java and I guess it's applicable for C++/C# as well
