Difference between bool check=true; and bool check=1;

Answer 1

As quoted from MSDN (https://msdn.microsoft.com/en-us/library/c8f5xwh7.aspx):
"In C++, a value of type bool can be converted to a value of type int; in other words, false is equivalent to zero and true is equivalent to nonzero values. In C#, there is no conversion between the bool type and other types. For example, the following if statement is invalid in C#"

In C/C++, the value of bool and int are convertible but not in C#. So the following statements:

C++:
bool check = true; // or 1
if (check)
cout<<"This is acceptable for both true or 1 in c++";

but,
C#:
int x = 123;

// if (x) // Error: "Cannot implicitly convert type 'int' to 'bool'"
{
Console.Write("The value of x is nonzero.");
}

Hope this helps.
