It is obviously give 0.2 answer ...
Code- #include <iostream>

The floating-point arithmetic in most computer languages is based on binary fractions (1/2, 1/4, 1/8, 1/16, ...) and not decimal fractions (1/10, 1/100, 1/1000, 1/1000,...)there is no ActionScript Number that is exactly equal to 0.1 because it require an infinite number of binary fractional bits.

Visual Studio uses partial classes to separate auto-generated code from user-generated code. Example:Let us consider that visual studio creates a file called Form1.Designer.cs which holds the designer-related, auto-generated code. So in both Form1.cs and Form1.Designer.cs the Form1 class is declared as partial and the compiler joins them into one.

Partial class
where do you use partial class ? Explain with real time scenario of the usage ?
Sandhya.Kishan
- Mar 12th, 2012
Splitting the class into multiple files is called as partial class.The compiler treated the files as different classes but during compilation these files will be treated as a single class. Example:If...
Int i;void main(){ int j=100,k; cout

Compilation fails, why because it does not have proper syntax and structure.

In Java it is not possible to overloading OPERATOR such as +/-/* etc. We can do that is C++. In Java there won't be any friend function. ...That is why we can't use friend function overloading in Java
