In both the above answers the op overloads should be using a const ref as input. You should have a (private) ctor that makes the matrix from the data, and should use RVO in the return.

Why we follow top down approach in C-language and bottom up approach in C++?Explain in detail.

random viewer

• Jun 11th, 2012

The question is wrong. In most cases, regardless of the language, top down is the better approach. Actually TDD forces this. You must first know what you want, that is, how the client code will use it, before you can design it. Always top down. Just remember that.

2^3 = 8 , agreed -> but 1 will be the parent process , so the child processes is 7

 The idea behind inline functions is to insert the code of a called function at the point where the function is called. If done carefully, this can improve the application's performance in exchange for increased compile time and possibly (but not always) an increase in the size of the generated binary executables.

An Inline function is a function that is expanded in line when it is invoked. That is compiler replaces the function call with the corresponding function code.. :)
