C++11 supports range-based for loops. This is a very convenient feature, can save quite a lot of code. The following code makes it easy to traverse the elements in the vector and print them out: Std::vector Int_vec; Int_vec.push_back

People who know a little about C programming know that text files and binaries are stored in 0,1 on a computer, so how are the two different? For programmers, text files and binaries are statements that indicate how you should open the file
