Use std::log Function to Calculate Natural Logarithm of the Given Numberstd::log family of functions are also provided in <cmath> to calculate various logarithms for the given numerical values. std::log function computes the natural logarithm, and similar to the previous functions, it has multi...
Use thestringstreamClass to Conduct Input/Output Operations on String Streams in C++ There are generally three types of STL stream-based I/O library classes: character-based, file, and string. Each of them is usually utilized for scenarios best suited to their properties. Namely, string strings...
When we use the Linux or UNIX operating system, we need to include “unistd.h” header file in our program to use thesleep ()function. While using the Windows operating system, we have to include “Windows.h” header to use the sleep () function. So in order to write a cross-platfor...
A possible solution can be to implement, for example, a RAM test on a part of the RAM that is currently not in use, while the application is temporarily redirected to use another part of the RAM that does not overlap with the tested area. 4.2 No co...

More practically, it is more expensive to use sort or find to get an element in a list container with the generic algorithms than to do the same operation on a vector. As a result, the list container type provides its own class methods, which are more efficient than the generic algo...
Thus, we go for make files and we use to make a tool to build the project and generate the executable. We have already seen various parts of a make file. Note that the file should be named “MAKEFILE” or ‘makefile’ and should be placed in the source folder. ...

Heap variables that could be put on the stack (like a new at the beginning of a block and a delete at the end). Passing types by const& when it would be faster to pass them by value. Use of Qt containers in C++11 range-based for loops which implies a deep copy. ...
