JMeter is a desktop application that can be used to perform functional testing and load testing.
While the JMeter application itself is designed as pure Java application, it can be used to perform load testing of any kind of web application, including those that are written in PHP, .NET, etc.
In C and C++ programming, pointers are very powerful.
As we explained in C pointers example article, pointers are variables that hold address of another variable so that we can do various operations on that variable.
Sometimes a programmer can’t imagine writing a code without using pointers, whether it is a simple binary search tree program, or a complex enterprise application.
But, pointers are hard to manage, master, and they can cause many problems if not handled properly.
For example, when not properly used, it can cause core dumps, dangling pointer, null pointer exception, memory leaks, etc.

Sometimes you might have access to an open source application source code but might not have the RPM file to install it on your system.
In that situation, you can either compile the source code and install the application from source code, or build a RPM file from source code yourself, and use the RPM file to install the application.
There might also be a situation where you want to build a custom RPM package for the application that you developed.
This tutorial explains how to build a RPM package from the source code.
