When a process terminates abnormally it usually tries to send a signal indicating what went wrong. C programs (and UNIX) can trap these for diagnostics. Also user specified communication can take place in this way. Signals are software generated interrupts that are sent to a process when a...

Do while loops Do while loops are special kind of loops that are used to execute statements repeatedly in some programming languages including C. The do while loop is quite similar to the while loop but the main special thing about Do While loops are that they evaluate conditions at the bottom...

For Loops ‘For loops’ are more concise and special kind of loops that are used to execute statements repeatedly in some programming languages including C. The For loop structure is quite different from while loops as well as do while loop structures which we had a look in previous articles. ...

In this tutorial we’ll be learning about LOGICAL operators in C , What are they and How they can be used. These are also a fundamental part of C programming Language, and You’ll find them in almost every useful code using conditions. Note : C Generally denotes 1 for True and 0 for False. (While...

Looping While writing our C programs we might feel a need to execute similar or same set of instructions multiple times , for eg: Printing numbers from 1 to 100 on the screen , This task without the use of looping could be very tedious and make would make the code absolutely not redistributable...

I am doing C programming from a couple of years ago and finally I convinced myself and grabbed all my guts to write an article on Pointers. Now, one could easily question Why? Basically, Pointers are the most useful part of C and usually the most difficult to understand. Note: I don't want to...

The while loop is a statement used in some programming languages (including C) to execute code repeatedly, this allows a programmer to execute a set of instruction multiple times until a condition is met. It is one of the simplest looping structure in C and basically follows the following...

This time we checked Apache HTTP Server with PVS-Studio. As we had expected, we found errors there. The errors are few. We expected this either. Other developers come across this situation too while testing PVS-Studio on their projects. Unfortunately, the first conclusion you would like to draw...

Loops are the basic logic building structures in computer programming. It is a way of executing statement(s) repeatedly in specified times, which is termed as iteration. Here different types of loops in C language will be discussed. All of them have same goal, but their way of working is...

We will discuss the concept of Macros. A Macro is a name given to a piece of code or to a value. Whenever the macro is used in the code, it is replaced by its value at the very first stage (preprocessing stage) of compilation process. They are defined using '#define' directive. For...

In this article we'll be learning how we can improve our C code by using Macros instead of functions. How simple functions can be converted into macros to save on some CPU instructions. Some basic knowledge of C and a little bit Assembly is considered as pre-requisites. The Code We'll be...
