Continuation of Shell-coding basics..I suggest a glance over it before you start reading this.. Testing We'll be using a simple C program to accomplish our task. test.c // #include<stdio.h> we will not be needing this as we are not using any functions from the C library...Just basic...

The other day, I just had this thought of exhausting the R.A.M. of my ailing, old P.C. in the hopes that it may trigger off a cataclysmic crash which would render it useless :happy: (so that I finally get that brand new mega-system P.C. which I so yearn! :D ) So I set out to write this program...

Suppose a system call was blocked due to some reason (like waiting for a read of some data on terminal) and during this time a signal occurs. Do you know what happens in this scenario? In this article we will discuss the impact of signals on system calls. System calls are different from...

Introduction In computer science a search algorithm is a technique of finding a particular item among a collection of items. Searching for data is the second most common activity (after sorting data) necessary for creating many types of programs. Sequential Search In this technique we...

Type casting is an explicit type conversion requested by the programmer to achieve its objective in the program. During any kind of computations involving various data variables of different data types, leads to the need of typecasting. Syntax used: (Data-type-2)<variable/expression of data...

There are many built in data types in C. But sometimes, the built in data types are not enough to perform the required tasks. In that case, some custom data type can be built to meet the necessary requirements. In this tutorial, the following custom data types are going to be discussed: ...

Format strings are the strings mainly associated with printf's set of instructions (like printf,fprintf etc..) which basically stands for print format.... These functions accept several arguments and put them on the stack..and as a format specifier is noted in the string the function pops the data...

Data files are very essential part of in computer programming. The data we use while programming using the variables of different data types, are unavailable after the program execution. So,there is no way to retrieve the data if we further need. Here comes the necessity of data files. FILE...

Error handling has always been dominantly vital in programming. It has become a bit more sophisticated with the object oriented languages, however even in the system programming language like C, error handling is being offered in its own simple ways. Introduction To swim deep into the...

Pretty sure, one must have used the datatype ‘float’ numerous number of times since the day one has started programming. However, there are many times, when we mishandle floats and doubles, or get unexpected results while using float variables or find ourselves being perplexed while using floating...

As the name suggests, volatile specifier indicates the compiler that the value of the variable is volatile i.e. it can change unexpectedly. But, the question comes why do we need to even specify that a variable value is volatile. The Requirement for volatile specifiers Our compilers...

Pointer Pointer is a declared like a variable, but it's not an ordinary variable, it's a fancy variable, that can store address of the another variable. Pointer is very much useful for allocating memory at run time , that's dynamic allocation. Pointers are said to "point to" the variable whose...
