Introduction In this i have made use of recursion to calculate x to the power n #include <stdio.h> main() {
C Program to solves linear programming problem or LPP by "SIMPLEX" and "DUAL SIMPLEX" method. The code Simplex Method Code #include <stdio.h> #include <conio.h> #define INFINITY 999 #define N 3
Linked Lists Implementation ... #include<stdio.h> #include<conio.h> #include<malloc.h> void insertafter(struct node ** ,int ,int); void insertatbeg(struct node ** ,int ); void add(struct node ** ,int); void search(struct node **,int);
WHAT IS A UNION A union, is a collection of variables of different types, just like a structure. However, with unions, you can only store information in one field at any one time. You can picture a union as like a chunk of memory that is used to store variables of different types. Once a new...
Mostly people are using this algorithm to compute matrix multiplication: #define n 1000 int main() { int a,b,c; c=0; for( i=0;i<n;++i) {
Article is originally written by Zeeshan Amjad Introduction Here I am going to give a detail about Recursion in C++. Definition: Recursion is the process where a function is called itself but stack frame will be out of limit because function call will be infinite times. So a termination...
Most of the people working on Linux must have used the basic command 'ls'. I use it many times a day. It is a very useful command when it comes to displaying the contents of a directory and their properties. For those few who have still not used 'ls' its high time now, go to its man page, study it...
As the topic says, self printing programs are nothing but they reproduce themselves as output. Such programs are referred as Quines from the name of the logician Willard van Orman Quine who introduced the concept. I said an 'Ah!!!' when I heard about Quines for first time, spent more hours to...
Dev-Cpp is an application which is used to code and run programs in C/C++. It has its variations but none of them come with a pre-installed graphics library. So if you are switching from some primitive editor like TurboC to Dev-Cpp (which follows ANSI specifications correctly) and try to write the...
Processes are the primitive units for alocation of system resources...Each process have their own address space and usually one thread of control. The process which makes another process is called the parent and the process which it makes is called a child process..As we know every process have its...
If you are an experienced C/C++ programmer then you must have definitely observed some weird behaviors of code in certain situations. These weird behaviors can be due to various reasons but most of them are because of stack corruption. For all those who have no idea about what stack corruption is,...
There are certain situations where you may want to limit your process's use of system resources like CPU or may want to put certain limitations on things like number of open file descriptors, maximum memory your process can allocate for its data etc. You may use commands like ulimit, sysconf etc to...
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...
A friend of mine who is learning to program in C, was having diffculty in writing a program to find the sum of all the prime numbers between a specified limit (in her case 3-60). I helped her out with the program, and I thought I'll post it here which might help others. /* ** Program to...
A Program to check whether entered matrix is symmetric or not. #include<stdio.h> #include<conio.h> main() { int a,at,k,i,j,m,n; clrscr(); printf("enter the order of matrix"); scanf("%d %d",&m,&n);
Stack memory Let's suppose there is nothing on the stack to begin with. One of the functions either the calling function or the called function depending on the calling convention would start a stack. Lets take a very simple C / C++ program to see how things would work. int func(int i) {...
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...
During C programming, file operations are pretty common. And when you are writing programs in C on Linux, two familiar terms related to file operations are File Pointers and File Descriptors. We know both are different, but what are they? This article will focus on understanding what are file...
Most of the newbie programmers are fascinated by the term 'hacking' or 'cracking'(to be precise). Generally, they see some weirdly written code (that may visually seem like a painting to any new programmer) and start dreaming of the developer who has written the code as god of programming or...
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...
