/*question number 1*/ int z,x=5,y=-10,a=4,b=2; z = x++ - --y * b / a;What number will z in the sample code above contain? Choice 1 5 Choice 2 6 Choice 3 10 Corrected by buddy by running the program Choice 4
Two of my friends faced a problem with writing a program which finds the LCM(Lowest Common Multiple)/GCD(Greatest Common Divisor) of two positive integers, so I helped them out by writing two functions for each. I thought many others might be having the same problem. So here are the functions:...
I worked for a long time for this article. This program is tested on Sun-Solaris system using gcc compiler. In market, there are a lot of tools for detecting the memory leaks. Here I made a program which has to include in your source file and it will tell the desired informations to find where...
Program for singly circular linked list which inserts, deletes, searches .... data in it #include <stdio.h> #include <conio.h> #include <stdlib.h> #include <string.h> /***** Structure template *****/ struct list{
The below code is a calculator in plain C. It does not take into account the operability of bodmas but just one operation at a time. The main thing in the source code below in the scanf which scans the input as number symbol number just as in case of normal calculator. #include<stdio.h> ...
A simple code of Http-Web-Server in C done by a beginner level programmer. Please suggest if you liked it and lets make it better !! Hows that!!! The Code #include<stdio.h> #include<string.h> #include<arpa/inet.h> #include<netdb.h> #include<sys/types.h> #include<sys/socket.h>
InFix to PostFix Introduction Infix Expression : Notation in which the operator separates its operands. Eg (a + b) * c. Infix notation requires the use of brackets to specify the order of evaluation. Postfix Expression :
Calculating the factorial of a number is a basic excercise while learning to program in C, many of us have done it iteratively, it can also be done recursively. I am posting both iterative and recursive versions below. /* Recursive Version */ unsigned int recursive_factorial(int n) ...
The article discusses about all the number formats viz Binary, Decimal, Octal, Hex and BCD (Binary coded decimal) and conversion from Decimal to Binary, Octal and Hex and also the reverse conversion. Binary A numbering system based on 2 in which 0 and 1 are the only available digits. ...
1. #include<stdio.h> #include<conio.h> main() { int a,i; for(i=0;i<3;i++) a=i++; for(i=0;i<3;i++)
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...
In this article, I'll present some interesting 'C' problems for which I will not provide the answer. If you are not bale to solve any problem, then just leave a comment here so that everybody is benefited when the problem is discussed. Problems 1) Will the program execute without any problem?...
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...
Introduction After a long hiatus, I am back. Months without programming and then finally I got some time on my hands. So I set out to code the Huffman's Data Compression Algorithm. And the result is here! :D The code is well-commented and I hav given some additional documentation. Also, I...
Introduction Itís my first post here. I will discuss on Date & Time Management Functions of C. Though if someone is only interested about getting the time and date, then it can be done by some trivial function but the goal of this detail discussion is understanding the bios as well as...
Refer to the recent articles on Understanding File Handling Functions in C & Understanding Advance File Handling Functions in C Opening A File Before we can write information to a file on a disk or read it, we must open the file. Opening a file establishes a link between the program and the...
How to make your program to be fast. 1. Use Pre Increment or Pre Decrement in place of Post Increment or Post Decrement operator. i.e. use ++i or --i in place of i++ or i--. Because ++i operator take increment and save it i.e. One CPU Instruction is required for it. and in case of i++...
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...
The code to swap two variables using macro expansions #include<stdio.h> #include<conio.h> #define SWAPE(x,y) int t;t=x;x=y;y=t; main() { int a,b;
Function pointers are pointers that can hold the address of a particular type of functions. These pointers, once initialized can be used to call the function whose address they are pointing to. Declaring Function Pointer A function pointer can be declared in following way : <return type of...
