gnuplot-Download Gnuplot is a portable command-line driven graphing utility for Linux, OS/2, MS Windows, OSX, VMS, and many other platforms. The source code is copyrighted but freely distributed (i.e., you don’t have to pay for it). It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as web scripting. It is also used as a plotting engine by third-party applications like Octave. Gnuplot has been supported and under active development since 1986. Gnuplot supports many types of plots in either 2D and 3D. It can draw using lines, points, boxes, contours, vector fields, surfaces, and various associated text. It also supports various specialized plot types. Gnuplot supports many different types of output: interactive screen terminals (with mouse and hotkey input), direct output to pen plotters or modern printers, and output to many file formats (eps, emf, fig, j

Introduction of Data Structure and Algorithms

what is data structure ? data structure is a particular way of storing and organizing data in a computer so that it can be used efficiently. or data structure is an arrangement of data in a computer's memory. type of data structure what is algorithm algorithm is a step-by-step procedure for calculations. Algorithms are used for calculation, data processing, and automated reasoning. Data Structure + Algorithms = program Data structures and algorithms are vital elements in many computing applications. When programmers design and build applications, they need to model the application data.

Switch case in perl

first download  Switch  then use use Switch; $var =1; switch($var){    case 1            { print "1\n";}    case 2            { print "2\n";}    case 3            { print "3\n";}    case 4            { print "4\n";}    case 5            { print "5\n";}    else              { print "6\n"; } } or  use Switch; $var = 10; @array = (10, 20, 30); %hash = ('key1' => 10, 'key2' => 20); switch($var){    case 10                   { print "number 100\n" }    case "a"                   { print "string a" }    case [1..10,42]        { print "number in list" }    case (\@array)        { print "number in list" }    case (\%hash)          { print "entry in hash" }    else                         { print "previous case not true" } } if not use Switch cpan then error

How to delete the array in C and C++

  In C array[0] = '\0'; In C++ array = new int[5]; // Declare an array delete [ ] array;   // Delete an array array = 0;      // Clear a to prevent using invalid memory reference

How to copy and paste in cmd

ALT+SPACE+E+K <-- for copy . and ALT+SPACE+E+P <-- for paste. or 1. for copy 2. for paste ->  right click

too many types in declaration error in c

You have to put ; behind the struct declaration:   struct tnode { int data ; struct tnode * left ; struct tnode * right ; }; // <-- here
