Characteristics of Computer

Characteristics of Computer Lets just enlist the characteristics of computer Accuracy Diligence Speed Remembering power Versatility Automatic No IQ No Feelings Accuracy As we already know that computer is an electronic machine. The name of this machine " Computer " explains much of the details about this heading. Since it is a computing device, it provides maximum accurate answer. Although it is an electronic device still it's calculated answer is not absolute accurate sometimes because it is a human product and also the input is given by the human beings which may be wrong. Now the crux of the above discussion that you can write in any exam is that computer is a calculating device that provides the most accurate answer of different problems as compared to humans. Diligence Since computer is a machine, a non living thing, it can work for hours and hours without getting tired. This is the beauty of Computer, humans can't stand against...

How to take input in C++

Hello azumavengers and welcome to my blog. Today we will talk about taking input in C++ . How to take input in C++ There are different ways of taking input for the variables or objects.  Usually programs take input from keyboard or from files on disks or from data base. Right now filing and data base is not our concern so we will discuss about the input given using keyboard. For taking input from user we use extraction operators ">>". The reserved word used for taking input in cin. Actually cout and cin are the variable instances of the classes declared in iostream. cout is the variable of type ostream and cin is the variable of type istream. Let's see an example #include <iostream> using   namespace  std; void  main() { int   var1  = 0; //integer  cout  <<  "Enter an integer = " ;//displays Enter an integer = cin  >>  var1 ;//waits for user to enter value...
