How a computer works?

A computer is an electronic device which consist of four basic unit:

  1. Input
  2. processing
  3. output
  4. storage
Basically a computer cannot understand any thing by it's self because it is not too much intelligent you have to teach it to bring it in working order.
So, for this purpose we give it a set of instructions through proper languages called programming language. Now a programming is used to make it valuable.
programming languages are of two types;

  1. Low level language
  2. High level language
 LOW LEVEL LANGUAGE;
                                                It is a language which is directly understandable by computer system and it is very hard to learn and use.
HIGH LEVEL LANGUAGE;
                                               It is language which is easy to learn and nearly close to English but this language is not understandable by computer so there is a translator embeded in it.
After programming a computer become useful.

Here are some video lectures for it.
We will furthure describe it in coming blogs.

OOP Assignment 3 helping materials

 Following is the code that will help you in the assignment for the addition of the arrays using operator overloading and returning an object. #include<iostream> using namespace std; int num; struct add {     int ar[20]; }; add operator+(add &a1,add &a2) {     add a3;     for(int i=0;i<num;i++)         a3.ar[i]=a2.ar[i]+a1.ar[i];     return a3; } int main() {     add a1,a2,a3;     cout<<"How many elements to be stored (max 20) : ";     cin>>num;     cout<<"Enter elements of array a1 : ";     for(int i=0;i<num;i++)         cin>>a1.ar[i];     cout<<"Enter elements of array a2 : ";     for(int i=0;i<num;i++)         cin>>a2.ar[i];     a3=a1+a2;     cout<<"Addition of two arrays : ";     for(int i=0;i<num;i++)   ...

Square root Algorithm in C++

 Here is the way you can find the square root of any number by writing your own code in c++.  #include<iostream> using namespace std; double sqrt(double num){ double stop_condition = 0.00000001; double guess = num/2; while((guess-num/guess) > stop_condition){ guess = (guess+num/2)/2; } return guess; } int main(){ double num = 4; cout<<"The result is: "<<sqrt(num)<<endl; return 0; }
