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; }
