Program to find line passing through 2 Points in C++
In this problem, we are given coordinates two points A and B on the coordinate plane. Our task is to create a program to find line passing through 2 Points in C++.Problem DescriptionTo find the line, we need to use the equation of the line and put the solution using the coordinates.Let’s take an example to understand the problem−Input: A = (3, 3) B = (6, 1) Output: 2x + 3y = 15Solution ApproachTo find the equation of the line, we will use the general equation of line −ax + by = cThis has to be satisfied by both the points ...

Read MoreComplex Number Multiplication in C++
Suppose we have two strings that are representing complex numbers, we have to parse them and perform complex number multiplication, then return result as a string.So if the input is like “1+-1i” and “1+-1i”, then the result will be “0+-2i”.To solve this, we will follow these steps −aa := a pair of real and imaginary of first complex numberbb := a pair of real and imaginary of second complex numberx := aa.real * bb.real – aa.img*bb.imgy := aa.real * bb.img + aa.img*bb.realreturn the string as “x+yi”Let us see the following implementation to get better understanding −Example#include using namespace std; ...
