(Geometry: distance of two points) Write a program that prompts the user to enter  two points (x1, y1) and (x2, y2) and displays their distance between them.The formula for computing the distance is  √ (x2 - x1)²+ (y2 - y1)² . Note that you  can use pow(a, 0.5) to compute √a.  #Beginner In gcc c++ compiler using namespace std; #include<iostream> #include<cmath> using namespace std; int main() { float x1,y1,x2,y2; cout<< "Enter x1 and y1 :" ; cin>>x1>>y1; cout<< "Enter x2 and y2 :" ; cin>>x2>>y2; float distance=pow((pow(x2-x1,2))+pow(y2-y1,2),0.5); cout<< "The distance between the two points is :" <<distance; return 0; } copy Output Enter x1 and y1 :1 9 Enter x2 and y2 :3 -5 The distance between the two points is :14.1421 [Program finished] Need of Programmer Need of Programmer
