Question

Using c++ specific methods:

Practice Problem 2 Write a program which obtains an integer w from the user. Assume that the user will always provide a positive number. The quantity w defines the following shape: OA-OB-OC-OD-w Only when w is greater than 5, have your program request the coordinates (x.y) of a point. Then the program outputs one or two of the following messages: The point is on or inside the yellow (upper) triangle" The point is on or inside the green (lower) triangle" The point is outside of the two triangles" When the point is the origin (0,0), the program should output: The point is on or inside the yellow (upper) triangle" The point is on or inside the green (lower) triangle

Answer 1

int w; cout << "Enter value of w: "; clang version 7.8.9-3-ubuntu. 18.04.1 (tags/RELEASE 9 clang++-7 -pthread -o main main.cpp 10 main Enter value of w: 5 Enter point x and y (separate by space): 2 3 The point is on or inside the upper triangle while(w < 5) ( 12 13 14 15 16 17 18 19 20 21 cout << "Invalid value.

#include <iostream>
#include <cmath>


using namespace std;

int main() {
        int w;
        cout << "Enter value of w: ";
        cin >> w;

        while(w < 5) {
                cout << "Invalid value. Enter w again: ";
                cin >> w;
        }

        int x, y;
        bool found = false;
        cout << "Enter point x and y (separate by space): ";
        cin >> x >> y;

        if(x >= 0 && y >= 0 && (x + y) <= w) {
                cout << "The point is on or inside the upper triangle." << endl;
                found = true;
        }
        if(x <= 0 && y <= 0 && (abs(x) + abs(y)) <= w) {
                cout << "The point is on or inside the lower triangle." << endl;
                found = true;
        }

        if(!found) {
                cout << "The point is outside of the 2 triangles." << endl;
        }
}
