Given four integers A, B, C and D which represents the four angles of a Quadrilateral in degrees. The task is to check whether the given quadrilateral is valid or not.
Examples:
Input: A = 80, B = 70, C = 100, D=110
Output: ValidInput: A = 70, B = 80, C = 130, D=60
Output: Invalid
Approach:
A Quadrilateral is valid if the sum of the four angles is equal to 360 degrees.
Below is the implementation of the above approach:
C++
// C++ program to check if a given // quadrilateral is valid or not#include <bits/stdc++.h>using namespace std;// Function to check if a given // quadrilateral is valid or notbool Valid(int a, int b, int c, int d){ // Check condition if (a + b + c + d == 360) return true; return false;}// Driver codeint main(){ int a = 80, b = 70, c = 100, d = 110; if (Valid(a, b, c, d)) cout << "Valid quadrilateral"; else cout << "Invalid quadrilateral"; return 0;} |
Java
// Java program to check if a given // quadrilateral is valid or not class GFG{ // Function to check if a given // quadrilateral is valid or not public static int Valid(int a, int b, int c, int d) { // Check condition if (a + b + c + d == 360) return 1; return 0; } // Driver code public static void main (String[] args) { int a = 80, b = 70, c = 100, d = 110; if (Valid(a, b, c, d) == 1) System.out.println("Valid quadrilateral"); else System.out.println("Invalid quadrilateral"); } }// This code is contributed// by apurva_sharma244 |

Output
Valid quadrilateral
