如果给出角度，检查四边形是否有效

给定四个整数A 、 B 、 C和D ，它们以度数表示四边形的四个角。任务是检查给定的四边形是否有效。

例子：

Input: A = 80, B = 70, C = 100, D=110 
Output: Valid 

Input: A = 70, B = 80, C = 130, D=60 
Output: Invalid 
 

方法：
如果四个角之和等于 360 度，则四边形是有效的。

下面是上述方法的实现：

C++

// C++ program to check if a given
// quadrilateral is valid or not
#include 
using namespace std;
 
// Function to check if a given
// quadrilateral is valid or not
bool Valid(int a, int b, int c, int d)
{
    // Check condition
    if (a + b + c + d == 360)
        return true;
     
    return false;
}
 
// Driver code
int 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
// quadilateral is valid or not
class GFG
{
     
// Function to check if a given
// quadilateral 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 quadilateral");
    else
        System.out.println("Invalid quadilateral");
}
}

def Valid(a, b, c, d):
 
    # Check condition
    if (a + b + c + d == 360):
        return True;
     
    return False;
 
 
# Driver code
a = 80; b = 70; c = 100; d = 110;
 
if (Valid(a, b, c, d)):
    print("Valid quadilateral");
else:
    print("Invalid quadilateral");
