## __C++ Program to take the value from the user as input all sides of a triangle and check whether the triangle is valid or not. Using switch statement __

Given sides of the triangle , write a program to check whether it will form a valid triangle or not . For triangle to be valid the sum of two sides must be greater than third .

Note:- A triangle is valid if sum of its two sides is greater than the third side. If three sides are a, b and c, then three conditions should be met.

1.a + b > c

2.a + c > b

3.b + c > a

**Sample input **

1 10 12

**Sample output**

Invalid triangle

__C++ Program to take the value from the user as input all sides of a triangle and check whether the triangle is valid or not. Using switch statement __

The objective of the code is to check that sides of the triangle will form a valid triangle or not .

__Code(C++):-__

#include <iostream>

using namespace std;

int main() {

int a,b,c,s;

cout<<"Enter the sides ";

cin>>a>>b>>c;

s=a+b+c;

int ch=((a+b)>c && (b+c)>a && (c+a)>b);

switch(ch)

{

case 1:cout<<"Valid Triangle";

break;

case 0:cout<<"Invalid triangle";

break;

}

}

__Output:-__

Enter the sides

1 10 12

Invalid triangle
