Basic theorem of triangle

Now it is time to use C++ in our daily life.As a Mathematics student,you have read that the sum of two sides of a triangle is greater than the third side. 

So,today I am here with an interesting program that will input 3 numbers from the user and it will determine whether these sides form a triangle or not.

Below is the source code of this program.

Source code

#include<iostream>

#include<conio.h>

using namespace std;

int main()

{

int a,b,c;

cout<<"Enter the value of A:";

cin>>a;

cout<<"Enter the value of B:";

cin>>b;

cout<<"Enter the value of C:";

cin>>c;

if(a+b>c && a+c>b && b+c>a)

{

cout<<"The sides form a triangle."<<endl;

}

else

{

cout<<"The sides do not form a triangle."<<endl;

}

return 0;

}

Output

Explanation

As the user has entered A=10,B=20,C=30. So, 

A+B>C:10+20>30.

The condition becomes false in the start and it will go into the "else" condition and will display, "The sides do not form a triangle.
