check the triangle is valid or not using c++

 Question : if three sides of a triangle are entered through the keyboard, write a program to check whether the triangle is valid or not. the triangle is valid if the sum of two sides is greater than the largest of three sides.

source code 

#include <iostream>

#include<conio.h>

int greternum(int ,int,int); 

int sumofsmaller(int ,int ,int,int );

using namespace std;

int main()

{

int a,b,c,grater,smaller;

cout<<"Enter 3 number : ";

cin>>a>>b>>c;

grater=greternum(a,b,c);

smaller=sumofsmaller(a,b,c,grater);

//cout<<grater <<endl<<smaller <<endl;

if (smaller > grater)

{

cout<<"it is valid triangle ";

}

else 

{

cout<<"it is not valid triangle ";

}  

getch();

return 0;

}

int sumofsmaller(int a, int b,int c,int grater)

{

if (a<grater && b<grater)

{

return a+b;

}

else if (a<grater && c<grater )

{

return a+c;

}

else

{

return c+b;

}

}

int greternum(int num1,int num2,int num3)

{

if (num1<num2 && num3<num2)

{

return num2;

}

else if (num1<num3 && num2<num3 )

{

return num3;

}

else

{

return num1;

}

}
