C Program to Check Triangle is Valid or Not

C program to check whether a triangle is valid or not

This code checks whether a triangle is valid or not with given side measurements.
/* Aim: To check whether given dimensions of triangle are correct or not */

#include<stdio.h>
int main()
{
	int a,b,c,d,e,f;
 
	printf("\n Enter dimensions of triangle:-");
	scanf("%d%d%d",&a,&b,&c);
 
	d=a+b;
	e=a+c;
	f=b+c;

	if ((d>c) && (f>a)) 
	{ 
		if (e>b)
		printf("\n The triangle is valid with %d %d %d as dimensions \n \n",a,b,c);
		else 
		printf("\n The triangle is invalid with %d %d %d as dimensions\n \n",a,b,c);
	}
	return 0;
}

Output:

 Enter dimensions of triangle:-4 8 9

 The triangle is valid with 4 8 9 as dimensions
