Write a C program to check whether triangle is valid or not if angles are given.c

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char *argv[])

	if(sum == 180 && angle1 != 0 && angle2 != 0 && angle3 != 0)
	{
		printf("Triangle is valid.");
	}
	else
	{
		printf("Triangle is not valid.");

	return 0;
