C Program to find area of Triangular Prism lateral surface

Program

#include<stdio.h>
void main()
{
	int a, b, c;
	int height;
	int area;
	printf("Enter side a:\t");
	scanf("%d", &a);
	printf("Enter side b:\t");
	scanf("%d", &b);
	printf("Enter side c:\t");
	scanf("%d", &c);
	printf("Enter the height:\t");
	scanf("%d", &height);
	area = (a + b + c) * height;
	printf("The lateral area of the triangular prism is:\t%d\n", area);
}

Output

Enter side a:	4
Enter side b:	4
Enter side c:	6
Enter the height:	3
The lateral area of the triangular prism is:	42
