Type of triangle

TO FIND TYPE OF TRIANGLE :

#include<stdio.h>
#include<conio.h>
void main()
{
    int a,b,c;
    printf("enter 3 sides of triangle\n a\n b\n c\n = ");
    scanf("%d%d%d",&a,&b,&c);
    if(a==b&&b==c&&c==a)
        printf("equilateral triangle ");
    if(a==b||b==c||c==a)
        printf("isosceles triangle");
    else
        printf("scalene triangle\n");
    if(c*c==(b*b+a*a))
        printf("right angle triangle ");
    getch();
}

OUTPUT  :{ enter sides serial wise}
