Q:- Write a C program to Check Whether the Triangle is Equilateral, Isosceles and

        Scalene Triangle Using If Else ?

       Input

         #include<stdio.h>

         #include<conio.h>

         int main()

   {

int s1,s2,s3;

clrscr();

printf(“Enter Three Sides of Triangle =”);

scanf(“%d%d%d”,&s1,&s2,&s3);

if(s1==s2 && s2==s3)

{

printf(“Equilateral Triangle.”);

}

else if(s1==s2 || s1==s3)

{

printf(“Isosceles Triangle.”);

}

else

{

printf(“Scalene Triangle.”);

}

getch();

   }
