If the three sides of a triangle are entered through the keyboard, write a program to check whether triangle is equilateral, isosceles or scalene triangle.
#include<stdio.h>
#include<conio.h>
void main()
{
int s1,s2,s3;
clrscr();
printf("Enter three sides of a traingle");
scanf("%d%d%d",&s1,&s2,&s3);
if(s1==s2 && s2==s3 && s1==s3)
{
printf("\n Equilateral triangle");
}
else if(s1==s2 || s2==s3 || s1==s3)
{
printf("\n Isosceles triangle");
}
else
{
printf("\n Scalene traingle");
}
getch();
}
Output1:
Enter three sides of a triangle: 25 25 25
Equilateral triangle
Output2:
Enter three sides of a triangle: 25 25 45
Isosceles triangle
Output3:
Enter three sides of a triangle: 25 35 56
Scalene triangle
