clrscr();
printf("\nEnter the sides of triangle : \n");
scanf("%lf%lf%lf", &a, &b, &c);

s = (a + b + c) / 2;
area = sqrt(s * (s - a) * (s - b) * (s - c));

Answer 1

From stackoverflow:
"conio.h is a c header file used in old MS-DOS compilers...

The #include <curses.h> will give you almost all the functionalities that was provided in conio.h"

conio.h seems to be very depricated. ;)

Answer 2

It works fine after removing conio.h file atleast on sololearn not sure about other platforms

Answer 3

Where you running this code..? What problem your getting? I executed it with output..

Here, conio.h is deprecated api, don't works here. .. Remove conio.h, getch(), clrscr()... (But it works on old compliers, not here)
Make int main()

Put a space in scanf between specifiers..
