When I try to compile with make file, I get the following error

/usr/local/include/cs50.h:177:91: note: expanded from macro 'get_float'
#define get_float(...) __extension__ IF_ELSE(ISEMPTY(__VA_ARGS__))(WARN(get_float(NULL)))(get_float(__VA_ARGS__))

Answer 1

This is because you forgot to include the code inside of a main function.

int main()
{
  // your code here,
}
