Why is my code working without declaring the square function in C and I'm directly using it?

It's likely compiler dependant. I think some versions​ of GCC will generate a warning, but still compile with our errors​. I think Sololearn will only output warnings​ if there are errors also.

it doesn't matter that you have written function at the bottom of main function or upper side you just need to write it to call in a program.

you have written your logic for the square of a number without using inbuilt libraries ..if u dont feel like developing ur own logic then you can use the in built pow function ...for example you can build your own logic for concatenating two strings or use the in built function called concat() which is available under string.h i suppose
