Surface Area Of A Sphere
The surface area of a sphere is equal to:
where r is the radius of the sphere.
Write an HLA Assembly language program that computes the surface area based on a radius. A sample program dialogue is shown below. However you decide to do it, your main program should include calling a procedure or function (atleast one...) to solve this problem.
Lemme calculate the surface area of a sphere!
Gimme r: 2.15
Surface Area = 58.0880
Lemme calculate the surface area of a sphere!
Gimme r: 3.9
Surface Area = 191.1345
Explanation / Answer
program surfaceArea; #include( "stdlib.hhf" ); static radius : real32; procedure computeSurfaceArea(r : real32); @nodisplay; @noframe; static returnAddress : dword; z : real32; begin computeSurfaceArea; pop(returnAddress); pop(r); push(returnAddress); finit(); fld( r ); fld( st0 ); fmul(); fldpi(); fld(4.0); . fmul(); fmul(); fstp( z ); stdout.putr32(z, 4, 10); ret(); end computeSurfaceArea; begin surfaceArea; stdout.put("Lemme calculate the surface area of a sphere!", nl); stdout.put("Gimme r: "); stdin.get(radius); stdout.put("Surface area is: ", nl); call computeSurfaceArea; end surfaceArea;
