Program: calculate weight on Mars #include <iostream> using namespace std; red = scaffolding int main( ){ double marsmass = 6.4e-23; double marsrad = 3.4e6; pink = declarations double earthweight; double marsratio; cout << “What is your weight on earth?” << endl; cin >> earthweight; yellow = operators marsratio = 6.8e-12*marsmass/(marsrad*marsrad); cout << “Weight on mars is ” << marsratio*earthweight << endl; return 0; }

Functions and Procedures Functions and procedures encapsulate algorithms so they can be written once and used repeatedly, to avoid repetition in codes.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
