Why is MonthlyBudget set_budget not displaying the numbers?

Okay, to be more specific, rather getting 500 to 75, I get 0's in fix.housing to fix.misc and don't know why.

MonthlyBudget fix;
MonthlyBudget set_budget;
// now you've created 2 structs of type MonthlyBudget. Both with all variables uninitialized
fix = set_budget; // This doesn't call your method set_budget()
// All you do is copy all those uninitialized variables from the struct named "set_budget" to your struct "fix".
// try something like this:

fix = set_budget.set_budget(); // This now calls the set-budget() method and returns 
// (yet another) struct of type MonthlyBudget

// To make it a bit nicer (not the best possible way but I don't wanna change your whole 
// "set_budget()" method now

// just write: 
MonthlyBudget fix;
fix = fix.set_budget();


This is still terrible code but it works as intended

Thanks. Really, the set_budget.set_budget was needed.
