I made a class with private name, units sold, and units remaining.
I made two class methods that return, units sold and units remaining as ints.
I want to sort the units sold from greatest to least, but I get errors as I explain in the comments.
What am I doing wrong, is it something very obvious?
#include <iostream> #include <string> #include <fstream> using namespace std; const int MAX_SIZE = 1000; const char FILE_NAME[14] = "inventory.txt"; //make an Item class class Item { private: string name; int sold, remain; public: void set_name(string _name); void set_sold(int _sold); int get_sold(int); void set_remain(int _remain); int get_remain(int); void print(); }; //I erased all the methods setting name, sold, and remaining, they work though int Item::get_sold(int s) { s = sold; return s; } int Item::get_remain(int r) { r = remain; return r; } //greatest to least units sold void sort_sold(Item gL[], int ct) // ct is a global constant set to 1000 { //local variables int smallestPos; int temp; //for every position in the array for(int i=0;i<ct;i++) { //find the smallest element starting at that point smallestPos = i; for(int j=i+1;j<ct;j++) { if(gL[j].get_sold(j) < gL[smallestPos].get_sold(smallestPos)) { //found a smaller one, remember and keep going smallestPos = j; } } //see if we found something smaller than gL[i].get_sold(i) if(gL[i].get_sold(i) > gL[smallestPos].get_sold(smallestPos)) { //we did find a smaller one, so swap with gL[i].get_sold(i) temp = gL[i].get_sold(i); gL[i].get_sold(i) = gL[smallestPos].get_sold(smallestPos); //not assignable? gL[smallestPos].get_sold(smallestPos) = temp; //not assignable? } } }
