Question

Help me fix this mess. I can only change code where specified. There is a problem near cat assignment maybe I can't put my finger on it.

#include <iostream> #include <string> #include <cassert> using namespace std; struct Cat { int lives; int age; string name; Cat(string new_name, int new_age){ name = new_name; lives = 9; age = new_age; } }; Cat fetch_and_kill_oldest(Cat** cat_array, int length){ //This function tries to find the oldest cat, take away one life, // and return it for petting or whatever. //Fix this function starting here Cat temp = cat_array[0]; for(int i = 1; i < length; i++){ if (cat_array[i].age > temp.age){ temp = cat_array[i]; } } temp.lives -= 1; return temp; //stop here } int main() { Cat fluffy("Fluffy", 1); Cat grumpy("Grumpy", 5); Cat crazy("Crazy", 3); Cat domino("Domino", 4); Cat* clowder[4] = {&fluffy, &grumpy, &crazy, &domino}; Cat output = fetch_and_kill_oldest(clowder, 4); assert(output.name == "Grumpy"); assert(output.lives == 8); assert(grumpy.lives == 8); //I'll replace Domino by an older cat and kill it twice. Cat goldie("Goldie", 9); clowder[3] = &goldie; output = fetch_and_kill_oldest(clowder, 4); output = fetch_and_kill_oldest(clowder, 4); assert(output.name == "Goldie"); assert(output.lives == 7); assert(goldie.lives == 7); cout << "All tests pass" << endl; }

Explanation / Answer

//This function tries to find the oldest cat, take away one life,
   // and return it for petting or whatever.
   //Fix this function starting herestruct

Cat *temp = (struct Cat*) malloc(sizeof(struct Cat));
   temp = cat_array[0];
   for(int i = 1; i < length; i++){
   if (cat_array[i]->age>temp->age){
   temp = cat_array[i];
   }
   }
   temp->lives -= 1;
   return temp;     //should point to something like temp->age or temp->name
   //stop here
   }
