Here is the assignment:
Here's the assignment:
Implement a method countValue() that counts the number of times an item occurs in a linked list. Remember to use the STL list.
int countValue(list front, const int item);
Generate 20 random numbers in the range of 0 to 4, and insert each number in the linked list. Output the list by using a method which you would call writeLinkedList which you would add to the ListP.cpp.
In a loop, call the method countValue() , and display the number of occurrences of each value from 0 to 4 in the list.
Remember that all the above is to be included in the file ListP.ccp
Run: 2 3 4 0 1 0 2 4 2 3 3 4 3 3 3 0 0 2 0 2
0 : 5, 1 : 1, 2 : 5, 3 : 6, 4 : 3
and here is what I have so far:
#include<iostream>
#include<list>
#include<tchar.h>
int countValue(list<int> front, const int item);
using namespace std;
int _tmain(int argc, _TCHAR* argv[]){
list<int> front;
int listCount;
cout << "Enter the size of the list: ";
cin >> listCount;
for (int i = 1; i <= listCount; i++)
front.insert(rand()%5);
cout << "Original List of Values: " << endl;
//writeLinkedList(front, " ");
cout << endl;
for(int j=0;j<5;++j)
cout << countValue (front,j) << endl;
cout << endl;
return 0;
}
int countValue(list<int> front, const int item)
{ int count0;
int count1;
int count2;
int count3;
int count4;
list<int> *List;
for(list<int>::iterator i = front.begin(); i != front.end(); i++)
{
if(List->item == 0)
{
count0++;
}
if(List->item == 1)
{
count1++;
}
if(List->item == 2)
{
count2++;
}
if(List->item == 3)
{
count2++;
}if(List->item == 4)
{
count4++;
}
}
}
And here are the errors:
error C2065: 'list' : undeclared identifier line 5
error C2062: type 'int' unexpected line 5
error C2661: 'std::list<_Ty>::insert' : no overloaded function takes 1 arguments line 16

I just want to know what I've done wrong and how to fix it and also if someone could help me figure out if I'm doing the countValue function wrong or not based on the instructions I would really appreciate it. I've read the chapter in our textbook several times, looked up tutorials on youtube and on Dream in Code, and still I can not figure this out. All helpful information is appreciated!
