Im trying to create an object array that accepts values generated by a 2 random functions so that i can sort the objects in the array based on one value of an identifier (finishtime) in each object.
eg. twenty Activitys with datamembers [starttime, finishtime, id]
my code for the main.cpp file looks like this
#include "Activity.h"
//#define SIZE 20 //This is a GLOBAL SYMBOLIC CONSTANT
void swap(int X[], int i, int j);
void printData(int[], int);
void printSortedData(int[], int, int);
void bubbleSort(int A[], int size);
int randomStart(int x);
int randomFinish(int y);
int main()
{
srand(time(0));
int z;
int w;
int start[20];
int finish[20];
for (int i=1;i<21;i++)
{
start[i] = randomStart(z);
finish[i] = randomFinish(w);
Activity Acts[i](start[i],finish[i],i);
Acts[i].display();
}
int ActivityArray[20]={};
//cout<<"\n Sorting with Bubble Sort:\n";
//bubbleSort(Data, SIZE);
return 0;
}
int randomStart(int x)
{
x=0+rand()%69;
return x;
}
int randomFinish(int y)
{
y = 1 + rand()%(70-1)+1;
return y;
}
and i recieve the following errors
1>.\activity-main.cpp(30) : error C2057: expected constant expression [LINE 30]
1>.\activity-main.cpp(30) : error C2466: cannot allocate an array of constant size 0 [LINE30
1>.\activity-main.cpp(30) : error C2075: 'Acts' : array initialization needs curly braces [LINE 30]
