help me out, it says rand cant be used as a fuction when compiling.

```
#include <cstdlib>
#include <iostream>
#include <math.h>
#include <ctime>
using namespace std;
int main(int argc, char *argv[])
{
int i,rnumber,number,power,base,rand;
int randomise();//initialises random number generator
srand(time(0));
cout<<"ten random numbers from 0 to 99\n\n";
for(i=0;i<10;i++){
rnumber= rand()%100;
cout<<rnumber<<endl;
}
cout<<"\nusing built mathematics fuctions\n";
base=3;
power=4;
number=81;
cout<<base<<"to the power"<<power<<"is"<<pow(base,power)<<endl;
cout<<"the square root of"<<sqrt(number)<<endl;
number=6;
cout<<"the absolute value of"<<number<<"is"<<abs(number);
return 0;
system("PAUSE");
return EXIT_SUCCESS;
}
```
