why this code in c++ doesn't compile?

Question

i have a problem, clang tells me that i have to put brackets on the function's prototype:

#include <iostream>
#include <time.h>
#include <cstdlib>
using namespace std;

void Giocatore( int n_pedine; int base; int altezza; char *A ){
int x=n_pedine;
while(x>0){
A[srand()%base*altezza]='O';
x--;
}
}

int main(){
int altezza, base, x;
char A[altezza][base];
cin>>base>>altezza>>x;
for(int i=0; i<altezza; i++){
for(int j=0; j<base; j++){
A[i][j]='*';
}
}

char *pA=&A[0][0];

for(int i=0; i<altezza; i++){
for(int j=0; j<base; j++){
cout<<A[i][j];
}cout<<endl;
}//da eliminare a fine progetto

Giocatore (x, base, altezza, pA);
}

Answer 1

I didn't look in-depth, but the parameter list in the function definition should be comma-seperated, not semicolon-seperated. Furthermore you called srand() inside the function, where I think you meant rand().
Does that fix your issue?

Answer 2

And in main
Declare array A after taking inputs to base,altezza..
