This task is to find the number of 'For' loops present in the given cpp program.

int f(int,int);      //????
int main( )      //?????
{      //?????
	int n,i,a[50];
	cin >>n;      //??????
	for(i=0;i<n;i++){
		cin >>a[i];      //????
		cout <<f(a[i],2) <<endl;      //????
	}
	return 0;      //???????????????????
}      //?????
      
int f(int n,int p)      //????????????=p?????

{
	int sum=0,m;
	for(m=p;m<=n;m++)
		if(n%m==0){
			if(m<n) sum=sum+f(n/m,m);      //n?????m?????=n/i?????=m?????
			if(m==n) sum=sum+1;      //n?????n?????=1
		}
		return sum;      
}
