This task is to find the number of 'For' loops present in the given cpp program.
--------
Question: int sum=0;//???????????
void fact(int a,int i)//?????;??????????a?????i?????
{
    if(a==1) sum++;//???????N=1????????N????????1
    while(i<=a)//????i???N
    {
        if(a%i==0) fact(a/i,i);//??N??i?????????????N/i??
        i++;//??N???i???i?1
    }
}
int main()//???
{
    int n;//?????????
    cin>>n;//??????
    while(n--)//??
    {
        int a;//??????????
        cin>>a;//????
        int i=2;//???????2?
		int result=1;//????????a??????
        while(i<=a/2)//??i???a???
        {
            if(a%i==0)//??i?a???
            {
                sum=0;//sum??
                fact(a/i,i);//????????/i
                result+=sum;//????????i????
            }
            i++;//i?1
        }
        cout<<result<<endl;//??????
    }
    return 0;

Question: int f(int a,int min)
{ 
	if(a<min)
	{ 
		return 0; 
	} 
	int result=1,i; 
	for(i=min;i<a;i++)
	{ 
		if(a%i==0)
		{ 
			result+=f(a/i,i);

Question: void factor(int x,int limit);
int result;
int main()
{
	int n;
	scanf("%d",&n);
	int input;
	for(int i=0;i<=n-1;i++)
	{
		scanf("%d",&input);
		result=1;//limit?2?????result=1;
		factor(input,2);//limit?2?????result=1;
		printf("%d\n",result);
	}
	return 0;
}
void factor(int x,int limit)
{
	int remainder;
	if(x<limit)
	{
		return;
	}
	for(int i=limit;i<=x;i++)
	{
		remainder=x%i;
		if(remainder==0)
		{
			if(x/i>=i)
			{
				result++;
				factor(x/i,i);
			}
		}
	}
}
