Thread: "class" problem

Hi everyone,
here is my question
I wrote a class as follows
I want to output the numbers if sh(n)==2or3or5or7
the problem is that error appears
C2440 cannot convert from 'int' to 'sh'

I know that the sh() in class sh cannot return numbers
but I don't know how to fix this problem.

thanks for helping.

Code:

class sh:public Item{
	int n;
public:
	int out();
	int th(int x){ 	
		int sum=0;
		for(int i=10;n>0;){
		sum+=x%10;
		x=x/10;
		} return x;
	}
	sh(Item *src,int x):Item(src){           
		while(x>10){
		x=th(x);
		} 
	}
};
int sh::out() {
	int n=source->out();
	source=new Filter(source,n);
	if(sh(n)==2||3||5||7) return n; 
}
