我都用上最笨的办法了，这个哪里有问题吗求助大佬

#include <iostream>
#include <cstring>
using namespace std;
int length(string x);
int main()
{
	string a,b,c;
	cin>>a>>b>>c;
	length(a);
	length(b);
	length(c);
	return 0;
}
int length(string x)
{
	int length=x.size();
	if(length==1)
	{
		cout<<"       "<<x<<" ";
	}
	if(length==2)
	{
		cout<<"      "<<x<<" ";
	}
	if(length==3)
	{
		cout<<"     "<<x<<" ";
	}
	if(length==4)
	{
		cout<<"    "<<x<<" ";
	}
	if(length==5)
	{
		cout<<"   "<<x<<" ";
	}
	if(length==6)
	{
		cout<<"  "<<x<<" ";
	}
	if(length==7)
	{
		cout<<" "<<x<<" ";
	}
	if(length==8)
	{
		cout<<x<<" ";
	}
	if(length==9)
	{
		cout<<x<<" ";
	}
	return 0;
}
