Reversing a string

[Jon15]

I am having trouble reversing the string so that I can input the name in the middle of the reversed string. Where is my function wrong?

  #include<iostream>
#include<iomanip>
#include<cmath>
#include<string>
#include<fstream>

using namespace std;


	string random;
	
	void reverse();
int main()
{
	
	string name;
	cout<<"Please input your name and a random string of characters"<<endl;
	cout<<"hit enter after your name"<<endl;
	getline(cin, name);
	getline(cin, random);

	reverse();

	random.insert(int(random.length())/2, name);
	
	cout<<random;

	system("pause");
	return 0;
}
void reverse()
{
	int i;
	int j = (random.length()-1);
	for(i = j; i>=0; i--)
	{
		random[i-j] = random[j];
	}

	return;
}

Can you tell me what the values for i and j (i-j would be helpful for you as well) are for each iteration of the loop on line 35? This will help you understand why it isn't working.
