Can anyone see...

why if the swimmers[x].name and temp match, why it would just go to ...
cout << " " << endl;
cout << " Press any key to return to menu ....";
input = getch();
if (input)
{
swim::displayMenu();
}

void Event::updateSwim()
{
char temp[50];
clrscr();
cout  <<  ""  << endl;
cout  <<  " Input Swimmers Name:  ";
cin.getline(temp,50);
cin.ignore();
int found = 0;
for (int  x = 0; x  < numSwimmers && found!=1; x++)
{
      if(strcmp(swimmers[x].name,temp) == 0)
       {
              found = 1;

....

It just goes on and on, how many swimmers do you have? Are you sure the name you input are exactly represented in your swimmers list ?
The code shown here is of no use what so ever. the proclaimed piece where you error out isn't even represented in the two segments, there isn't any part of it, which would be the smallest compilable part that shows your error....

What is the value of your currentE? What is the value of your inputv ? sometimes the easiest way to figure out why strange things happen, is to fill your code with debug output displaying every variable that might have some influence with the expected behaviour.
