This code is useful when you want to ignore unrecognized input.

// Remember this and the next function for error trapping
char input_menu(char m)
{
while(testforChar(m))
cin >> m;
return m;
}

bool testforChar(char t)
{
//Add additional if statements for more
if(t=='q' || t=='Q')
return false;
if(t=='m' || t=='M')
return false;
return true;
}
