Can't get my do while loop to repeat

Here is a sample of my code, I'm trying to make a prompt for a user enter 1 for reset test, 2 to do something later, and 3 to exit. After pressing 1 the reset code executes, the code should then reask the user to input 1, 2 or 3; only after pressing 3 should the code exit. The reset code executes perfectly, but I can't get the prompt to repeat. My variable 'c' is declared as int, and 'quit' is declared as u8. I wanted to declare 'quit' as bool or boolean, but my compiler didn't recognize bool.



do
{
c=0;
TestFailed = 0;
TestSuccess = 0;
alt_printf("Enter 1 for reset test, 2 for ???, and 3 to exit");
c = alt_getchar();
alt_printf("You chose %s\n", c);

switch(c)
{
case '1':
alt_printf("Reset Test\n");
alt_printf("Entering reset loop with %x resets. \n", num_results);
for (ii = 0; ii < num_resets; ii++)
{
//Reset the core through reg read mod write to bit 4.
iprop_dev_portreset((u32*)DEV_BUS_SLAVE_BASE);
//poll on bit 5 of ADI_DEV_CORE_STATUS every 1 ms for when device is up and running timeout after 20ms
rc = iprop_wait_reg((u32*)(DEV_BUS_SLAVE_BASE + ADI_OFFSET + ADI_DEV_CORE_STATUS),
0x20, //only look at bit 5
0x00, //if bit-1 ==1, we're phy-ready
1, //wait 1us between register reads
100000); //~100ms
read = Iprop_RegRead32((u32*)DEV_BUS_SLAVE_BASE, ADI_OFFSET + ADI_DEV_CORE_STATUS);
if ((rc & 0x20) == DEV_STATUS_PHYRDY)
{
TestSuccess = TestSuccess + 1;
}
else
{
TestFailed = TestFailed + 1;
}
//sleep to allow the drive to send an initial d2h
percent_done = ii/(num_resets/10);
if (ii%(num_resets/10) == 0)
{
alt_printf("%x0%% Done\n", percent_done);
}
usleep(10);
}
alt_printf("Test Completed\n");
alt_printf("Successful Results: %x ", TestSucccess);
alt_printf("Failed Resets: %x ", TestFailed);
while(1)
{
}
return 0;
break;
case '2':
alt_printf("???");
while(1)
{
}
return 0;
break;
case '3':
alt_printf("Exiting");
quit = 0xFF;
while(1)
{
}
return 0;
break;
default:
alt_printf("Invalid entry %s", c);
while(1)

return 0;

}while (!quit);
