Does the variable i in the source code have to be of volatile type and static type in this application? (You may modify the source code and run it to verify/justify your answer

Here is the code:

int main(void) {

/* Init board hardware. */ BOARD_InitBootPins(); BOARD_InitBootClocks(); BOARD_InitBootPeripherals(); #ifndef BOARD_INIT_DEBUG_CONSOLE_PERIPHERAL /* Init FSL debug console. */ BOARD_InitDebugConsole(); #endif

PRINTF("Hello World ");

/* Force the counter to be placed into memory. */ volatile static int i = 0 ; /* Enter an infinite loop, just incrementing a counter. */ while(1) { i++ ; /* 'Dummy' NOP to allow source level single stepping of tight while() loop */ __asm volatile ("nop"); } return 0 ; }
