C programming

Answer the 2 questions and modify the code to make led00 blink then modify it to make led02 blink. (Note this is using a ZCU104 evalution board)

#include

#include

#define ONE_SEC 33000000

int main() {

XGpio output;

int led_val = 0, count;

XGpio_Initialize(&output, XPAR_AXI_GPIO_1_DEVICE_ID); // initialize output XGpio variable

XGpio_SetDataDirection(&output, 1, 0x0); // LED outputs, 0 = output 1 = input

while (true) {

XGpio_DiscreteWrite(&output, 1, led_val); // Write value to GPIO

led_val ^= 1; // 1. What do these two lines do?

led_val &= 1;

for (count = 0; count < ONE_SEC; count++); // 2. What does this line do?

}

}

The questions are in the program
