Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>
#include <stdint.h>

void decode_status(uint8_t status_reg) {
    // Your logic here
for(int i =0; i<8;i++)
{
    if (status_reg & (1<<i))
    {
    switch(i)
    {
        case 0:
        printf("Power On\n");
        break;
        case 1:
        printf("Error\n");
        break;
        case 2:
        printf("Tx Ready\n");
        break;
        case 3:
        printf("Rx Ready\n");
        break;
        case 4:
        printf("Overheat\n");
        break;
        case 5:
        printf("Undervoltage\n");
        break;
        case 6:
        printf("Timeout\n");
        break;
        case 7:
        printf("Reserved\n");
        break;
    }
    }
}


}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    decode_status(reg);
    return 0;
}
