Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>
#include <stdint.h>
void Bit_Meaning(uint8_t bit)
{
    switch(bit){
    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");
            break;
    }
}
void decode_status(uint8_t status_reg) {
    // Your logic here
    for(int i=0; i<8; i++)
    {
        if(status_reg&(1<<i))
        {
           Bit_Meaning(i); 
        }
    }
}

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