Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    if(status_reg & (1<<0))
        printf("Power On\n");
    if(status_reg & (1<<1))
        printf("Error\n");
    if(status_reg & (1<<2))
        printf("Tx Ready\n");
    if(status_reg & (1<<3))
        printf("Rx Ready\n");
    if(status_reg & (1<<4))
        printf("Overheat\n");
    if(status_reg & (1<<5))
        printf("Undervoltage\n");
    if(status_reg & (1<<6))
        printf("Timeout\n");
    if(status_reg & (1<<7))
        printf("Reserved\n");        

}

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

Solving Approach

All the conditions are mentioned following if it satisfies, the corresponding status of the bit is printed.
