Construct UART Data Frame with Parity Bit

Code

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

typedef struct {
    uint8_t parity_enable : 1;
    uint8_t parity_type   : 1;
    uint8_t reserved      : 6;
} UART_Control;

uint8_t create_uart_frame(uint8_t data, UART_Control *ctrl) {
    // Your logic here
    uint8_t temp = 0;
    if(ctrl -> parity_enable == 0){
       temp = temp << 7 ;
       temp = temp | data ;
       return temp;
    }
    else {
        temp = data;
        int count =0;
        for(int i=0;i<8;i++){
            if(temp &(1 << i)) count++;
        }
        uint8_t x = 0;
        if(ctrl -> parity_type == 0)
        {
            if(count % 2 ==0) x = (0 << 7);
            else  x = (1 << 7);
        }
        else{
           if(count % 2 ==0) x = (1 << 7);
            else  x = (0 << 7);  
        }
        return x | data;
    }
    return 0;
}

int main() {
    uint8_t data;
    scanf("%hhu", &data);  // 7-bit input

    uint8_t parity_enable, parity_type;
    scanf("%hhu %hhu", &parity_enable, &parity_type);

    UART_Control ctrl;
    ctrl.parity_enable = parity_enable;
    ctrl.parity_type = parity_type;

    uint8_t frame = create_uart_frame(data, &ctrl);
    printf("frame = 0x%02X", frame);

    return 0;
}
