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
    int bit_count = 0;
    int temp_data = data & 0x7F;
    int p_enable = ctrl->parity_enable;
    int p_type = ctrl->parity_type;
    while(temp_data)
    {
        if(temp_data&1)
        {
            bit_count++;
        }
        temp_data>>=1;
    }
    if(p_enable)
    {
        if(p_type)//odd parity
        {

            {

    return data;
}

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;

    uint8_t frame = create_uart_frame(data, &ctrl);
