[PIC] how can I access CHAR type dtavariable bitwise in mplab in c language

#include<htc.h>
unsigned char temp;      //I want to access the each of bit of this 'temp' variable
                                    //HOW CAN I ASSIGN ALL THE BITS OF 'TEMP' SAPERATELY                   
                                        TO SOME BIT TYPE VARIABLE?

unsigned char top;
sbit a1 top^0;
sbit a2 top^1;
sbit a3 top^2;
sbit a4 top^3;
sbit a5 top^4;
sbit a6 top^5;
sbit a7 top^6;
sbit a8 top^7;

if( (temp >> 5) % 2)
   //bit 5 is SET

if (temp & (1<<5))
      //bit 5 is set

RA0 = (temp & 0x10) ? 1 : 0;
//set RA0 in the same value with the 5th bit of temp
    //

union {
  unsigned char val;
  struct {
         unsigned char b0:1;
         unsigned char b1:1;
         unsigned char b2:1;
         unsigned char b3:1;
         unsigned char b4:1;
         unsigned char b5:1;
         unsigned char b6:1;
         unsigned char b7:1;
  } bits;
} temp;

void main(){
      temp.val = 47;
      if(temp.bits.b5)
            //do something
}
