    Code:
    int main()
    {
    	unsigned char a = 'a';
    	unsigned char c = 0;
    	unsigned char b[8];
    	char mask = 1;
    	int i;
    	
    	for(i = 8; i > 0; i--)
    	{
    		printf("%d", a & mask);
    		b[i - 1] = a & mask;
    		a >>= 1;
    	}
    
    	printf("\n");
    
    	for(i = 0; i < 8; i++)
    	{
    		c |= b[i];
    		c <<= 1;
    
    		if(b[i] == 1)
    		{
    			printf("1");
    		}
    		else
    		{
    			printf("0");
    		}		
    	}
    
    	printf("\n%c\n", c);
    
    	return 0;
    }
    most important part
    Code:
    c |= b[i]; //means c = c | b[i];
    c <<= 1;//means c = c << 1;
    nothing change still get the same old error result....

    Fascinating I'm sure, but what exactly do you expect to get? People sure don't know how to ask people to help them. Picture a conversation with someone:

    You: This doesn't work.
    Them: That's nice.
    You: Fix it.
    Them: What's wrong?
    You: This doesn't work.

    That's all well and good, but how about you actually tell us a bit more. How about we take a different turn in our conversation?

    You: This doesn't work.
    Them: That's nice.
    You: Fix it.
    Them: What's wrong?
    You: Well I input this, and I'm supposed to get this. But I don't, I get that instead.

    See how much better that is? Now you try.

    Since I'm such a nice guy, here's a hint:
    most important part
    Code:
    c |= b[i]; //means c = c | b[i];
    c <<= 1;//means c = c << 1;
