Thread: operator has no effect ??

Hi
I do not understand why the compiler is returning the message
'|' has not effect; expected operator with side effect on the line

saved_char|0x080;

Code:

#include <stdio.h>


int main(int argc,char **argv)
{

	int input_char;
	int saved_char;
	int i,rotate,temp;
	int input_array[8];
	int rotate_array[8];


	printf("What is the input character?");
	scanf("%c",&input_char);

	saved_char=input_char;

	for(i=0;i<8;i++)
	{
		if((input_char&1)==1)
			input_array[i]=1;
		else
			input_array[i]=0;

		input_char>>=1;
	}

	printf("\n\nArray is\n");
	for(i=7;i>-1;i--)
		printf("%d",input_array[i]);

	printf("how many bits rotation");
	scanf("%d",&rotate);

	for(i=0;i<rotate;i++)
	{
		if((saved_char&1)==1)
			temp=1;
		else
			temp=0;

		saved_char>>=1;
		
		saved_char|0x080;
		
	}

	for(i=0;i<8;i++)
	{
		if((saved_char&1)==1)
			rotate_array[i]=1;
		else
			rotate_array[i]=0;

		saved_char>>=1;
	}
	printf("\nAfter rotation\n\n");

	for(i=7;i>-1;i--)
	{
		printf("%d",rotate_array[i]);
	}
	
	


	getch();


	return 0;
}

thanks dudes
