Thread: binary value

i am a neb and i really need help on this whe i type in charater A the program gives me 66, which is wrong it should be 65.

Code:

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>

void getBinary(char ch);
/*int getBit(char ch,int x) ;
void changeBit(char ch, int x);
*/
int main(int argc, char* argv[])

{
	char a;

	printf("Enter a character");
	scanf("%c",&a);
	getBinary(a);
	//printf("the new character after the bit change is %i",ch);
	getch();

	return 0;
}

 void getBinary(char ch)
 {
	int mask = 128;
	int i;
	printf("\nThe binary value of %c is:");
	for (i=0; i <=8; i++)
	{
		if ((ch &mask)!=0)
			printf("1");
		else
			printf("0");
		ch=ch<<1;
	}

 }
/* int getBit(char ch,int x)
 {

 }
 void changeBit(char ch, int x)
 {

 }
 */

Did you notice that you printed nine bits?
