Programming

Can someone pls tell me how is the operation different in the following two code snippets?


main()
{
int temp=20742;

short temp1;
temp1 = temp << 8;
printf("The vaue is %d\n",temp1>>8);}

result:6

main()
{
int temp=20742;

short temp1;
temp1 =(temp << 8)>>8;
printf("The vaue is %d\n",temp1);}

result: 20742

If I want to do the operation that I have done in the first code snippet in a single line without using any temp variables, how do I do it?

Thanks,
Anitha

Code:

int main()
{
  int temp=20742;
  short temp1=temp & 0x00ff;
  printf("The value is %d\n",temp1);
  return 0;
}

you have used short datatype for temp1,
sizeof short datatype=2
sizeof int datatype=4

use as int temp1

Matrix -
IMO - the OP is trying to zero out the three high-order bytes in the temp variable.
You are right to keep datatypes matching and the OP should just "and" away unwanted stuff:

Code:

int temp=20742 & 0x000000ff;

that's fine Jim...

What's that IMO exactly ..?
