I was recently studying C# where i came across following for loop
// Display the bits within a byte.
using System;
class ShowBits {
static void Main() {
int t;
byte val;
val = 123;
for(t=128; t > 0; t = t/2) {
if((val & t) != 0)
Console.Write("1 ");
if((val & t) == 0)
Console.Write("0 ");
}
}
}
I am not able to understand that Why in doing t=t/2 in the incrementing/decrementing section of the for loop . plz explain
It’s looping in decreasing powers of two and using that value in a mask.
(base 10): 128, 64, 32, 16, 8, 4, 2, 1
(base 2): 10000000, 01000000, 00100000, 00010000, 00001000, 00000100, 00000010, 00000001
