WebSep 30, 2024 · A straightforward solution is to load the variable to a register ( MOVZX EAX, [var1]) and then 16 times shift the lowest bit to CF ( SHR EAX,1) and add the CF to a counter register ( ADC ECX,0) each time. However, your code seems to count how many of four words in memory has a nonzero value. There are some bugs in it: WebThe number of iteration required is equal to the number of set bits in a given number. Here are the exact steps of this algorithm: 1. set the loop counter to zero to start with. 2. loop until number > 0. -- clear the least significant bit of number: number &= (number-1) -- increment the loop counter by 1: count++; 3. return the loop counter.
