Which instruction set?

Also, count 1st n numbers? Isn't the answer n?

I think the OP meant count 1's in numbers.

lol... the count is itself "n"...what to count then ...WTF ...either there's something missing or question is disgustingly dumb!

In question , they asked that give the number of 1's in given number.

for example : number = 10 the 00001010 so number of 1's = 2

I will write C code we can convert later on

int numberofone = 0;

If ( number > 0 )
numberofone = 1;

while ( number > 0 )
{
if ( number & (number - 1 ) )
numberofone++;
number = number >> 1;
}

return numberofone;

int fun(int i)
{
int j=0,count=0;

while(i!=0)
{
j = i & 1;

if(j%2 != 0)
count++;
i = i>>1;
}

return count;
}

int main()
{
int i=0,j=0;

printf("\n Enter Number \n");
scanf("%d",&i);
j = fun(i);
printf("\n Number of 1's are %d\n",j);
return 0;
}

ALP to find some of first n numbers :

LDA N
MOV C,A
LDA 0
MOV B,A
MOV A,C

L1:
JZ EXIT
MOV C,A
L2:
INR B
DJNZ L2
MOV A,C
DJNZ L1

EXIT:
MOV A,B
