Exercises

Re-write the following C codes in assembly.

1. While loop

   int a = 125;
   int b = 0;
   while(a>0){
     b += a;
     a -=2;
   }

2. While loop with a condition

   int a = 125;
   int b = 0;
   while(a>0){
     b += a;
     if(a>10)
       a -= 2;
     else
       a--;
   }

3. For loop

   b=0;
   for(i=0;i<10;i++)
     b = b+ i*2;
   

4. Double for loop

   b=0;
   for(i=0;i<5;i++)
     for(j=0;j<5;j++)
       b = b+ j*2;

5. Do-while loop with a condition

   int a = 125;
   int b = 0;
   do{
     b += a;
     if(a>10)
        a -= 2;
     else
       a--;
   }while(a>0)

6. Collatz conjecture

   int a = 21;
   while(a != 1){
     if(a%2 == 1)
       a = 3*a+1;
     else
       a = a/2;
   }
