Java: Loop Exercises 1

Name: _________________________________

What is the value of the variable n after the code in these questions? If a loop never finishes, put infinite in the answer space.

Assume: int i, j, n;

1. Value of n? __________

      n = 0;
      i = 1;
      while (i < 4) {
         n++;
         i++;
      }
   

2. Value of n? __________

      n = 0;
      i = 1;
      do {
         n++;
         i++;
      } while (i <= 5);
   

3. Value of n? __________

      n = 0;
      i = 1;
      while (!(i > 4)) {
         n = n + 1;
      }
   

4. Value of n? __________

      n = 0;
      i = 1;
      while (i < 4) {
         for (j=1; j<=i; j++) {
            n += 1;
         }
         i = i + 1;
      }
   

5. Value of n? __________

      n = 0;
      i = 3;
      while (i < 4) {
         n++;
         i--;
      }
