# 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--;
          }
