| =====Execution===== | =====Execution===== | ||
| + | Several operating behaviors are shown, namely, with and without command-line arguments and 1-, 2-, and 3-digit values. | ||
| + | |||
| + | First up, three digit value without argument: | ||
| <cli> | <cli> | ||
| Line 174: | Line 186: | ||
| Enter value: 345 | Enter value: 345 | ||
| 345 x 11 = 3795 | 345 x 11 = 3795 | ||

| + | |||
| + | Second, a two digit value without argument: | ||
| + | |||
| + | <cli> | ||
| + | lab46: | ||
| + | Enter value: 32 | ||
| + | 32 x 11 = 352 | ||
| + | lab46: | ||
| + | </ | ||
| + | |||
| + | Next, a one digit value with argument: | ||
| + | |||
| + | <cli> | ||
| + | lab46: | ||
| + | 7 x 11 = 77 | ||
| + | lab46: | ||
| + | </ | ||
| + | |||
| + | Finally, two digit value with argument: | ||
| + | |||
| + | <cli> | ||
| + | lab46: | ||
| + | 567 x 11 = 6237 | ||
