|---|
| 54 | Q: What common programming language statement, in your opinion, is most
|
|---|
| 55 | detrimental to readability?
|
|---|
| 56 | A: "I believe the use of statements like goto and return in the middle
|
|---|
| 57 | of a program, which greatly reduce the reability"

|
|---|
| 59 | 10)
|
|---|
| 60 | Q: What are the arguments for writing efficients programs even though
|
|---|
| 61 | hardware is relatively inexpensive?
|
|---|
| 62 | A: * Hardware might be inexpensive, but not powerfull looking to
|
|---|
| 63 | embedded devices
|
|---|
| 64 | * A function might get called many times, making the overall program
|
|---|
| 65 | really slow
