Answer:
[1-9][0-9]{0,2}
Explanation:
The numbers to be matched consist of three digits with the following requirements:
- Digit 1 can take the values 1-9
- Digit 2 can take the values 0-9
- Digit 3 can take the values 0-9
- Digits 2 and 3 are optional, that is the number may consist of 1,2 or 3 digits in all.
Taking these into account, the overall regular expression can be represented as follows:
[1-9][0-9]{0,2}

Answer:
No for GOTO
Yes for Pointer
Explanation:
<u>GOTO statement</u>
This declaration is used to pass control to the program's marked declaration. The label is the valid identifier and is positioned just before the declaration from which the control is transmitted.
It becomes hard to trace a program's control flow, making it hard to comprehend the program logic. Any program in C language can be written without using a GOTO statement.
<u>Pointers</u>
A C # pointer is nothing but a variable holding another type of memory address. However, in C # pointer only the memory address of the value types and arrays can be declared.
C # supports pointers to a restricted extent. Unlike reference kinds, the default trash collection system does not track pointer kinds. Pointers are not allowed to point to a type of structure containing a type of reference or a type of reference.
During the garbage collection process, the C #garbage collector can move objects in memory as they wish. The C #offers a unique fixed keyword for telling Garbage Collector not to move an item. This implies that the place of the value kinds referred to is fixed in memory. This is called pinning in C #.
