Answer:
The expression for this question can be given as:
Expression:
ip + (ip + 1) + (*ip + 2)
Explanation:
In the question, it is given that the ip variable that is a pointer type variable has been declared and initialized. This variable result has been declared to be an array of 100 elements and it is also defined that the ip variable is an element of the first half of the array. So the expression of the sum of the elements that point the ip that is ip + (ip + 1) + (*ip + 2). In this expression, ip is a pointer variable that's value is increased by 1 and 2. and all the value will be added in the ip.
Explanation:
In a 512 byte memory unit, in order to address each byte, there will be 512 locations (each one byte) ranging from 0 to 511.
Thus it will take 9 bits (2^9=512) to store the address within the unit.
Answer:
Select commands would return all the rows and columns in the table.
Explanation:
In the database management system, it consists of one or more table. To handle this table it provides the concept of SQL(Structured Query Language). It is a programming language that design, manage, store data into the relational database. It is case sensitive language. In the SQL many commands used for handle table data, it returns all rows and columns from the table.
Syntax of select command can be given as:
Select * from tablename;
Example:
select * from ProductCategory;
returns all the data from the table.
In select command, we will also return select data by using condition
SELECT column1 [, column2, ...]
FROM tablename
WHERE condition
In the conditional clause we use these operators that can be given as:
= Equal, > Greater than, < Less than, >= Greater than equal to, <= Less than equal to, != Not equal to.
