Basic blocks are identified because they are known to be a straight line that is known also as a code sequence that tends to have no branches in regards to its in and out branches and its exception is only to the entry and at the end.
Note that Basic Block is said to be a composition of statements that is known to be one that often always executes one after other, and this is often done in a sequence.
<h3>How do you create a flow graph from the basic blocks?</h3>
Flow graph is gotten by:
- Lets Block B1 be the initial node and also Block B2 will tend to follows B1, so from B2 to B1 there is seen a kind of an edge.
Note that the first task is for a person to partition a sequence of three-address code and this is done into basic blocks.
Hence, Basic blocks are identified because they are known to be a straight line that is known also as a code sequence that tends to have no branches in regards to its in and out branches and its exception is only to the entry and at the end.

Explanation:
Both Primary Key and Candidate Key are the attributes that are used to access tuples from a table. These (Primary key and Candidate key) are also can be used to create a relationship between two tables.
- A Candidate Key can be any column or a combination of columns that can qualify as a unique key in the database. Each Candidate Key can qualify as a Primary Key.
- A Primary Key is a column or a combination of columns that uniquely identify a record. The primary key is a minimal super key, so there is one and only one primary key in any relationship.
<em> The main difference between them is that a primary key is unique but there can be many candidate keys. </em>
