What is indirection operator?
The indirection operator, typically represented by the asterisk (*) in languages like C and C++, is used to access the value at a specific memory address referenced by a pointer. When you dereference a pointer using the indirection operator, you retrieve or manipulate the data stored at that pointer's address. This operator is essential for working with dynamic memory and data structures like linked lists and trees.
What is indirection in c programming?
Example: *(int *)main = 5;

What does indisection mean?
Indisection is not a widely recognized term in English and may be a typographical error or a misinterpretation of "dissection" or "indirection." If you meant "dissection," it refers to the process of dissecting or analyzing something in detail, often used in biological studies or literature analysis. If you intended "indirection," it typically pertains to a method or approach that does not involve direct engagement or straightforward action. Please clarify if you meant something else!
Multiple indirection in c language?
C uses pointers for indirection. So, using a pointer to a pointer would be multiple indirection. For example, the following code uses multiple indirection:int i = 42;int *pi = &i;int **ppi = π**ppi++;printf("i is now %d\n", i);
What has the author Nitza Ben-Dov written?

What is the forces that cancel each other because they are equal in strength and oppotsie indirection?
The forces are vectors: the Tangent force vector and the Gradient vector force; mcdV/dr + Del PE = 0, where PE is the potential Energy
How many pointers can be used in a c program?
Answergenerally we use simple pointer, void pointer,null pointer, structure pointer. Answerzero or more (unlimited).
Explain reference variable and how it is different from pointer variable?
In JAVA, all variables are reference variables, and there are no pointer variables. Even though the platform may implement them as pointers, they are not available as such. In C, no variables are reference variables. They are a C++ enhancement. In C++ a reference variable is syntactically the same as a pointer variable, except that the use of the indirection operator (*) is implicit. You do declare reference variables slightly differently than pointer variables but, once you do so, they can be treated as non-pointer variables. Reference variables also cannot be redefined once they have been initialized to point to some object. They are const. Structurally, there is no difference between a pointer variable and a reference variable. They are both still pointers. The compiler just makes it easier to treat reference variables and non-pointer variables the same way.

What is ibatis frame work?
iBATIS is a Data Persistence Framework.iBATIS in other words is an additional layer of indirection between the classes and the tables allowing it in more flexibility in how classes and tables are mapped with out making any changes to the Data model and the Object model. The layer of indirection here is the SQL.This enables mapping SQL queries to POJOs-Plain Old Java Objects.This works like the same as JPA[Hibernate/Spring framework] but faster than that.The main advantages are-1. Reduces the amount of Java code to access a DataBase with the use of XML files containing SQL queries.2.Faster than JPA.3.Uses existing SQL Stored Procedures.
