Answer:
The correct option for the given question is option(B) i.e dot operator
Explanation:
Structure are collection of different datatypes member element .
Let us consider the example of structure
Struct test
{
int age ;
char name[45];
};
Here test is an "structure" which member is age of "integer" type and name of "String" type.if we have to access the member of structure,firstly we create structure variable name then after that we use dot operator which is also known as member access operator that access the members of structure.
struct test op;// structure variable name
op.age=12; // access the member age
For example
Following is the code in c language :
#include <stdio.h> // header file
struct test // structure declaration
{
int age ;
char name[45];
};
int main() // main function
{
struct test op;// structure variable name
op.age=12; // access the member age
printf("%d",op.age);
return 0;
}
Output:12
so correct answer is "dot operator"
Answer:
Unique
Explanation:
The correct word to fill in the gap is "unique". This is because the routines are not common or of any major standard but are special in their own ways
Answer:
In a class, a public data member are those member which can be accessible to all other classes in the computer program. By using public data member a class can modify its data member and its member function. Hence, the key member in class are not be declared as public.
It is declared as:
class public
{
public; // public access specifier
int a,b; // Data Member
}
In a class, a private data member are only access by member function inside the class as, it is completely invisible from the outside world. In this, member function and class variable are private by default.
class private
{
private; // private access specifier
int a,b; // Data Member
}
Answer: A. Validation rule
Explanation:
Validation rules can be used to ensure that fields are populated because they can verify if the data being inputted meet the requirements of the administrators by returning a 'True' or 'False' response after testing. If the result is false, the user will be unable to move on until they adjust the field.
For example, Field length checks on websites are a Validation rule where you are only allowed to input a set number of characters and anything less or more will be denied, such as in the case of inputting phone numbers.
By including a Validation Rule that the LeadSource field of the Lead record be populated when a Lead is converted, the developer will be able to make sure that a user populates the Lead Source field prior to converting a Lead.
