Question 1

Consider the following function prototype: int seqSearch(const listType& list, int searchItem);
The actual parameter cannot be modified by ____.

Accepted Answer

The actual parameter 'list' is passed by const reference, which means its value cannot be modified inside the function. However, both the function name and searchItem are not actual parameters, but rather the function name is the function itself, and searchItem is passed by value, so they are not relevant to this question. The type 'listType' also does not play a role in whether the parameter can be modified or not.

Question 2

A struct variable can be passed as a parameter ____.

Accepted Answer

A struct variable can be passed as a parameter either by value or by reference depending on the specific requirements of the program. Passing by value makes a copy of the entire struct, which can be expensive in terms of memory usage and performance, whereas passing by reference allows for accessing and modifying the original struct directly without creating a copy. However, passing by reference can also introduce issues related to accidental modification of the original data, which can be avoided by passing by const reference. Therefore, the best choice depends on the specific needs of the program and the trade-offs between performance, memory usage, and data safety.

Question 3

Memory is allocated for struct variables only when you ____________________ them.

Accepted Answer

The answer of Memory is allocated for struct variables only...

Question 4

Consider the following statements. struct circleData
{
Double radius;
Double area;
Double circumference;
};
CircleData circle;
Which of the following statements is valid in C++?

Accepted Answer

The statement "cin >> circle.radius;" is valid in C++ as it correctly accesses the 'radius' member of the 'circle' object for input.

Question 5

Consider the following statements:  applianceType applianceList[25];
Which of the following best describes applianceList?

Accepted Answer

The syntax "applianceList[25]" indicates a one-dimensional array. However, since it is defined as "applianceType," which is likely a structure type (based on the naming convention), it is an array of structs. Therefore, C is the correct choice.

Question 6

If a variable is passed by ____________________, then when the formal parameter changes, the actual parameter also changes.

Accepted Answer

The answer of If a variable is passed by ____________________,...

Question 7

Question 10

You can assign the value of one struct variable to another struct variable of ____ type.

Accepted Answer

The value of one struct variable can only be assigned to another struct variable of the same type. This is because structs are user-defined data types and their variables have a specific set of member variables and data types. Assigning the value of one struct variable to another variable of a different type, such as a simple data or an array, would result in a type mismatch and a compilation error.

Question 11

Which of the following aggregate operations can be executed on array variables?

Accepted Answer

The answer of Which of the following aggregate operations can...

Question 12

Consider the following statements: struct rectangleData
{
Double length;
Double width;
Double area;
Double perimeter;
};
RectangleData bigRect;
RectangleData smallRect;
Which of the following statements is legal in C++?

Accepted Answer

Only D is legal as it compares the length of bigRect with the width of smallRect. The other options are not legal because A and B are trying to compare two struct variables directly without any custom comparison function, and C is trying to access a member of bigRect (length) that is not being compared with any member of smallRect.

Question 13

Consider the following statements:  applianceType applianceList[25];
Which of the following statements correctly initializes the cost of each appliance to 0?

Accepted Answer

Option A is incorrect because it is accessing a non-existent member within the applianceList array. Option B is incorrect because it is trying to set the 26th element of the array to 0, which is out of bounds. Option C is incorrect because the for loop should start at 0, not 1. Option D is correct because it correctly initializes each element in the array to 0.

Question 14

Consider the following struct definition:
const int ARRAY_SIZE = 1000;
struct listType
{
int listElem[ARRAY_SIZE];
int listLength;
};
The statement that declares intList to be a struct variable of type listType is ____________________.

Accepted Answer

The answer of Consider the following struct definition:
const int ARRAY_SIZE...

Question 18

Consider the following statements:  studentType1 student1, student2;
Struct studentType2
StudentType2 student3, student4;
Which of the following statements is valid in C++?

Accepted Answer

Question 19

Consider the following statements: struct rectangleData
{
Double length;
Double width;
Double area;
Double perimeter;
};

{
Double length;
Double...

Question 20

To compare struct variables, you compare them ____.

Accepted Answer

Struct variables consist of multiple members. To compare them, you need to compare their individual members, hence the correct choice is member-wise comparison.
