Answer:

The answer is "Option b".

Explanation:

In the given-code variable "userEntry" is defined that prompt the user to input value and in the next step, the conditional statement is used, which checks the input value is not a number and greater than 500 with use of OR operator. if the condition is true it uses the alert box to print the message, that's why in this question except "choice b" all were wrong.

<h3>What does the technical term "field" mean?</h3>

A field is a purpose-driven, typically fixed-sized section in a fixed or known location within a unit of data, such as a record, message header, or computer instruction. A field may be divided into smaller fields depending on the situation.

<h3>What does a file structure field mean?</h3>

A record is an entire set of fields, a field is a single piece of information, and a file is a collection of records. An analogy between a file and a phone book is a phone book. There is a list of records in it, and each record has three fields: a name, an address, and a phone number.

2. Write a simple program in C++ to investigate the safety of its enumeration types. Include at least 10 different operations on
erastovalidia [21]

Answer:

Check the explanation

Explanation:

To solve the question above, we will be doing some arithmetic and bit wise operations on enum values. in addition to that, we are asserting the array with INTCOUNT  and also printing the size of array i.e 12 and we are adding BIG_COUNT enum value to 5 and the result is 25.

#include<stdio.h>

enum EnumBits

{

ONE = 1,

TWO = 2,

FOUR = 4,

EIGHT = 8

};

enum Randoms

{

BIG_COUNT = 20,

INTCOUNT = 3

};

int main()

{

// Basic Mathimatical operations

printf("%d\n",(ONE + TWO)); //addition

printf("%d\n",(FOUR - TWO)); //subtraction

printf("%d\n",(TWO * EIGHT)); //multiplication

printf("%d\n",(EIGHT / TWO)); //division

// Some bitwise operations

printf("%d\n",(ONE | TWO)); //bitwise OR

printf("%d\n",(TWO & FOUR)); //bitwise AND

printf("%d\n",(TWO ^ EIGHT)); //bitwise XOR

printf("%d\n",(EIGHT << 1)); //left shift operator

printf("%d\n",(EIGHT >> 1)); //right shift operator

// Initialize an array based upon an enum value

int intArray[INTCOUNT]; // declaring array

// Have a value initialized be initialized to a static value plus

int someVal = 5 + BIG_COUNT; //adding constant and BIG_COUNT variable

printf("%d\n",someVal); //value will be 25

printf("%d",sizeof(intArray)); //value will be 12

return 0;

}
