modify the code you developed for problem 1 in hw_05 so that the function x_to_the_n() is called by reference. hint: declare the function arguments as pointers.
This program calculates the power of an integer to an integer #include long int x_to_the_n(int x, int n) int i; long int a = 1; n; ++i) for (i = 1; i <= a = a*x; return a; int main(void) E int x, n; long int b; printf ("Enter an integer x and power n:\n"); scanf("%i $i", ex, en); b = x_to_the_n(x, n) ; printf("$^$i = $11.",x,n,b); return 0;

Answers

Answer 1

To modify the code in problem 1 from hw_05 to use call by reference, you need to change the function signature and function definition of x_to_the_n() to accept pointers as arguments.

How can the code in problem 1 from hw_05 be modified to use call by reference?

The modified code for problem 1 in hw_05 makes use of call by reference by declaring the function arguments as pointers.

This allows the function x_to_the_n() to directly modify the values of x and n in the main function. The program prompts the user to enter an integer x and power n, and then calculates the result using a loop.

The updated value of a is returned from the function and assigned to the variable b. Finally, the calculated result is printed using printf.

By using call by reference, any changes made to x and n within the function x_to_the_n() will reflect in the main function as well.

The null hypothesis tested in a one-factor analysis of variance can be expressed as follows: O Group = 0 Restate this hypothesis in terms of the means of the groups that are being compared Edit View Insert Format Tools Table 12pt Paragraph B TUA2 O words naattaan

Answers

The null hypothesis tested in a one-factor analysis of variance can be expressed as follows: The means of the groups being compared are equal.

How to explain the null

In a one-factor analysis of variance (ANOVA), the null hypothesis states that there is no significant difference in the means of the groups being compared. It assumes that all the groups have the same population mean. The alternative hypothesis, on the other hand, suggests that there is a significant difference in at least one of the group means.

By stating the null hypothesis as "The means of the groups being compared are equal," we are essentially testing whether the observed differences in the sample means are merely due to random variation or if they represent true differences in the population means.

fill in the blank : the ripple blanking feature often included in a _______ allows for suppression of leading or trailing zeros in a multiple digit display, while allowing zeros to be displayed in the middle of a number.

Answers

The ripple blanking feature often included in a digital counter allows for the suppression of leading or trailing zeros in a multiple-digit display while allowing zeros to be displayed in the middle of a number.

The ripple blanking feature is commonly found in digital counters, such as ripple counters or shift registers, which are used to drive multiple-digit displays. It provides a mechanism to control the display of zeros in a multi-digit number. The purpose of ripple blanking is to enhance readability by suppressing unnecessary leading or trailing zeros while still allowing zeros to be displayed in the middle of a number.

When the ripple blanking feature is enabled, leading or trailing zeros in a number are not displayed, resulting in a more concise representation of the number. However, zeros that appear in the middle of the number, between non-zero digits, are still shown. This helps avoid ambiguity in the display while reducing visual clutter. By utilizing the ripple blanking feature, digital counters can optimize the presentation of numerical information on multi-digit displays, making it easier for users to interpret the displayed values. This feature is particularly useful in applications where leading or trailing zeros are not significant and can be safely omitted without affecting the overall understanding of the displayed numbers.

encryption is the process of a. placing information in the de-militarized zone b. adding a password to information c. placing information behind a firewall d. rendering information unreadable in such a way that authorized users may later make the information readable

Answers

Encryption is a process of converting plain text or information into an unreadable format that is difficult for unauthorized users to access. It involves the use of mathematical algorithms and complex codes to scramble the data, making it impossible to read without the proper decryption key.

The main goal of encryption is to protect sensitive information from unauthorized access and ensure the confidentiality and integrity of data.When encrypting data, the information is typically placed in a secure location, such as a secure server or a cloud-based storage platform that has built-in security features.

This location is often referred to as a de-militarized zone (DMZ), which is a network segment that sits between the public internet and a private network. The DMZ acts as a buffer zone, preventing direct access to the internal network while still allowing authorized users to access specific resources.In addition to placing information in a secure location, encryption often involves adding a password or passphrase to further protect the data.

This helps to ensure that only authorized users with the correct credentials can access the information. Encryption also involves using complex algorithms and codes to scramble the data, making it unreadable to anyone without the proper decryption key.Encryption is particularly important for businesses that deal with sensitive information, such as financial data, medical records, and customer information.

the element that automatically assigns an ip address to a newly-appearing lan host is:

Answers

The element that automatically assigns an IP address to a newly-appearing LAN (Local Area Network) host is called a Dynamic Host Configuration Protocol (DHCP) server.

DHCP is a network protocol commonly used in LAN environments to automate the process of IP address assignment. When a device joins a LAN, it sends a DHCP request, and the DHCP server responds by assigning an available IP address from a pool of addresses. This automatic assignment saves network administrators from manually configuring IP addresses for each device on the network.

The DHCP server not only assigns IP addresses but also provides additional configuration information such as subnet masks, default gateways, DNS (Domain Name System) servers, and other network parameters. This allows the newly connected host to quickly and seamlessly integrate into the network without requiring manual network configuration.

DHCP servers are typically present in routers, switches, or dedicated DHCP server devices within the LAN infrastructure. They play a crucial role in managing IP address allocation and ensuring efficient network connectivity for devices joining the LAN.

True/False: a cardinality constraint tells what kinds of properties are associated with an entity.

Answers

False. Cardinality constraint is a type of constraint used in data modeling that specifies the maximum number of occurrences of an entity that can be associated with another entity. It does not determine what kinds of properties are associated with an entity.

A cardinality constraint is used to define the relationship between two entities in a database. It specifies the number of instances of an entity that can be related to another entity. For example, a one-to-many cardinality constraint states that an instance of one entity can be associated with multiple instances of another entity, but an instance of the other entity can only be associated with one instance of the first entity. On the other hand, the attributes of an entity define the properties that are associated with the entity. Attributes describe the characteristics of the entity, such as its name, size, or color. In data modeling, it is important to distinguish between cardinality constraints and attributes to properly define the relationships between entities in a database.
