Your grandma gave you $100 when you were born. On your 1st birthday, she gives you $105. Your 2nd birthday, she gives you $110. Every birthday, she gives you $5 more than your last. Write a program which simulates this using a for loop and an accumulator. Ask the user how old they're turning and calculate how much they will receive this year as well as the total amount of money they have ever received from grandma.
EXAMPLE: On your 5th birthday, you will receive $125. Over your whole life, you will have received $675.
Answer:
#include <stdio.h>
int main(){
int total_amount = 100;
int age, i, amount;
printf("How old are you?: ");
scanf("%d", &age);
//int amount = 100 + (age * )
for (i = 1; i <= age; i ++){
amount = 100 + 5 * i;
total_amount += amount;
}
printf("On your %dth birthday you will receive $%d\n\n", age, amount);
printf("Over your whole life you will have received $%d\n", total_amount);
return 0;
}
Explanation:
We start with initial value for total_amount = 100 since at age 0, the total_amount = 100
The Euclidean algorithm - The Euclidean algorithm provides a wonderful way to
calculate the greatest common factor of 2 numbers. The greatest common factor,
which is the largest number that divides evenly into 1 or more numbers, is useful
for reducing fractions. The Euclidean algorithm works by dividing 1 number by
the other and finding the remainder. The 2 numbers are redefined, and then the
process is repeated. The process ends when the remainder is equal to 0.
Following is the pseudo code for the algorithm. In c++ use 145 and 87 to test your
program. The program will find the largest common factor of the numbers (the
answer should be 29).
The largest common factor of the numbers GCF (145, 87) is 29 when remainder R = 0, the GCF is the divisor, b, in the equation. GCF = 29.
How to Find the GCF Using Euclid's Algorithm?Do the division a ÷ b = c with remainder R given two whole integers where an is bigger than b.
Replace a with b, then R, and repeat the division.
Step 2 should be repeated until R=0.
When R=0, the greatest common factor, GCF, is the divisor, b, in the final equation.
Because the greatest common factor (GCF) and greatest common divisor (GCD) are interchangeable, the Euclidean Algorithm approach may also be used to discover the GCD.
145 ÷ 87 = 1 R 58 (145 = 1 × 87 + 58)
87 ÷ 58 = 1 R 29 (87 = 1 × 58 + 29)
58 ÷ 29 = 2 R 0 (58 = 2 × 29 + 0)
When remainder R = 0, the GCF is the divisor, b, in the last equation. GCF = 29
Since the remainder is zero, the algorithm stops and therefore, the GCF (145, 87) is 29.

question 3. a full ternary tree is a tree whose internal nodes each have exactly three children. (a) write a recursive definition for a full ternary tree. (b) write a recursive definition for the number of internal nodes i(t) in a full ternary tree. (c) write a recursive definition for the number of external nodes e(t) in a full ternary tree. (d) write a recursive definition for the total number of nodes n(t) in a full ternary tree.
Each node in a ternary tree can have a maximum of three children, which are typically labeled "left," "mid," and "right."
A 3 height perfect binary tree contains 23+1 - 1 = 15 nodes. The tree must therefore be stored in 300 bytes. The tree will have 7 nodes if it is at least 3 feet tall and has the required number of nodes. Node 1 serves as the ternary tree's root node, and it has three children: Nodes 2, 3, and 4. Therefore, Node 3's parent node and the ternary tree's root node are the same. There are 2n+1 nodes in a full binary tree with n non-leaf nodes. Each non-leaf node in a binary tree provides two edges.

when you use a(n) language, you create programs by putting together a collection of objects. question 41 options: object-oriented collective object-based high-level
When you employ an object-oriented language, you build programs by assembling a group of objects.
In contrast to functions and logic, object-oriented programming (OOP) organizes software design around data or objects. Objects can be defined as data fields with specific traits and behaviors.
Instead of focusing on the logic required to handle the objects, OOP focuses on the objects that developers want to control. This approach of programming works best with large, complex, and frequently updated programs. This encompasses mobile applications as well as design and production software. Software to simulate manufacturing systems, for instance, can be developed using OOP.
Due to object-oriented software's organizational structure, the approach is excellent for collaborative development when projects are broken up into groups.

some computer systems do not provide a privileged mode of operation in hardware. yes it possible to construct a secure operating system for these computers
This is theoretically possible by carefully monitoring and scrutinizing the output of just one process while it is being performed. To ensure that we are aware of each process's priority, we must take into account the fact that this will undoubtedly reduce the system's efficiency (it will function considerably more slowly) (which is rather hard if we do not have modes).
This type of equipment would require an operating system that could only operate in control (or monitor) mode. There are two ways that this could be done:
a. Software emulation of all user programs (such as some BASIC, Java, and LISP systems, for instance). What the hardware lacks, the software interpreter would supply in software.
b. Require meant that all programs must be written in high-level languages in order for compilers to output all object code. The protection checks for the missing hardware would be generated by the compiler (either internally or through function calls). It would be an absurdly difficult code.

what allows the internet assigned numbers authority (iana) to segment any address space to define larger or smaller networks as needed, giving far more flexibility to allocate networks of virtually any size without wasting large blocks of ip addresses?
IP addresses for the Internet are distributed by the Internet Assigned Numbers Authority (IANA).
The IPv4 addresses with four groups of numbers, with which we are most familiar today, are no longer available, according to the IANA. There are five global regions (sometimes referred to as RIRs) inside IANA, and each one provides IP addresses for devices within that region. On February 3, 2011, IANA distributed the final blocks/groups of IPv4 addresses, one block of /8 addresses, to each region. With each area being exhausted, this practically means that IANA is currently out of addresses. The first to expire in 2011 was APINC (Asia Pacific area).and have since assigned actions to prolong them as much as feasible. After that, LACNIC (Latin America) expired in 2014. In 2015, the free address pool of ARIN (North America) was depleted. On November 25, 2019, RIPE (region of Europe) expired.
