Given a string, an integer position, and a character, all on separate lines, find the character of the string in that position and
replace it with the character read. Then, output the result.
Ex: If the input is:
warn
0
e
the output is:
earn
Note: Using a pre-defined string function, the solution can be just one line of code.
I am looking for the code for C++ NOT Python. Thanks
Answer:
Assuming the input string variable is named `input`, the input int variable is named `index`, and the input char variable is named `ch`:
```
input[index] = ch;
cout << input;
```
Explanation:
In C++, you can change specific elements of a string without having to overwrite the entire string (i.e. in C++, strings are mutable).

____is the amount of time it takes the processor to eead memory
A.Access time
B. Clock time
C. cycle time
D. Cycle per second
Answer:
B. Clock time
Explanation:
please mark me brainliest pleaseThe time it takes the CPU to read data from memory is referred to as access time. Then the correct option is A.
What is the Access time?When a request is made, the memory usage time measures how long it takes to get the first information character. It takes into account the time it takes to spin the disk to the section and move the read/write head to the record (seek time) (latency).
The amount of time it takes to move a symbol from or to the CPU from RAM is known as the data transfer delay. Access times for quick Memory modules are 10 nanoseconds (ns) or less.
The time taken by the processor to carry out the particular set of data or information from the memory to the processor (CPU) is known as access time.
Access time is the amount of time it takes the processor to read memory. Then the correct option is A.

Answer and explanation:
1. It asks for the total expenses for the month of March. So, let's add all of the March expenses up.
1,600 + 2,100 + 850 + 480 + 2,800 = $7,830 (which is the answer)
2. It asks what the highest expense for wages are. That would be $5,080. Out of all of the times that the wages have been paid, in April, it was the highest, at $5,080. So, $5,080 is the answer.
3. It asks how many items cost less than $1,000 in April. The only thing that cost less than $1,000 in April was the water because it only cost $370. So, the answer would be 1.

B) The set of instructions that your computer executes
C) The physical devices that make up a computer system
D) The physical devices and the set of instructions that your computer executes
Answer:
Computer hardware includes the physical parts of a computer, such as the case,[1] central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.[2]
Explanation:
By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is "hard" or rigid with respect to changes, whereas software is "soft" because it is easy to change.
Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware.

Time complexity gives a rough idea of how long it will take for an algorithm to execute
based on two things: the size of the input it has and the amount of steps it takes to complete,
whereas space complexity is also the amount of memory required to execute an algorithm based
on the size of input it has or given.
Using mathematical notations or diagrams critically explain the time and space complexity of the
code below. 10 marks
int a = 0;
for (i = 0; i < N; i++) {
for (j = N; j > i; j--) {
a = a + i + j;
}
}
Answer:
Explanation:
O(N*N) or O(N2).
Explanation:
The time complexity can be measured by caculating the number of times the loop will execute.
The above code runs total no of times
= N + (N – 1) + (N – 2) + … 1 + 0
= N * (N + 1) / 2
= 1/2 * N^2 + 1/2 * N
O(N^2) times.
Thus Time complexity is O(N*N) or O(N2).
When i=0, it will run 0 times.
When i=1, it will run 1 times.
When i=2, it will run 2 times and so on.
So the time complexity will be O(N*N) or O(N2).
The function O(n2) has a complexity that is proportional to the square of the input size.
O(n2) with 2 total iterations.
O(N^2) is for → 2 nested “for loops”
We usually want to know how many steps an algorithm will take for an input of size ‘N' when calculating complexity.
This example contains two ‘for' loops, each of which will execute ‘N' times for each element ‘N'. As a result, it will run N2 times in total. In large O notation, we'd state the complexity of this algorithm is O(N2).
Time Complexity:
The amount of time it takes an algorithm to finish a computation.
What factors contribute to the complexity of time?
Looping (for, while)
Big O Notation:
The language and metric we use to describe how long an algorithm takes to run.
O(n²) Quadratic Time
Two nested loops are involved.
Each item from two different collections must be compared to one another.
Space Complexity:
Space complexity is the measurement of memory (space) that an algorithm requires, similar to time complexity.
What determines the complexity of space?
Variables
Allocations
Space Complexity: O(1) space
Because of the nested for loops The time complexity is going to be quadratic.
As a result, the Space Complexity will be O(1) space.
Worst case space complexity: O(1)
Hence,
Time Complexity: O(n²)
Space Complexity: O(1)
explain how you would use Personal Firewalls and a Network Firewall to secure your home network.
Explanation:
Since each firewall is different, you will need to read and understand the documentation that comes with it to determine whether the default firewall settings are sufficient for your needs. This is particularly concerning because the “default” configuration is typically less restrictive, which could make your firewall more susceptible to compromise. Alerts about current malicious activity (e.g., CISA’s Alerts) sometimes include information about restrictions you can implement through your firewall.
