Chapter 10, Problem 10.9HW
Consider the following invocation of the fstatcheck program, from Problem 10.8:
linux> fstatcheck 3 < foo.txt
You might expect that this invocation of fstatcheck would fetch and display metadata for file foo.txt. However, when we run it on our system, it fails with a "bad file descriptor." Given this behavior, fill in the pseudocode that the·shell must·be executing between the fork and execve calls:
if (Fork() == 0) { /* child */
/* What code is the shell executing right here? */
Execve(“fstatcheck”, argv, envp);
}

In this challenge, the task is to debug the existing code to successfully execute all provided test files.
You are required to extend the existing code so that it handles std::invalid_argument exception properly. More specifically, you have to extend the implementation of process_input function. It takes integer as an argument and has to work as follows:
It calls function largest_proper_divisor(n).
If this call returns a value without raising an exception, it should print in a single line result=d where is the returned value.
Otherwise, if the call raises a std::invalid_argument exception, it has to print in a single line the string representation of the raised exception, i.e. its message.
Finally, no matter if the exception is raised or not, it should print in a single line returning control flow to caller after any other previously printed output.
To keep the code quality high, you are advised to have exactly one line printing returning control flow to caller in the body of…
Currently the function foo creates 4 partitions. How would increasing the number of partitions affect the runtime and space needed? Alternatively, how would decreasing the numbers of partitions affect these?Prove this by calculating the runtime and space for 10 and 1 partitions respectively.
Modify the program 11-10 from pages 753-755 as follows:
1. To Length class files (Length.h and Length.cpp) add the operator overload for stream insertion (<<) and stream extraction (>>) from page 759. You should not use the modified version of class Length from page 759 because it contains more operator overloads. Instead of typing you can use copy/paste from Length1.h and Length1.cpp respectively.
2. In main() replace the lines 11-16 with appropriate usage of stream extraction overload (>>) to change "first" and "second" objects with values inputted by the end user.
3. In main(), replace the output on lines 21,22 and 25,26 with appropriate usage of stream insertion (<<) operator.
The resulting output should be identical with the unmodified version of the program.
11-10:
// This program demonstrates the Length class's overloaded
// +, -, ==, and < operators.
#include <iostream>
#include "Length.h"
using namespace std;
int main()

(otherwise known as a slightly smiling faceLinks to an external site.) and any :( converted to ? (otherwise known as a slightly frowning faceLinks to an external site.). All other text should be returned unchanged. Then, in that same file, implement a function called main that prompts the user for input, calls convert on that input, and prints the result.
