Chapter 11, Problem 1RQE
Explanation of Solution
Primitive data type:
Primitive data types are pre-defined data types, which can be used directly by the programmers to declare the variables.
Some of the primitive data types available in C++
Integer:
- Integer is one of the predefined data types. The keyword used for declaring integer data type is “int”.
- It takes up to 4 bytes of memory space to store data. It ranges from -147483648 to 2147483647.
- Example for declaring integer data type is as follows:
- int variable1 = 10;
Floating point:
- Floating point is a predefined data type. The keyword used for declaring floating point is “float”.
- It takes up to 4 bytes of memory space to store data. It ranges from +/- 3.4e +/- 38.
- Example for declaring floating point data type is as follows:
- float variable1 = 10.3;
Character:
- Character is a predefined data type. The keyword used for declaring character data type is “char”.
- It takes 1 byte of memory space to store data. It ranges from -127 to 127 or 0 to 255
- Example for declaring character data type is as follows:
- char variable1 = 'a';
Boolean:
- Boolean is a predefined data type. The keyword used for declaring Boolean data type is “bool”. It stores data in the form of “true” or “false”.
- Example for declaring Boolean data type is as follows:
- bool variable1 = true;
Double Floating point:
- Double Floating point is a predefined data type. The keyword used for declaring double is “double”.
- It takes up to 8 bytes of memory space to store data. It ranges from +/- 1.7e +/- 308
- Example for declaring double data type is as follows:
- double variable1 = 11.34;
Void:
- Void represents null value. The keyword used for void is “void”.
Wide Character:
- Wide Character is a predefined data type. The keyword used for declaring wide character is “wchar_t”.
Example:
The below program demonstrates the usage of primitive data type “integer”:
//Include the header files
#include<iostream>
using namespace std;
//Main function
int main()
{
//Variable declaration
int i, n = 5;
//for loop to print 1 to 5
for (i = 1; i <= n; i++)
{
//print the value of “i”
cout << i << "\n";
}
//Print a new line
cout << "\n";
//Return the value 0
return 0;
}

UNIX Shell and History Feature [20 points] This question consists of designing a C program to serve as a shell interface that accepts user commands and then executes each command in a separate process. A shell interface gives the user a prompt, after which the next command is entered. The example below illustrates the prompt osh> and the user's next command: cat prog.c. The UNIX/Linux cat command displays the contents of the file prog.c on the terminal using the UNIX/Linux cat command and your program needs to do the same. osh> cat prog.c The above can be achieved by running your shell interface as a parent process. Every time a command is entered, you create a child process by using fork(), which then executes the user's command using one of the system calls in the exec() family (as described in Chapter 3). A C program that provides the general operations of a command-line shell can be seen below. #include #include #define MAX LINE 80 /* The maximum length command */ { int…arrow_forward
- Question#2: Design and implement a Java program using Abstract Factory and Singleton design patterns. The program displays date and time in one of the following two formats: Format 1: Date: MM/DD/YYYY Time: HH:MM:SS Format 2: Date: DD-MM-YYYY Time: SS,MM,HH The following is how the program works. In the beginning, the program asks the user what display format that she wants. Then the program continuously asks the user to give one of the following commands, and performs the corresponding task. Note that the program gets the current date and time from the system clock (use the appropriate Java date and time operations for this). 'd' display current date 't': display current time 'q': quit the program. • In the program, there should be 2 product hierarchies: "DateObject” and “TimeObject”. Each hierarchy should have format and format2 described above. • Implement the factories as singletons. • Run your code and attach screenshots of the results. • Draw a UML class diagram for the program.arrow_forward#include <linux/module.h> #include <linux/kernel.h> // part 2 #include <linux/sched.h> // part 2 extra #include <linux/hash.h> #include <linux/gcd.h> #include <asm/param.h> #include <linux/jiffies.h> void print_init_PCB(void) { printk(KERN_INFO "init_task pid:%d\n", init_task.pid); printk(KERN_INFO "init_task state:%lu\n", init_task.state); printk(KERN_INFO "init_task flags:%d\n", init_task.flags); printk(KERN_INFO "init_task runtime priority:%d\n", init_task.rt_priority); printk(KERN_INFO "init_task process policy:%d\n", init_task.policy); printk(KERN_INFO "init_task task group id:%d\n", init_task.tgid); } /* This function is called when the module is loaded. */ int simple_init(void) { printk(KERN_INFO "Loading Module\n"); print_init_PCB(); printk(KERN_INFO "Golden Ration Prime = %lu\n", GOLDEN_RATIO_PRIME); printk(KERN_INFO "HZ = %d\n", HZ); printk(KERN_INFO "enter jiffies = %lu\n", jiffies); return 0; } /* This function is called when the…arrow_forwardList at least five Operating Systems you know.

The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. Figure 1.27 (attached) illustrates the end-to-end transport of a message with and without message segmentation. Consider a message that is 106 bits long that is to be sent from source to destination in Figure 1.27. Suppose each link in the figure is 5 Mbps. Ignore propagation, queuing, and processing delays. a. Consider sending the message from source to destination without message segmentation. How long does it take to move the message from the source host to the first packet switch? Keeping in mind that each switch uses store-and-forward packet switching, what is the total time to move the message from source host to destination host? b. Now…arrow_forwardConsider a packet of length L that begins at end system A and travels over three links to a destination end system. These three links are connected by two packet switches. Let di, si, and Ri denote the length, propagation speed, and the transmission rate of link i, for i = 1, 2, 3. The packet switch delays each packet by dproc. Assuming no queuing delays, in terms of di, si, Ri, (i = 1, 2, 3), and L, what is the total end-to-end delay for the packet? Suppose now the packet is 1,500 bytes, the propagation speed on all three links is 2.5 * 10^8 m/s, the transmission rates of all three links are 2.5 Mbps, the packet switch processing delay is 3 msec, the length of the first link is 5,000 km, the length of the second link is 4,000 km, and the length of the last link is 1,000 km. For these values, what is the end-to-end delay?arrow_forward
