- please please solve this problem urgently and perfectly. there may be more than 1 answerA binary executable file built with dynamic linking includes a call to printf(). The memory address of printf in the code... Cannot be known, it's a macro. Will be only determined at execution - it can be anything. Is recorded as a parameter for the CALL instruction. Is always stored in a register. Depends on the version of libc that compiler knows about.The Unix make utility allows the programmer to specify dependences among the separately compiled pieces of a program. If file A depends on file B and file B is modified, make deduces that A must be recompiled, in case any of the changes to B would affect the code produced for A. How accurate is this sort of dependence management? Under what circumstances will it lead to unnecessary work? Under what circumstances will it fail to recompile something that needs to be recompiled?
- The standard library function int fseek(FILE *fp, long offset, int origin) is identical to lseek except that fp is a file pointer instead of a file descriptor and return value is an int status, not a position. Write fseek. Make sure that your fseek coordinates properly with the buffering done for the other functions of the library.Write a program in C/C++ which is passed as command line argument a file name. Your program willread data from the file using read system call. The program will then pass the contents of the file to apipe and create a child process. The child process will read the file’s content from the pipe. The childprocess does two things to the file data: 1) it removes all integers from the pipe. 2) It changes the caseof all alphabets. The child process then writes the modified file data to the second pipe. The parent thenreads this data from the second pipe and writes the data (using write system call) to a new file whosename is also passed as command line argument. The input file from which the data will be read has nosize restriction.need help with this c program, please help with answer and instructions/explanation (I have a mac and use terminal)
- this is to be done in Assembly LanguageFor this problem, you will conduct experiments to explore the process of copying data from one file (File A) to another file (File B). You must provide your source code and a written report for this problem. Your source code must compile and execute without error on the CSE machines. You do not need to include the contents of File A or File B. 1. Write a small C program that copies data from a File A to a File B one byte at a time. You will examine the performance of this program in copying data from File A to File B. Create a graph to visualize performance of your program for copying files of different sizes. You must repeat this experiment using the following file sizes for File A: 1. 1MB 2. 2MB 3. 4MB 4. 8MB 5. 16MB 6. 32MB 7. 64MB 8. 128MB 2. Repeat this experiment three times. Rather than copying a single byte at a time, copy the file in 4, 64, and 1024 byte chunks. Generate a performance graph to visualize your results. Write a brief (1-2 page) report including 1. Your…2. Write a program that opens a file in read-only mode and maps the entire file into the virtual-memory address space using mmap. The program should search through the bytes in the mapped region, testing whether any of them is equal to the character X. As soon as an X is found, the program should print a success message and exit. If the entire file is searched without finding an X, the program should report failure. Time your program on files of varying size, some of which have an X at the beginning, while others have an X only at the end or not at all. Please write the program in C
- this question, assume you implemented and then compiled a code into a binary file mycode. Then you launch the gram mycode, It becomes a process and has a pid now. While the program is running, we can see information about the process in the directory /proc/pid. If we go to that directory and look at to the content of the file maps, we see information about the virtual memory usage of the process. Below is such an output for program mycode (in my system it has a pid=18854). In 'maps' file, each line of the output gives information about an address range in the virtual memory. The numbers are in hexadecimal. For example, the address range bf88a000-bf8ab000 contains the stack. The address range 08538000-0855b000 contains the heap. This program was executed on a 32-bit machine and virtual addresses are 32 bits. It is an Intel machine applying two level hierarchical paging. Address division scheme is: 10-10-12. Hence the Page size is 4 KB. #jaclude #include,You'll write a C++ program to demonstrate thread synchronization. Your main function should first create an empty file called *sync.txt*. Then it will create two separate threads: *Thread-A* and *Thread-B*. Both threads will open *sync.txt* and write to it simultaneously. *Thread-A* will write the numbers 0 through 9, a total of fifty-thousand times in nested `for` loops, then exit. In other words, print the numbers 0 through 9 over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line: ```text 0 1 2 3 4 5 6 7 8 9 ``` Somewhat similarly, *Thread-B* will write the letters A through Z fifty-thousand times in nested `for` loops, then exit. In other words, print the letters A through Z over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line: ```text A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ``` Do not write each line as one long string. You must write each character to the…Question R This is concerning files in c/c++ If I wanted to do the equivalent of a command-line rm followed by touch with one C function call, what would that be? Assume that pathToCleanse holds the path to that file. Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line. FastSEE MORE QUESTIONS
