By using Linux (Centos 7 or 8) develop a C program to apply the memory times and times, run with this shellprogram, then show the MemToal,MemFree,Active with excel file. Here are the codes for reference. Code no.1: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> main(int argc, char *argv[]) { void * p[100]; int i,times,msize; if(argc!=3) { times=20; msize=1024; } else { sscanf(argv[1],"%d",&times); sscanf(argv[2],"%d",&msize); if(msize>10240) msize=10240; msize=1024*msize; if(times>100) times=100; } for( i=0; i<times; i++) {…
Implement a simple version of the linux cat command in C++. Use the system calls open(), get() and close(). cat - reads a file as specified by the user and prints its contents. A typical usage is as follows: If from my terminal y run ./cat main.cpp the contents of main.cpp. will be printed. Your program cat can be invoked with one or more files on the command line; it should just print out each file in turn. Example: [terminal]$ ./cat main.cpp main2.cpp #include <iostream>using namespace std;int main(){cout << "Hello, World!"; return 0;}#include <iostream>using namespace std;int main(){cout << "Programming is great fun!";return 0;} As you can see content of main.cpp was printed first and the content of main2.cpp

Write a program called ReverseText.exe that takes two file names as command-line arguments. TheReverseText program should reads the characters from the first file and write them into the second file inreverse order. Test your program out using the small text file iso_8859-1.txt provided with thisassignment. Once you are confident that your program is working correctly, run it on the much larger fileWar_of_the_Worlds.txt uploaded along with this assignment. For example, when you use this program on the command line it should be like this:ReverseText.exe War_of_the_Worlds.txt War_of_the_Worlds_reversed.txt Remember, if you are using fgets(), it will only return one line of the book at a time. You willhave to go through the book multiple times and make frequent use of the rewind() function.HintYou can use the strlen() function (that is part of the string.h C Standard Library) to check thelength of the string you read in using fgets().

Write a shell program that renames all files in the current directory. It should remove all vowels from the filenames. For example, apple.txt should be renamed ppl.txt. If the resulting filename is an empty string, then the file should not be renamed.
Develop a python program that will determine the required mass of one compound based on three parameters: (1) compound name, (2) liters of solution, and (3) molarity The input should be in a single text file (input.txt). The required mass should be in a single text file (output.txt). Only two decimal places should be included in the output.txt. You can use the three files here https://filebin.net/twyx8f7q8lqr1cno to aid in doing the program -main.py includes the logic behind how output.txt is made based on the input.txt -compound.py. includes the strructure of compound class -periodictable.csv contains the information of the elements in the chemistry table of elements Example: ***input.txt*** compound,liter,molarity NH4Cl, 0.1, 2.5 NaCl, 0.5, 0.25 Na2CO3, 0.75, 1.25 ***output.txt*** 13.37 7.31 99.36
Write a programme called pgmReduce which takes 3 arguments:1. an input file (either ASCII or binary)2. an integer factor n, and3. an output fileand reduces the input file by that factor in each dimension. For example, if the invocation is:pgmReduce inputFile 5 outputFileand inputFile is a 13x17 image, then outputFile should be a 2x3 image in which only thepixels with row and column of 0 modulo 5 in the inputFile exist.

Create a simple java program that reads all the content in a .txt file, the user will enter the filename to be opened and once opened with any stream of choice, all the content in the file is printed to the screen. You are additionally expected to deal most common exceptions(See samples below) [HINT: DO NOT PROVIDE A PATH BUT RATHER ONLY OPEN THE FILE WITH RELATIVE PATH/FILENAME] Sample run 1: Enter filename: input.txt sample output 1: Hello files, I got the content NB: input.txt contains "Hello files, I got the content" as the data [See sample file] Sample run 2: Enter filename: myText.txt sample output 2: Invalid file : myText.txt could not be found in the current directory NB: myText.txt is not a valid file Requested files InClassDemo.java input.txt 1 Hello files, I got the content
