The problem is in these two pictures, please show me the source code~ 4.2. The binomial theorem can be written as 4.3....
Please show me the source code of this problem with C language (I only learned C before), thank you~ the Note that you must display 4.4 Write a program that computes the sum of all the negative integers in a list As input, the program is to read the data from the data file SUMNEG. 8.80.0 of integers. dugio DAT. The data file has the following format: ore (number of integers in list) line 1 dugdeer ) wo bne line...
C++ Can someone please help me with this problem- commenting each line of code so I can understand how to solve this problem using the C++ programming language? I really need help understanding how to create a file for the program to read. Do I create the file in Visual basic or create a text file? I have the code, just need to know how to create the file for it to read. #include<fstream> #include<iostream> using namespace std; int main()...
please write a C++ code Problem A: Word Shadow Source file: shadow.cpp f or java, or.cj Input file: shadow.in in reality, when we read an English word we normally do not read every single letter of that word but rather the word's "shadow" recalls its pronunciation and meaning from our brain. The word's shadow consists of the same number of letters that compose the actual word with first and last letters (of the word) in their original positions while the...
Can some help me with my code I'm not sure why its not working. Thanks In this exercise, you are to modify the Classify Numbers programming example in this chapter. As written, the program inputs the data from the standard input device (keyboard) and outputs the results on the standard output device (screen). The program can process only 20 numbers. Rewrite the program to incorporate the following requirements: a. Data to the program is input from a file of an...
I am really struggling with quantum. Can someone please help me with those questions 4.2. Using basic quantum concepts Pr 4.3 This problem reinforces your understanding of normalization, prob- ability densities, and mean (expectation) values. The ground state wave function for a particle in a wire is = (2/a)/2 sin(x/a). (a) Define the ground state wave function for the particle in a wire using Maple. Hint: see Appendix A. (b) Write down a mathematical expression for the normalization of the...

Python Problem, just need some guidance with the description, pseudocode and run time. I believe this is an 0-1 knapsack problem? Shopping Spree: (20 points) Acme Super Store is having a contest to give away shopping sprees to lucky families. If a family wins a shopping spree each person in the family can take any items in the store that he or she can carry out, however each person can only take one of each type of item. For example,...
"For two thousand years, codemakers have fought to preserve secrets while codebreakers have tried their best to reveal them." - taken from Code Book, The Evolution of Secrecy from Mary, Queen of Scots to Quantum Cryptography by Simon Singh.The idea for this machine problem came from this book.You will encrypt and decrypt some messages using a simplified version of a code in the book. The convention in cryptography is to write the plain text in lower case letters and the encrypted text in upper case...
This is for a Unix class. Please help me out. I am attaching a skeletal code of the program below, it just needs ti be filled in. Below is a skeletal code of the program. Fork a child process and then use the parent for reading and the child for writing.
