Project Objective:

1. get familiar with the process of completing a programming project.

2. learn how to use and manipulate arrays.

3. understand precedence and associative rules.

4. use program selection: if, if-else, switch statements.

5. use basic loops (while, do-while, for) for repetition.

全优代写 - 北美Essay代写,Report代写,留学生论文代写作业代写In this project, you will design and implement a program to evaluate an arithmetic

expression. The arithmetic expression will contain only integers, both positive and negative, and

the following six basic binary operators +, -, %, /, *, and ^ as well as parentheses ().

Your program should read in the expression from an input file. The input file has a

COMP2355 lab11 solution

C++多線程程序作業代寫,實現多線程任務分配

In this lab you’ll implement a program which uses multiple threads to divide up a simple problem

into independent sub-tasks. Source code for this lab is supplied in Lab11Source.zip .

double ThreadedSum(int numThreads, size_t arraySize);

You’ll find an empty function definition in main.cpp in the supplied source code. This function

should :

for the stack, so make sure you allocate it on the heap (free store).

2. Run numThreads threads, each of which initializes an approximately equal portion of the

sure you handle round-off correctly if arraySize is not an even multiple of numThreads. Each
