Assert macro: It denotes a tool to ensure that expected conditions are true at assert statement location. If condition does not meet, then program displays error message and aborts. The assert definition is been included in program with statement “#include<cassert>”. The statement “assert(bool_expr)” is inserted to use “assert”, the “bool_expr” denotes a Boolean expression that should be evaluated to true. The assert statement denotes a macro, that is similar to function. The assert macros can be disabled by adding “#define NDEBUG” before include statement. Given statement: x = ( x * y / z ) Explanation: The given statement denotes an expression with variables “x”, “y” and “z”. It updates the value of “x”. The value of “z” should not be zero. If the value becomes zero, then it displays division by zero error.

Program Plan Intro

Assert macro:

It denotes a tool to ensure that expected conditions are true at assert statement location.

If condition does not meet, then program displays error message and aborts.

The assert definition is been included in program with statement “#include<cassert>”.

The statement “assert(bool_expr)” is inserted to use “assert”, the “bool_expr” denotes a Boolean expression that should be evaluated to true.

The assert statement denotes a macro, that is similar to function.

The assert macros can be disabled by adding “#define NDEBUG” before include statement.

Given statement:

x=(x*y/z)

Explanation:

The given statement denotes an expression with variables “x”, “y” and “z”.

It updates the value of “x”.

The value of “z” should not be zero.

If the value becomes zero, then it displays division by zero error.

In this assignment, you will implement a multi-threaded program (using C/C++) that will check for Prime Numbers and Palindrome Numbers in a range of numbers. Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…
