Multithreading c++

Please use comments and indentations, etc. *Problem statement*: Given a text file containing up to 100 lines, each representing a single-dimensional array and consists of 10 integer numbers. In additional to the main function, your program must contain at least two functions described as follows. The *first function* must read from the given file the next line (array elements) and store them in an array defined as a parameter. The *second function* calculates the sum of all array elements. This function is the one to be called by the created thread. The function main() accepts the following two command line parameters: the number of threads to be created (one thread for each file line_array) and the array length (number of values in each line). The function main() performs the following tasks in order. 1) Validate the count of the parameters and display a proper message in case of wrong count. 2) Validate the array length (specified by the second command-line parameter) against negative values 3) For all arrays whose count is specified by the second parameter: call the first function to copy the values from each line into an array and then display array elements at the beginning of a new line with proper messages. 4) Create the need number of threads (specified by the first command-line parameter) to call the second function for each array. 5) Waits for threads to terminate and then display the sum of each array with proper messages.
