I've done the while loop part where it displays the number, and I am logged into the linux server so I am able to test this out, but does anyone know how to code for the instructions to read "hello.out n" in the command line and then execute my code?

This is what I currently have:

#include

using namespace std;

int main( int argc, char *argv[] )

{

if( argc == 2 ) {

cout

}

else (argc != 2);

{

cout

exit(0);

}

{

int argv[1];

cout

cin >> argv[1];

int sum = 0;

int i = 1;

while(i

{

cout

sum = sum + i;

i++;

}

cout

return 0;

}

}

Objective: Write a program to demonstrate while loops and compute the sum. The main purpose of this homework is to review your understanding of loops. Problem: Using C++, write a program using a while loop to count down from a number and calculate the sum of the numbers starting at 1 and counting to n. The iteration number, n, is read directly from command line, e.g., Jexecutable iteration. Requirement Program must be written in the file hw0/hw0.cpp of the linux server program.cs.uh.edu. The file hw0.cpp is already created in the folder hw0 of your account. Program will be tested in the server. Compile your file as "gt+ hw0.cpp -o hello.ou". If you don't have the executable file hello.out, your score will be 0. Run your file with at least three types of input argument a. Should print "Error" if argument number is not exactly two. For example /hello.out b. Should print "Error" if the argument is negative. For example: /hello.out -2 Error c. For a positive number argument, it should print the numbers ranging from 1 to the argument in each line and "Sum is x" as the last line. For example: /hello.out 5 should print: 1 2 3 4 5 Sum is 15
