Below is the picture for the direction of my program and also
the part where I have problems with
![int main (int argc, char* argv[]) //variable declarations string fileName; vector <double> flightPath; vector <double> liftCo](http://img.homeworklib.com/questions/834d2ea0-4221-11eb-89c5-5f3169df7528.png?x-oss-process=image/resize,w_560)
I've already finished it and
my code works correctly. But what I need to do is to "read the file
name from the command line arguments" instead of the standard input
(cin) that I did for step 1. I'm not sure how to do that.

#include <iostream>

#include<string>
#include<fstream>
using namespace std;
//Function prototype
void readData(string fileName, vector<double>&
flightPath, vector<double>&
liftCoefficient);
int main(int argc,char* argv[])
{
vector<double> flightPath;
vector<double> liftCoefficient;
//Check argument contain in command line path
if (argc < 2) {
cout << "Error!!!No argument
in command line" << endl;
exit(0);
}
//Check more than 1 argument
else if (argc > 2) {
cout << "Error!!!Too many
arguments in command line" << endl;
exit(0);
}
//Otherwise argv contain file name
readData(argv[1], flightPath, liftCoefficient);
}

Write a complete C program that inputs a paragraph of text and prints out each unique letter found in the text along with the number of times it occurred. A sample run of the program is given below. You should input your text from a data file specified on the command line.

Objective: Use input/output files, strings, and command line arguments. Write a program that processes a text file by removing all blank lines (including lines that only contain white spaces), all spaces/tabs before the beginning of the line, and all spaces/tabs at the end of the line. The file must be saved under a different name with all the lines numbered and a single blank line added at the end of the file. For example, if the input file is given...

I am writing a program in C++, which requires me to read an input text file using command line argument. However, I am using xcode on my Macbook to write C++ program, and use terminal instead of command. How do you use int main(int argc, char** argv[]) to read an input file. My professor requires us not to hard code the text file name like .open("example.txt"); Thank you!
