You can name them whatever you want, but these are the normal names.
argc is non-negative. It gives the number of useful elements in argv.
If argc is positive, argv contains the program name. Then argv through argv[argc - 1] point to character arrays that contain the program's command line arguments.
For example, if I run a program at the command line, such as
argc will equal 2; and argv will compare equal to "unzip"; and argv will compare equal to "filename.zip".
When I open up a BASH shell and run perl -e 'print "Hello, world!\n"', perl gets an argc of 3, with argv pointing to "perl", argv pointing to "-e", and argv pointing to the string containing
print "Hello, world!\n"
(to represent that string in C syntax, that would be "print \"Hello, world!\\n\"")
Different command line shells use different ways of quoting arguments -- most separate arguments by spaces, with either single or double quotes used to allow arguments with spaces, as seen in the perl example -- this is all invisible to the program, though. In Windows I'd have to write, perl -e "print \"Hello, world!\n\""
Write a C program that should create a 10 element array of random integers (0 to 9). The program should total all of the numbers in the odd positions of the array and compare them with the total of the numbers in the even positions of the array and indicate ...
I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
the function that I created to find the ...
