In this case, the contents of array s remain unchanged because its values are not altered inside print_upper( ) The standard library function gets( ) is a classic example of passing arrays into functions Although the gets( ) in your standard library is more sophisticated, the following simpler version, called xgets ( ), will give you an idea of how it works

The xgets( ) function must be called with a char * pointer This, of course, can be the name of a character array, which by definition is a char * pointer Upon entry, xgets( ) establishes a for loop from 0 to 80 This prevents larger strings from being entered at the keyboard If more than 80 characters are entered, the function returns (The real gets( ) function does not have this restriction) Because C has no built-in bounds checking, you should make sure that any array used to call xgets ( ) can accept at least 80 characters As you type characters on the keyboard, they are placed in the string If you type a backspace, the counter t is reduced by 1, effectively removing the previous character from the array When you press ENTER , a null is placed at the end of the string, signaling its termination Because the array used to call xgets( ) is modified, upon return it contains the characters that you type argc and argv Arguments to main( ) Sometimes it is useful to pass information into a program when you run it Generally, you pass information into the main( ) function via command line arguments A command line argument is the information that follows the program's name on the command line of the operating system For example, when you compile a program, you might type something like the following after the command prompt, cc program_name where program_name is a command line argument that specifies the name of the program you wish to compile Two special built-in arguments, argc and argv, are used to receive command line arguments The argc parameter holds the number of arguments on the command line and is an integer It is always at least 1 because the name of the program qualifies as the first argument The argv parameter is a pointer to an array of character pointers Each element in this array points to a command line argument All command line arguments are strings any numbers will have to be converted by the program into the proper binary format, manually Here is a simple example that uses a command line argument It prints Hello and your name on the screen, if you specify your name as a command line argument

If you called this program name and your name were Tom, you would type name Tom to run the program The output from the program would be Hello Tom In many environments, each command line argument must be separated by a space or a tab Commas, semicolons, and the like are not considered separators For example,
