Example 12.7 Write a program that will receive a filename and a line of text as command line arguments and write the text to the file. Figure 12.7 shows the use of command line arguments. The command line is F12 7 TEXT AAAAAA BBBBBB CCCCCC DDDDDD EEEEEE FFFFFF GGGGGG Each word in the command line is an argument to the main and therefore the total number of arguments is 9. The argument vector argv[1] points to the string TEXT and therefore the statement fp = fopen(argv[1], "w"); %3D opens a file with the name TEXT. The for loop that follows immediately writes the remaining 7 arguments to the file TEXT.
