Can someone outline the "best practice" (if any!) to handle newline in ANSI-C standard library functions?
I had some confusion with these functions recently related to char array and char pointer. puts(), printf(), strcpy(), strncpy(), memset().
I seem to understand their basic use, but got quite confused on some situations.
1) For unknown reason, sometime I got output:
With the memset() function inserted, I always got the correct output. But, I do not see memset() is combined with these strncpy()/strcpy() very often.
2) The 4 puts() are in a row, but sometime they gave extra blank line that seems come from extra newline (especially in the next example), but I read puts() only appends newline at the end.
Here is another example where I tested with printf() and puts():
I must have missed important rules to use these functions.
so I'm asking my question with "best practice" to narrow down my struggle if that is reasonable. Thanks.
Dear All,
I have to develope some C functions in Unix for a Magic program. The original MSE code which compiles the attached C program uses a +z option, but the cc compiler don't know this. The complete command in the compiler script is 'cc -c -Aa +z myfile.c'. The warning message is 'The -z... (4 Replies)
can somebody explain about the ANSI C vs POSIX. say i was using open and fopen, i know that open is POSIX, and fopen is ANSI C. i read that that POSIX is a system call and ANSI C is like a standard library function. wouldn't the fopen function has to call on open function anyway to open any kind...

Is it not a healthy practice to mix C and C++ standard I/O functions together
e.g.
string name; // this is a declared instance of the string class in C++
printf("\nPlease enter your name: ");
cin >> name;
I did something similar in a program Im designing, and used it several... (1 Reply)

I need to run a cronjob and in the cronjob I execute a script that if there is an error produces standard error so I do
