Thread: sprintf + fprintf

Hi, I have a question that may be dealing with efficiency in programming:

What is the conceptual difference between writing to files in the two steps:

Code:

fp = fopen(full_filename, "w+");

char str[128];
sprintf(str, "%d ", Variable);
fprintf(fp, str);

and using directly fprintf in the following way:

Code:

fprintf(fp ," %d", Variable);

Is the first better for memory saving in some way? I usually use the second option, but starting wondering when I saw other people using option 1.

Thank you in advance

Thanks for the quick reply

That helped
