C 插入换行问题（作业）

Question

I'm writing a Java bytecode program using Jasmin and Yacc, and I want to use fprintf function to write "ldc \"%s\n\"\n" into aj file, but the resulting file would always lack the newline. For example:

    fprintf (fp,"ldc \"%s \\n\"\n",$6.val.get_char);

would be represented like this in the.j file:

    ldc "Hello" (no newline character \n added)

("Hello" is the corresponding string obtained from $6.val.get_char) How can I fix this issue? Thanks!

Edit: I've found out the issue, so the problem is solved now. Many thanks to @Rohan Bari for the help!

Edit 2: The solution turns out to be exactly the same thing I did earlier, so the following code:

     fprintf (fp,"ldc \"%s\\n\"\n",$6.val.get_char);

is already correct, the problem is simply located elsewhere. Still, Thanks for everyone who helped!

Answer 1

What if you do something like:

char text[] = "Hello";
fprintf(fp, "ldc \"%s\\n\"", text);

It outputs to the file:

ldc "Hello\n"
