Printing " (double quote) in C

问题

I am writing a C code which reads from a file and generates an intermediate .c file. To do so I use fprintf() to print into that intermediate file.

How can I print " ?

回答1:

You can use escape symbol \" For example

puts( "\"This is a sentence in quotes\"" );

or

printf( "Here is a quote %c", '\"' );

or

printf( "Here is a quote %c", '"' );

回答2:

If you just want to print a single " character:

putchar('"');

The " doesn't have to be escaped in a character constant, since character constants are delimited by ', not ". (You can still escape it if you like: '\"'.)

If it's part of some larger chunk of output in a string literal, you need to escape it so it's not treated as the closing " of the literal:

puts("These are \"quotation marks\"\n");

or

printf("%s\n", "These are \"quotation marks\"");
