What is the alternative character combination for a double quote character in C / C ++?

I have not had a directory of Kernighan and Ritchie C for many years, but I remember that there was a page that talked about how to enter characters that are not available to you. (WAY back that day, some keyboards lacked characters like ", ~, etc.).

To be clear, let me give an example. I'm not looking for a way to get quotes in strings, but instead I want to replace this:

printf("foo");

with this:

printf([alternate sequence]foo[alternate sequence]);

For the curious, I have an automated process that involves generating C / C ++ code, but a commercial tool (closed source) included quotes in its data streams, and it’s clear in the documentation that they don’t provide a way to avoid them.
