printf("\% %d", ...) is not working as expected

Question

printf("%d \% %d = %d", 4, 3, 1);

I was expecting this to print "4 % 3 = 1", but instead it prints "4 %d = 3". How can I make this print the expected result? Does "\" not disable the "%" following it?

Answer 1

%% is the pattern to escape a %, so write printf("%d %% %d = %d")
