I find that there is no native bool type. People either use int or char - though it seem that int might be more frequently used than char? Is this true?
My first impulse was to use char as it is a smaller data type, but there something I've missed? Is int better for boolean values, and if so - why?

C does not have boolean data types, and normally uses integers for boolean testing. Zero is used to represent false, and One is used to represent true.
Nope, bools are designed to only store a 1 or a 0.
Syntax to Declare Boolean Data Types in C:To declare a boolean data type in C we have to use a keyword named bool followed by a variable name. bool var_name; Here, bool is the keyword denoting the data-type and var_name is the variable name. A bool takes in real 1 bit, as we need only 2 different values(0 or 1).
Boolean values still behave as integers, can be stored in integer variables, and used anywhere integers would be valid, including in indexing, arithmetic, parsing, and formatting.
There is a _Bool in C99, and a bool if you include stdbool.h.
If you don't have it (a decently modern compiler), use int, it's usually the fastest type. The memory savings of using char are likely negligible.
