How to convert a boolean to integer? (type casting)Ī type cast is basically a conversion from one type to another.Īn object declared as type Bool is large enough to store the values 0 and 1. Printf("Value at index 1 of array is %d",arr) ! (NOT): takes 1 operand return true if operand is false and false if operand is true.

|| (OR): returns true if either or both of the operands are true else false.

& (AND): takes 2 booleans returns true only if both operands are true else false.

We can use logical operators with boolean. To declare a variable as a boolean use: bool variable_name = true Note: it needs only 1 bit but takes 8 bits due to the structure of the computing system. The above code will give size 1 for bool, so generally bool store a 1 byte of memory. MemoryĪn object declared as type Bool is large enough to store the values 0 and 1. In actual computing systems, the minimum amount of memory is set to a particular value (usually 8 bits) which is used (all bits as 0 or 1). Due to two possible values, it needs only 1 bit. In computer science, the Boolean data type is a data type that has one of two possible values, either TRUE or FALSE. Standard logical operators AND (&), OR(||) and NOT(!) can be used with the Boolean type in any combination. Note if we do not include the above header file, then we need to replace bool with _Bool and the code will work as usually. You can learn about _Bool here in detail. To use boolean, a header file stdbool.h must be included to use bool in C.īool is an alias to _Bool to avoid breaking existing C code which might be using bool as an identifier. In C, boolean is known as bool data type. C programming language (from C99) supports Boolean data type (bool) and internally, it was referred as _Bool as boolean was not a datatype in early versions of C.
