Use of bool in C

The C99 standard for C language supports bool variables. Unlike C++, where no header file is needed to use bool, a header file “stdbool.h” must be included to use bool in C. If we save the below program as .c, it will not compile, but if we save it as .cpp, it will work fine.

int main() {   bool arr[2] = {true, false};   return 0; } in the above program, it will work fine as a C program.

#include <stdbool.h> int main() {   bool arr[2] = {true, false};   return 0; }
