/* bool8_t is an unsigned 1 byte integer class that lets you to store 8 bools (8 bytes) in 1 byte. -------------------------------- - use [] to access each value. - use set(index, value) to assign value. -------------------------------- To use effectively in actual coding, you better define your boolean names that corresponds to each index of array using #define BOOL_NAME INDEX so you dont struggle with indexes created by Mustafa K. */ #include #include #include using namespace std; class bool8_t { uint8_t bits; public: // false as default bool8_t() { bits = 0; } bool8_t (bool status) { if (status) bits = 255; else bits = 0; } bool operator[](int i) { try { if (i >= 0 && i <= 7) { int mask = pow (2, 7-i); if ( (mask & bits) == mask) return true; return false; } else throw i; } catch(int x) { cout<< "Returning false: "<< '[' << i << ']' << " -> Invalid index\n"; return false; } } void set(int i, bool status) { if (i >= 0 && i <= 7) { int mask = pow(2, 7-i); if (status) bits = bits | mask; else { if ((*this)[i]) { if (bits > mask) bits -= mask; } } } } void print() { for (int i=0; i<8; i++) cout<< (*this)[i]; cout<< endl; } int _() {return bits;} }arr; int main() { cout<< "sizeof(bool) : "<< sizeof(bool) << endl; cout<< "sizeof(bool8_t) : "<< sizeof(bool8_t)<< endl << endl; cout<< "Setting i=6 to true...\n"; arr.set(6, true); arr.print(); cout<< endl; cout<< "Setting i=1 to true...\n"; arr.set(1, true); arr.print(); cout<< endl; cout<< "Setting i=3 to true...\n"; arr.set(3, true); arr.print(); cout<< endl; cout<< "Setting i=3 to false...\n"; arr.set(3, false); arr.print(); cout<< endl; cout<< "Setting i=6 to false...\n"; arr.set(6, false); arr.print(); cout<< endl; cout<< arr[9] << endl; return 0; }
