hey all...
i successfully learnt everything in the bitwise lesson and made a program:
the program runs successfully..Code:#include <iostream> #include <cstdlib> using namespace std; char in_use = 0; int *b = new int; int *c = new int; void check(){ for(int a = 0; a <= 8; a++){ if((in_use & (1 << a)) != 0){ cout << "The car " << a + 1 << " is in use...\n"; }else{ cout << "The car " << a + 1 << " is not in use...\n"; } } } void set(int pos){ in_use = (in_use | (1 << pos)); cout << "The car is now in use..."; } void unset(int pos){ in_use = (in_use & ~(1 << pos)); cout << "The car is now not in use..."; } int main(){ char x = 'y'; while(x == 'Y' || x == 'y'){ cout << "Welcome to tennisstar's Car Company..."; cout << "\n\n1)Take a Car for rent..."; cout << "\n2)Give a rented car back..."; cout << "\n3)See availability..."; cout << "\n4)Exit..."; cout << "\n\nEnter choice: "; int *a = new int; cin >> *a; switch(*a){ case 1: cout << "\n===\n\nChoose a car from 1 - 7 which you want to take: "; cin >> *b; *b -= 1; set(*b); break; case 2: cout << "\n===\n\nChoose a car from 1 - 7 which you want to give: "; cin >> *c; *c -= 1; unset(*c); break; case 3: cout << "\n===\n\n"; check(); break; case 4: cout << "\n"; system("pause"); return 0; default: cout << "\n===\n\nUNKNOWN OPERATION!!!"; } cout << "\n\n"; system("pause"); system("cls"); } }
but my question is: can we use a byte (i.e a char) to store something more than 8 values?
or maybe less?
can we use an encoding in which its 5 bits = 1 byte
or 9 bits = 1 byte
if yes...
how can we do so?
kindly help...
