The document provides C++ variable declarations for one integer variable named 'number', two double variables 'signal' and 'pi' (with 'pi' initialized to 3.14159), and two boolean variables 'flag' (initialized to false) and 'bit'. There is no main() program required and optional comments are included. It also advises to press the enter key before saving.

1. Write C++ variable declarations to create one int variable called number, two real variables
called signal and pi where pi is initialized to 3 .14159, and two bool variables called flag and bit
where flag is initialized to false. No main () program is necessary and comments are optional. Be
sure to strike the Enter key before you click on the Save button.
Solution
int number;
double signal;
double pi=3.14159;//initialized
bool flag=false;//initialized
bool bit;
