Q1) True/False questions: Write T for true and F for false statement. If it is false, additionally write the reason describing why it is false. 1- In C++ compiler, the variable name can be started with underscore. 2- In switch-case statement, the default statement is executed even when one of the case statements is executed. 3- Do-While loop executes a block of statements at least one time. 4 Assignment operator is used to specify an initial value for a variable that cannot be changed during the main program. 5- In Boolean representation, a nonzero value can be set as true.

Q1) True/False questions: Write T for true and F for false statement. If it is false, additionally write the reasor
describing why it is false.
1- In C++ compiler, the variable name can be started with underscore.
2- In switch-case statement, the default statement is executed even when one of the case statements is
executed.
3- Do-While loop executes a block of statements at least one time.
4- Assignment operator is used to specify an initial value for a variable that cannot be changed during the
main program.
5- In Boolean representation, a nonzero value can be set as true.
Q2) Assume x=2, y=1 and z=2, write down the value of z after implementing the following statements:
1- Z*=x+y;
2- z= !(y>2)&&(y--);
3- z= 5+3%23;
4- z= (y=0) || (x=1/2);
5- z=++x - y++;
