Answer 1

Concept:

In the if statement, the program examines the test expression and only executes the statement(s) if the test expression returns True. The statement(s) are not executed if the test expression is False.

Given:

$x=0\\y=0\\z=1$

Find:

Find the values of x, y, and z after executing the program.

Solution:

10) $x=0,y=0,z=1$ (given)

The first statement $if(x)$ will return False as $x=0$.

Therefore, 'else' part will get executed.

$x+=1\\x=x+1\\x=0+1\\x=1$

Answer: $x=1, y=0,z=1$

11) Now updated values are $x=1, y=0,z=1$

The first statement $if(x)$ will return True as $x=1$.

Therefore, 'if then' part will get executed.

$y=x+2\\y=1+2\\y=3$

Answer: $x=1, y=3,z=1$
