Question

If x = 3, y = 7, calculate the value of:X -= X++ - ++y​

Answer 1

Answer:

9

Explanation:

x=3, y=7

first we have to know the meaning of X++ and ++X.

x++ means X value is increased by 1 after this statement.

++x means ,X value is increased by 1 instantly.

x -=(some number) means X=x-some number.

first we have to calculate the value of expression.

x++-++y = 3-8 which is -5.

here X value is 3 only even after we added with 1, the value 4 will be reflected in next usage.

coming to y, it is ++y means immediate effect 7+1=8.

total expression value is 3-8 which is -5.

next final expression is X - = -5;

which is equal to X=x-(-5)

here X value is 4.

so answer is 4+5=9.
