What is increment and decrement operators?

increment operator increments the variable by 1 at a time and decrement operator decrements by 1 in this we have two types increments pre_increment and post increment.

In pre_increment the original value is incremented by 1 and assign the new value

n=10

i=++n

then i =11

In post increment the original value is assigned and after it increments value by 1.

n=10

i=n++

then i=10

example:

k=5

i=k++ + ++k

i=?

ans:

in first k++ value is 5

second ++k value is 7

i=5+7=12
