Can someone please explain increments and decrements to me? I only started learning coding yesterday and this is kinda confusing

Question

Increments and Decrements in JavaScript

Answer 1

Increment increases variable's value by "1", decrement decreases by "1".
int a = 0
a++
Value of a == 1

Answer 2

@Vaibhav Jadhav
In your example in both cases the result is 11.

a=10
System.out.println(++a)
result 11

a=10
System.out.println(a++)
result 10

Answer 3

increment:
i++ is the same as i=i+1;

decrement:
i-- is the same as i=i-1;

u increase or decrease your variable by 1

Answer 4

suppose a=10
if a++
system.out.println(a);

result=10

if ++a
system.out.println(a);

result=11
