A little help here guys am confused with outputs...

Question

int a =4;
int b =6;
b=a++;
Console.WriteLine(b++); // note the (b++)
// Output 4 but how?

int a =4;
int b =6;
b=a++;
Console.WriteLine(++b); // note the (++b)

//Output 5 (for this i understand but the earlier am confused can i get some explanation😥

Answer 1

An easy way to remember how these operators behave involves these two rules:

• If the operator appears 'before' the operand, the operation will occur 'before' the expression has been evaluated.

• If the operator appears 'after' the operand, the operation will occur 'after' the expression has already been evaluated.

Here is another example,

Postfix increment a++ will add 1 to a:
int a = 12;
a++;
Console.WriteLine(a); // 13

Postfix decrement a-- will subtract one:
a = 12;
a--;
Console.WriteLine(a); // 11

++a is called prefix increment it increments the value of 'a' and then
returns 'a' while a++ returns the value of 'a' and then increments:

int b = 12;
Console.WriteLine(++b); // 13

while
b = 12;
Console.WriteLine(b++); // 12

Answer 3

Steven Ambroce post increment is first used the store value then update the value in calling same expression again with same variables so in first code script
b =a++ means store value of a++
The value of a=4 so post increment will use first stored value which is 4 so b = 4 is store at end.
Then in print statement you are doing post increment which use stored value first then increment so b store value is 4 so output is 4 for first code script.

In second code pre increment used which first increment then use so value is increases and 5 is came as output
