b=++a + a++ + --a
++a= 3+1=4
a++= 4+1=5 (but here a=4 because post increament first assign then increment)
--a= 5-1=4
b=4+4+4
b=12

[hasshamkhan-gmji]

Start with a = 3.
++a increments a before its value is used, so now a is 4.
a++ uses the current value of a (4) and then increments it, so now a is 5.
--a decrements a before its value is used, so now a becomes 4.
Now, put it all together: b = 4 + 4 + 4 = 12.

[ZareenFatima-go]

b is d
[Process completed (code 6) - press Enter]

[abhi]

The answer is 9.Bcz ++a=4 and a++=4 and at last + --a=1(this + in front of a is the reason for the decrement of 2 ).

[CashHotel-xlih]

Explanation is ++a = 4, a++ = 5, --a = 4 that is totally 13, hope everyone understands

[shivampal]

On Online c compiler
Answer is 13
And on turbo c
Answer is 9
Depends upon compiler bits system.

[ImRoshan-seby]

Using increment and drecrement function

[PrachiGajbhiye-fc]

Ans is 9 because pre increment mean first add and post increment means assign and then add
So b=++a+a+++--a
b=4+3+2
b=9

[cutiboys]

I'm a begineer and thing the answer is b=10,
Because
++a = 4, a++ = 4, --a = 2
B=4+4+2=10

[krjnbpp]

Undefined behaviour (depends on compiler)

[Fine_Mouche]

In newer comp: (3+1) + (4+1) + (5-1) = 4 + 5 + 4 = 13 // in old : (3+1) + 4 + (4-1) = 4 + 4 + 3 = 11

[asrafulfardin]

The variable a is initialized with a value of 3.
The expression ++a increments the value of a by 1, resulting in a being equal to 4.
The expression a++ uses the post-increment operator, so the value of a (4) is used in the expression, but then a is incremented to 5.
The expression - -a decrements the value of a by 1, resulting in a being equal to 4 again.

Hence, 4+5+4 = 13

[himankjeshwar]

12 or 9 depends on compiler mostly its 12 in most compilers

[SyedUmar-ewtw]

answer is 13
a=3
++a=4
a++=4(after next step it ill be 5)
and - -a=5-1=4
total answer is=4+5+4=13...

[learncode]

its totally depend on compiler Answer is not Define

[Nisar]

First it will increase by one that I 3+1=4 and + then 4+1 =5next it will decrease that is 5-1=4 at last it will print 4

[uditjec]

In turbo C compiler answer would be 9 but in gcc compiler answer would be 12

[kurakulasyamsundar]

++a gives 4 now a=4 then a++ means 5 then a is still 4 because it is first assigned and then got increment so it's still 4 and now --a means 3 . So the answer is 4+5+3=12

[sandeepsvlog]

Return 0 kyu nhi type kya kya yhi error he or iska answer 13 he

[-smokem]

Correct answer is 12 which the clang compiler (version 14.0.6) returns. However, the gcc (version 12.2.0) returns 13. b = 4 + 4 + 4
