Hi to all!
VJ
Can any explain the answer of above program
VJ

Okay. If it's a USD then why is the function name 'main' always?...we can write any other name right?...and why is that the execution starts only from main function?
Because another library function (e.g. the __libc_start_main() function or the mainCRTStartup() function) needs to call the main() function, which you should define.

Z= 4*5
Z= 20 same goes for a 3*4= 12
Crct me
Mat
Which part I miss??
Lines:
1. a = 3
2. ++a two times means a = 5, so z = 25
Did you think like that?

But, I don`t have any materials

that's reference
S.
but the code is, strange

well
Here is an example
int a = 0;
int &r = a; // r is references
r = 9;
cout << a;
output:
9
klimi
& means reference afaik
Mihail
Use that if you want to make any modifications to the original value
Mihail
Was talking to the other guy
MᏫᎻᎯᎷᎷᎬᎠ
well
Here is an example
int a = 0;
int &r = a; // r is references
r = 9;
cout << a;
output:
9
That illustrate 70% of what you asked about
MᏫᎻᎯᎷᎷᎬᎠ
The other 30% is that references work as alias
MᏫᎻᎯᎷᎷᎬᎠ
And you can pass it as a functions arguments

well

int a = 0;
int &r = a; // r is references
r = 9;
cout << a;
output:
9
If you don't want to get into the details then here is the elevator pitch:
It's like pointers except that the dereferencing (the * operation) is done automatically.
MᏫᎻᎯᎷᎷᎬᎠ
MᏫᎻᎯᎷᎷᎬᎠ
Without the need of calling delete operator
MᏫᎻᎯᎷᎷᎬᎠ
It's a automatic variable
ojas
BTW, I mistakenly replied to you instead of the OP :p
Mihail
Sort of yes
MᏫᎻᎯᎷᎷᎬᎠ
Basically yeah
MᏫᎻᎯᎷᎷᎬᎠ
That's enough of understanding for you as a beginner
Mat
Sort of. Instead of copying the actual value of a into i, you create a reference to it

Y the values are not swapping in above program??
Dima
wtf
