How to copy an array integers to another variable?

Question

for example :

int var[]={9};

int someCopy = var[0]; // copy value, assume this is a wrong example

int newVar=18;

var[0]=newVar; // assign newVar to var[0]

how to print someCopy but the value of array var before doesn't change?

Answer 1

To print someCopy, you do :
cout<<someCopy;

Answer 2

Can you explain a little more in detail? As far as I can understand, you want var[0] to be 18(newVar) and someCopy to be 9 (var[0]'s original value), right?

Your current assignments do exactly this, and you can print someCopy without worrying about the value of var[0].

Answer 3

after array var value change by newVar. how to print current value of someCopy if the command to print, made after changing array var?
