How can I properly initialize this array?

[Bopaki]

I get this error when compiling:

In function `int main()':
error: variable-sized object `inputArray' may not be initialized

Execution terminated

  int main(){
	int maxSize=4;
	int inputArray[maxSize]= {45, 12, 76, 100} ;

[lastchance]

Either
const int maxSize=4;
or
int inputArray[]= {45, 12, 76, 100} ;
or
vector<int> inputArray = {45, 12, 76, 100};

Thanks last change here is the correct output:

C:\Dev-Cpp\Chapter11>daniwebBinaryTr
Display output using:
 a)inorder traversal
b)preorder traversal
c)postorder traversal

 Enter choice:a


12 45 76 100

C:\Dev-Cpp\Chapter11>daniwebBinaryTr
Display output using:

 Enter choice:b


45 12 76 100
