Index variable of any array should be integer constant.
but in this case i is not constant so it is a error

Answer / rajesh

It will give segmentation fault(core dumped) - runtime error

This is not the way of declaring an array...a slight change
in program can correct it. Code below...

int main()
{
int i=0 ,a[i];
// i = 0;
a[i] = 10;
cout<< a[i] << endl;
return 0;
}
output : 10

please initialise the value of i before putting it in array
a[i]..this code will work fine and will give the output as 10.
