Given these definitions what (if anything) is wrong with the following?

Question

```
int b[5] = {3,4,5,6,7};
for (int j = 1; j <= 5; j++)
tripler(b[j]);
```

Consider the following function definition:
```
void tripler(int& n)
{
n = 3*n;
}
```

a) Nothing is wrong with either bit of code.
b) There are not enough initializers for the array.
c) There is an illegal index in the loop.
d) There are too many initializers in for the array.
e) The call to the function requires different syntax

Answer 1

d) There are too many initializers in for the array., and c) There is an illegal index in the loop.

There is nothing wrong with the array declaration and initialization. However, the loop has both an illegal index (5) and very likely an intent error. The loop runs 1 through 5 instead of the C++ idiom 0 through size-1.
