What is & called?
Short answer. The address operator.
Does scanf("%s", name) need &?
No. The array name already gives the address.
Remember
| & gives the address |
| scanf stores at that address |
| No & for a string array |
Printf needs no ampersand. So why does scanf need one? Ampersand is the address operator. Scanf stores a value, so it needs the address of age. Ampersand gives the address. Scanf stores there. Strings need no ampersand.
