Short answer. The null character \0.
How many boxes for a 6-letter word?
7.
"Riya" in memory
| Index | Holds |
|---|---|
| 0 to 3 | R, i, y, a |
| 4 | '\0' |
Remember
| Strings end with '\0' |
| Size = letters + 1 |
Riya has four letters. Why five boxes? A C string is a char array. Boxes zero to three hold the letters. Box four holds the null character, which marks the end. Remember. Every string ends with null. Size is letters plus one.
