Why does while (s[n]) stop?
Short answer. The null character is 0, which is false.
What does "Surat" give?
5.
Remember
| Loop until '\0' |
| Count as you go |
Can you find a string's length without strlen? Yes. Start n at zero. While s of n is not null, add one. The null character is zero, so the loop stops there. Surat gives five. Remember. Loop until null. Count as you go.
