Java array size, length and loop examples

✅ Explanation: Most people try to use sizeof to find string length. That works for memory size, not for string length 🔹 Why sizeof is wrong here: • sizeof(str) counts total bytes • It also includes the '0' character • It does not stop at the end of the string 🔹 Why the loop is correct: • C strings end with '0' • The loop counts characters until '0' • This gives the actual length of the string • This is exactly how strlen() works internally 📌 Final takeaway • sizeof tells you how much memory i
