How can I compare two strings without using strcmp in C++?

Compare Two Strings without strcmp()

1. First character (c) gets initialized to str1[0]
2. Second character (o) gets initialized to str1[1]
3. Similarly str1[2]=d, str1[3]=e.
4. Then a null terminated character \0 automatically assigned after the last character of entered string, so str[4]=\0.
