Answer 1

Anmol Kumar I'm don't know much about C but I'm not sure...
If I comment out that line i get the same output.
Veli-Matti strrev is a function. Use another variable name to avoid error in other compilers.

Answer 2

Well, strlen function doesn't include null character ('\0') while counting the characters in your string, so we've to explicitly tell the compiler about the null character by doing strrev[i] = '\0'

Answer 3

Thank you very much!

Strrev didnt work in sololearn last time I tried.
Some say its not a standard function.

But Ty for the tip!
