Let’s start the discussion about error: ‘for’ loop initial declarations are only allowed in C99 or C11 mode in following Approaches.
This is because declaring variables inside a for loop was not valid C until C99 (the C standard published in 1999). You can either declare your counter outside the for as others have suggested, or use the -std=c99 flag to explicitly tell the compiler that you’re using this standard and that it should interpret it as such.

printf("%d",Arr[j]);I hope the strategies listed above work for you. Happy coding and come back again.
