What is the use of a[i]='\0

in character input video 3 we have done a[i]!=’\0’;
why?

hi @arnavsingh88888888_c06bfcee2a553263,
character array needs to know where to stop, so its terminated by ‘\0’ symbol
say you want to store “abc” and array is of size 10 then u need to store the symbol so that it prints till “abc” not whole size (10) with garbage
