Problem with the solution from the video

#1

Here is the link to the code for above problem–https://ide.codingblocks.com/s/11083
Here in line no. 19 it’s written visited[a[0]] = 0;
What does this line even mean?
I doesn’t make any sense to me , because ‘a’ is a character array and so a[0] is some character(not an index)…
Please explain this, because I’m absolutely unaware about this concept.

hello @chaturvedia336

when u use some character as vector/array index then its ascii value is used as index.

for example if i do visited[‘a’]=32;
then ascii value of ‘a’ is used (which is 97) and 32 is assigned at that index.
i.e visited[‘a’]=32 is equivalent to visited[97]=32
