Answer 1

Looks to me you have it backwards. If last is 'p' and the current is 'h' then you read 'ph'. Try:

if(c == 'h' && last == 'p')

If I enter phil. it returns gil. then.

Edit: and for the sake of reducing calls to the kernel, you definitely ought to read the entire string into a local buffer first using fgets.

Answer 2

Leif You right. I tested if more words and all words changed correctly.

Answer 3

it did work then the problem should be in the
last =0
c !
and yes I know I can use strings but i need this one just with characters and after that with strings

Answer 4

@Taw
