/Please/ don't offer us random fragments of code; offer us
complete (but small) compilable (unless of course your problem
is a compilation problem) programs. For example, the fragment
above doesn't have a declaration for `i` in it: what /else/
has been missed out?
Are you /sure/ you want to be using `scanf` here, rather than
`fgets`?
p is a ASCII code of integer but I need integer
for example if poli[i+2]='2' it puts p 50 (ascii code of '2')
but I need p=2 integer form, how can I do, please help
To convert a digit character into the corresponding value, you
simply subtract `'0'`, eg
int seven = '7' - '0';
C specifies that the digit characters are in order without gaps
(whereas it does /not/ do this for letters).
