Will atoi() convert the convertible characters in a string? I mean, in this problem,

post[20]="822*/3+2"

, if i write

atoi(post)

, will it convert the numerical characters to int? And how about the operators?

Here's what the man pages have to say:

int atoi(const char *nptr);

DESCRIPTION
The atoi() function converts the initial portion of the string pointed
to by nptr to int. The behavior is the same as

strtol(nptr, (char **) NULL, 10);

except that atoi() does not detect errors.

You really should write a small program and see what it returns.

Ok, i'll try strtol(), correct me if i'm wrong.

nptr is the string
what about (char**)NULL?
and that 10

You really should try Googling..What your asking is can be found by typing

c programming strtol

in your browser.
