String to integer

I want out of a

Code:

char szBuffer [5]

so ultimately a string in which a number is that number read out and store in an Integer. Does anyone have a clever solution?

 

If only you could figure stands inside an
atoi () or () atof take.
atoin spits an integer, a float atof out.

If in a specific location is also only one number can
number = szBuffer [2]; make

 

Cool, thanks.

 

Better,

Code:

Number = szBuffer [2] - ' 0';	

Code:

Number = szBuffer [2] - ' 0';

otherwise you get the value of a character ....

 

If you want to read several things from NEM machs string, so:

Code:

char * string; 
. 
. 
. 
scanf (string, "% d", & number);
. 
. 
.

 

Thank you for the many replies.

 

due to this story:
someone knows how to use strtol, int to string convert? (with, for example?)

 

@ Peter pan
strtol for string to long int

Otherwise, look at the manpage

Code:

Strtol (3) Linux Programmer's Manual strtol (3) 

NAME 
strtol - convert a string to a long integer. 

SYNOPSIS 
# include <stdlib.h> 

long int strtol (const char * nptr, char ** endptr, int base); 

DESCRIPTION 
The strtol () function converts the string in nptr to a 
long integer value according to the given base, which must 
be between 2 and 36 inclusive, or be the special value 0th 

The string must begin with an arbitrary amount of white 
space (as determined by isspace (3)) followed by a single 
optional `+ 'or` -' sign. If base is zero or 16, the 
string may then include a `0x 'prefix, and the number will 
be read in base 16, otherwise, a zero base is taken as 10 
(decimal) unless the next character is `0 ', in which case 
it is taken as 8 (octal). 
The remainder of the string is converted to a long int 
value in the obvious manner, stopping at the first charac 
ter which is not a valid digit in the given base. (In 
bases above 10, the letter `A 'in either upper or lower 
case represents 10, `B 'represents 11, and so forth, with 
Z 'representing `35th) 

If endptr is not NULL, strtol () stores the address of the 
first invalid character in * endptr. If there were no dig 
its at all, strtol () stores the original value of nptr in 
* endptr (and returns 0). In particular, if * nptr is not 
`\ 0 'but ** endptr is` \ 0' on return, the entire string is 
valid. 

RETURN VALUE 
The strtol () function returns the result of the conver 
sion, unless the value would underflow or overflow. If at 
underflow occurs, strtol () returns LONG_MIN. If an over 
flow occurs, strtol () returns LONG_MAX. In both cases, 
errno is set to ERANGE. 

ERRORS 
ERANGE The given string was out of range, the value con 
verted has been clamped.
