sscanf()-getting integer from a string

I want to extract the integer value form my file name, and there's no space between my file name
like Quote:
part1.dat or part12.dat
Code:
char src[20] = "part12.dat";
char dest[10];
int *i;

sscanf(src, "%[1-9]", &i);
printf("%d", *i);
could u plz correct my formatted text

 

Please refer to the following code...u will be able to undertand the mistake urself...always try to check the syntax of a function before using it....

Code:

const char * str = "part346.dat";
int value;

sscanf(str,"%*[^0-9]%d",&value);
printf("%d",value);
