sscanf

Question

what is sscanf? what does it do?

Answer 1

Below is the format of sscanf:
int sscanf(char *str, char *fmt, arg1, arg2,...)

sscanf scans the provided str according to the format in fmt, and stored the resulting values through arg1, arg2, etc. These arguments must be pointers.

Instead of standard input (stdin), it reads data from the source string, which is provided as the first argument. The other arguments are just like that of scanf.

Answer 3
