The difference between scanf/gets/fgets in C

Function: Also gets the string.

Difference:

scanf encounters a space/carriage return/tab that the input ends,

However, the space/carriage return/tab key will remain in the input buffer . It is common to use GetChar () to handle the funeral of scanf; If you want to clear the residue, you can use Fllush () to clear the cache.

get can receive a space/carriage return/tab key , Enter the end of input , but in Linux gets is a dangerous function, because there is no overflow check, in window gets is the upgrade version is safe.

　　　　use ' \ n ' instead of '/' and the enter will not remain in the input buffer .

Fgets can be a perfect substitute for get, just a different grammar.

Same point:

scanf gets the string after the completion of the automatic addition of ' \ ';
