Scanf --------- to be continued

1. Do not read Spaces

# Include <iostream> # include <stdio. h> using namespace STD; int main () {char C [50]; scanf ("% s", c); printf ("% s", C ); return 0 ;}

2. spaces can be read.

Character ^ can be used to describe the complement set. When the ^ character is placed as the first character of the scan set, it forms a complementary set of commands consisting of other characters, indicating that scanf () only accepts unspecified other characters.

 

# Include <iostream> # include <stdio. h> using namespace STD; int main () {char C [50]; scanf ("% [^ \ n]", c); // printf ("% s ", c); Return 0 ;}
