Create my control characters in string is % c not as output data, % s can be output, what is the problem?

CodePudding user response:

 Sq * s; int n; char a[20]; 
Printf (" both please enter the number: \ n "); 
The scanf (" % d ", & amp; N); 
Getchar ()//-- -- -- -- -- - the carriage return shielding here -- -- -- -- -- -- -- -- -- -- -- -- 
If (n & lt;=0) printf (" ERROR!" );

CodePudding user response:

Please refer to the "c + + fflush () function and rewind () function." "

CodePudding user response:

'ABC' no such character, only the string "ABC", a character is a byte, 'ABC' is the three characters,

If the string is judgment, consider this:

 typedef struct Lnode {
Char data [20]. 
Struct Lnode * next; 
} Sq.
