Scanning-Character-With-Space-In-C.txt

Note:- If you find any buffer error, you can add __fpurge(stdin); before scan function.
you`ve to add relative directory #include <stdio_ext.h> for fpurge function.
Hope it helps.

Method 1 : Using gets

Syntax : char *gets(char *str)

#include <stdio.h> 
int main() 
{ 
   char str[20]; 
   gets(str); 
   printf("%s", str); 
   return 0; 
} 
Note : gets() has been removed from c11. So it might give you a warning when implemented.
We see here that it doesn’t bothers about size of array. So, there is chance of Buffer Overflow.

Method 2 : To overcome above limitation, we can use fgets as :

Syntax : char *fgets(char *str, int size, FILE *stream)

Example : fgets(str, 20, stdin); as here, 20 is MAX_LIMIT according to declaration.

#include <stdio.h> 
#define MAX_LIMIT 20 
int main() 
{ 
   char str[MAX_LIMIT]; 
   fgets(str, MAX_LIMIT, stdin); 
   printf("%s", str); 
  
   return 0; 
} 

---------------------------------------------------------------------------------------------------------

Method 3 : Using %[^\n]%*c inside scanf

Example : scanf(“%[^\n]%*c”, str);

#include <stdio.h> 
int main() 
{ 
   char str[20]; 
   scanf("%[^\n]%*c", str); 
   printf("%s", str); 
  
   return 0; 
}
