  • difference between scanf("%s",s) and scanf("%[^\n]s",s)

when we say for scanf("%[^\n]s",s) It will read a string composed of any character except \n. It will end the string at the first \n it encounters.

while when scanf("%s",s) it will read only the string upto first space.

for example

int main()
{
     char str[100];
     char s[100];
    scanf(" %[^\n]s", str);
    scanf("%s",s);
    printf("%s\n", str);
     printf("%s", s);

}

if we give the input as 

lakshay saini (and press enter)

lakshay saini (and press enter )

so the result will be printed as 

lakshay saini

lakshay
