How sacnf can accept whitespace?

Question

I am trying to enter a string with white space in the C using %s option but it does is only taking till first white space. Any suggestion how to enter a string with white space in the scanf?

Answer 1

#include <stdio.h>

int main (int argc, char const *argv[])
{
    char name[20];
    scanf("%[^\n]s",name);
    printf("%s\n", name);
    return 0;
}

Answer 2

it is better to use "fgets()" instead of scanf()
but if you really want to use scanf() only, then repley "%s" with "%[^\n]" ie. "scanf("%[^\n]", buff);"
this will take the input until a "\n" (new line) encountered.

But I would suggest go with fgets(), because there is no check for buffer overflow in scanf().
