Getting string as input from user-CodePudding

look at the code given below

#include <stdio.h>

int main()
{
    char str[20];
    printf("Enter a string : ");
    scanf("%s", str);
    printf("String : %s", str);
    return 0;
}

output will be,

Enter a string : Hello world

String : Hello

my question is why it take only first word as input?

Because that's exactly what the documentation says that the %s specifier should do:

Any number of non-whitespace characters, stopping at the first whitespace character found. A terminating null character is automatically added at the end of the stored sequence.

You can use the following methods

Method 1:

scanf("%[^\n]",str);

Method 2:

fgets(str, MAX_LIMIT, stdin);
