When I tend to output that string
But it output only one character.

Answer 1

Thank you codemonkey

Answer 2

codemonkey is it necessary to allocate space for null terminator in char array?
I ask this question because fgets() alone append the null terminator

Answer 3

Thank you codemonkey I got it😂

Answer 4

codemonkey how did you find that
//
Also, fgets() is a bit tricky:

char arr[3];
fgets(arr, 3, stdin);

If user inputs only one character 'a' and hits enter, fgets will read character 'a', read the new line and then append null terminator.
Your string will look like this:
arr = {'a' , '\n' , '\0'}
//
Can you provide some code for that to understand clearly

Answer 5

codemonkey I don't see(i.e didn't take place) "\n" newline 😂 in my output
when I enter "a" alone

Thank you codemonkey ☺

Answer 7

codemonkey suppose if run this code
#include <stdio.h>

int main() {
char char_array[3];
fgets(char_array,3, stdin);
printf("%s",char_array);;
return 0;
}
If we input nothing then the output was considered as
\n \n \0 // in ansii code 1010
Am I right code monkey?😅
