Unwanted line after printing string on console and also writing it to file

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main()
{
    char name[25];
    char surname[25];
    File* F = fopen("string test.txt","w");

    if(F == NULL)
    {
        printf ("Error Creating File. ");
        exit(1);
    }

    printf("Enter name: ");
    fgets(name,24,stdin);

    printf("Enter surname: ');
    fgets(surname,24,stdin);

    //Here's the first problem:
    printf("\n\nName is: %s and Surname is: %s",name,surname);

    //Here's the second problem
    fprintf(F,"Name :%s and Surname :%s",name,surname);

    fclose(F);

    return 0;

}

After running the above code, I enter name "dog laptop" and Surname "hen pen" (without quotes).

In file and on console, I get output:

Name is: dog laptop
and Surname is: hen pen

My question is why did the cursor go to next line where as I didn't include a new line character?? And how to prevent this.

fgets includes the newline character in the string that it reads. Here's one way of getting rid of it. BTW, the size value passed to fgets should be the entire size of the array, which can be found with sizeof.

Code:

---

fgets(name, sizeof name, stdin);
size_t len = strlen(name);
if (len > 0 && name[len - 1] == '\n')
    name[--len] = '\0';

Wow, thanks.
That does it.

Does this mean fgets() does not initially include the NULL character?

No. It does include the nul character, after the newline. Otherwise we wouldn't be able to use strlen on it since strlen counts the number of characters until it hits the nul character.
