write() function in c does not write the data with spaces into file

Question

write() function in c does not write the data with spaces into file

Code:

#include<stdio.h>
#include<unistd.h>
#include<fcntl.h>
#include<sys/stat.h>
#include<sys/types.h>

int main()
{
int fp;
char fnm[50], data[1000]="";

printf("Enter the file name: ");
scanf("%s",fnm);
printf("\nEnter file data:\n");
scanf("%s",data);
fp=open(fnm,O_CREAT | O_RDWR | O_APPEND,0777);

if(fp==-1)
{
printf("\nError in opening file");
return 0;
}
write(fp,data,1000);
close(fp);

return 0;
}

Output:

./a.out
Enter the file name: r

Enter file data:
rrrr yyyyyyyyyy yyyyyyyyy

$ cat r
rrrr

Can someone help how can I accept the complete input using write() function itself

Answer 1

We can take string input in C using scanf(“%s”, str). But, it accepts string only until it finds first space.

There are 3 method by which C program accepts string with space in the form of user input.

Method 1 : Using gets
Syntax : char *gets(char *str)

Method 2 : we can use fgets
Syntax : char *fgets(char *str, int size, FILE *stream)

Method 3 : Using %[^\n]%*c inside scanf
Example : scanf(“%[^\n]%*c”, str);

Method 2 is recommended.

edit:
change the second scanf with
fgets(data, 1000, stdin);

Answer 2

If I replace the 2nd scanf by fgets(data,1000,stdin)
The program terminates after accepting the file name & is creating a blank file.

Answer 3

Thank you for your answers. I have changed the code by using fgets to take input from user.
But the code is skipping the fgets and executing the remaining part of the program.

I checked on few websites, majority of them sed that fgets is taking a new line character which is generated by the 1st scanf.

M not sure how to remove this new line character.
