How to accept space in string in C in the given code - c

Question

Sorry about the previous code, I did not correctly interpreted the situation.
What's happening is the string is being stored with spaces but when i am trying to read it afterwards, The output flickers continuously (its like its reading it over and over again and printing it infinitely on itself.)
The records are stored in a file named record.dat
I am inserting image showing file contents stored after I input a new record in the file (Everything gets stored correctly here)
![These are the contents of record.dat right after i insert the new record]--> the image --> http://i.stack.imgur.com/YxGEd.png
and now when I try to look the details of this record on my application I get this.
![Output showing the record details but not entirely correct as " Finch" is missing] -- >> the image -- >> http://i.stack.imgur.com/zgmGY.png
and after this if i close the application and then start it again and try to read the previous data it shows this:
![This output is also flickering like before but now even the data is gone]-->> the image -->> http:// i.stack.imgur.com/ 4q0qb.png
(and just in case you are wondering -- the data is still there in the record.dat file -- all of it which i entered when i prevously created the record.)
I hope the problem is more clear now.....

Answer 1

The recommended solution is not to use scanf since scanf is also vulnerable to buffer overflows. In any case, you are not actually doing any formatting with the scanf call. You can use fgets to read the input into a string and specify the maximum number of characters that you allow. Use something like the following:
printf("\nEnter the name: ");
fgets(add.name, MAX_NAME_SZ, stdin);

Answer 2

You can use the %[^...] format specifier to read spaces into a string. Here's an example program that hopefully gives you something to work from.
#include <stdio.h>
int main()
{
char const* line = "This is a string, 10";
char text[50];
int number;
// Read up to 49 characters not including ',' to text.
sscanf(line, "%49[^,], %d", text, &number);
printf("%s, %d\n", text, number);
return 0;
}
Output:
This is a string, 10

Answer 3

I think you should provide an example of a failing situation or at least clean up the code and only give us the buggy part.
I see a lot of printf use without \n at the end which I know can be a problem (which may aswell be completely out of the subject here).
Since I've never used scanf I can't tell where your error is but maybe if you reduced your code to the acquisition of the user's input (-> the scanf part) then an attempt to display it (-> the part where your string gets truncated as it meets the first space) we could easily help you fix that problem faster and would be nicer to read.
