Code for two entries, skips second entry request

Re code below:
Question 1. After inputting data.name (say John Smith) and terminating with Enter, the data.actionCode cannot be entered. Sm is entereded instead. How can I change that?
Question 2. In the line "fwrite .." I don't understand the period in "...out),1,fptr..." . How much data has to go in, is already determined by the sizeof(... I have looked at differeten tutorials, still I don't understand.

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <strings.h>
    struct about
    {
        char name[35];
        char actionCode[2];
    };
   
int main()
{
    struct about data;
   
    printf("Concerns    : ");
    scanf("%s",data.name);   
       
    printf("Action Code : ");
    scanf("%s",data.actionCode);
   
    FILE *fptr;
    fptr=fopen("K:\\descrip", "a+");
   
    fwrite(&data,sizeof(struct about),1,fptr);
    fclose(fptr);   
    return 0;   
}

%s uses space as a separator, so to read "John Smith", you should ideally use fgets(), like

Code:

---

fgets( data.name, sizeof(data.name), stdin );

---

But you may want to remove the \n at the end of the line (see the FAQ for details).


Your fwrite() is fine.

Thank you. I need to do more homework.

After coding:

[code]
data.name = data.name.TrimEnd('\r', '\n');
data.actionCode = data.ActionCode.TrimEnd('\r', '\n');
[\code]

I get:

[Error] request for member 'TrimEnd' in something not a structure or union.

Question:

Does TrimEnd not like structures?

More like C# != C
String.TrimEnd Method (System) | Microsoft Docs

Right idea, but wrong language.

I usually do

Code:

---

char *p;
if ( (p=strchr(buff,'\n')) != NULL ) *p = '\0';

Is p the last character of the entered line of char?

Thank you for this solution. Excellent / nice and simple.
