replacing scanf with fgets

Dear All,

I realise there are many threads concerning the use of fgets, however I am still having difficulty after having read many of the previous threads!

Put simply, I have to replace every use of scanf in my code with fgets. For example, here is a typical example of the use of scanf in the current code:

/* example */

Code:

---

 
int quest;

  printf("Are you sure you wish to exit the Menu?\n");
  printf("Press 1) to return to Options or 2) to exit the Menu: ");
  scanf("%d",&quest);

---

/* end example */

Any ideas how I replace scanf with the use of fgets? Any advice would be greatly appreciated.

Cheers.....

What exactly are you having difficulty with.

char* fgets(char* string,int number,FILE* stream)

fgets will retrieve number bytes from stream and place in buffer pointed to by string. To read from the keyboard make stream stdin.Because you control the number of bytes read there is no chance of your buffer overrunning and causing problems.
Next to parse the string use sscanf(). This works like scanf() except instead of taking its input from the keyboard it will take its input from the buffer filled by your fgets call.
There are a multitude of code snippets illustrating this on this site. Look at a few of them.

In the furture please use Code Tags.

Code:

---

int quest;
char int_holder[10];

printf("Are you sure you wish to exit the Menu?\n");
printf("Press 1) to return to Options or 2) to exit the Menu: ");
quest = atoi( fgets( int_holder, 10, stdin ) );

---

>quest = atoi( fgets( int_holder, 10, stdin ) );
Not the best idea... what happens if fgets() returns NULL? Crash and burn me thinks... :)

thanks for your replies everyone – I shall try to implement the suggested solutions this evening and let you know how I go.

as for code tags – the link you provided is no longer working. where can I find this information?

much appreciated hammer ..... code tags will now become part of the routine.

No problem!

Nice to hear :)
