Regarding scanf

[Parul Bagadia]

Probably i know the answer of this ; but i'm not so sure.
Ok, in one program i used newline character('\n') after the format specifier ; and the next line was not getting executed.... untill i enter one more value...
It indicated that; may be because, value gets stored in the memory location only when pointer ; or you may say & sign in case of scanf is used.
Is it because of the same reason; as i thought or something else?

Let's see the code. A description of the problem can't be used reliably.

Here is the code;
ahd below that is the output of that......
after scanf is executed the remaining code doesnt execute.

#include<stdio.h>
#include<conio.h>
void assign();
void check();
int c;
void main()
{
int choise;
do{
printf("\nEnter your choise from the given menu:\n 1.Assign\n 2.Check \n 3.Exit\n");
scanf("\n%d",&choise);
switch(choise)
{
case 1:
assign();
break;
case 2:
check();
break;
case 3:
break;
}
}while(choise!=3);
}
void check()
{
int i;
printf("%d",&c);
i=c+1;
printf("%d",i);
printf("\n%d",&i);
}
void assign()
{
printf("\n Enter the value of c:\n");
scanf("\n%d\n ",&c);
}
Enter your choise from the given menu:
1.Assign
2.Check
3.Exit
1

Enter the value of c:
34





3

Enter your choise from the given menu:
1.Assign
2.Check
3.Exit
Press any key to continue

Go to Google, and type in "man scanf" there. Now read the manual pages that appear. Especially read the portion that tells you what happens when you type in a whitespace character in the format string. FYI, '\n' is whitespace as well.

Thanx for that; but can you tell me what is FYI?

Sorry, abbreviation for "For your information". I tend to use the abbreviations FYI and NB (Nota Bene) a bit more than I should, I suppose.
