Okay there is a strange thing happening with my Visual Studio. The thing is that when i compile the program it compiles fine but then later on i realised that there is a difference in the way the declaration of the functions is done and the way i am using the functions. So it should give me a compile error.
PS: I copied the Visual Studio folder from my other computer to the laptop and started using it . So can this be an issue with this.
Microsoft compilers are notoriously buggy. I'd recommend using gcc (cygwin or mingw), personally.Quote:

I'm not even sure what the problem is...
Microsoft compilers are stable and generate good code, but can get confused and crash when doing heavy template code.
Do you have an example?Quote:

Also, what kind of difference in the function signatures are you talking about? Some parameters might be automatically converted to the right type, and if you're using prototypes with empty parameter lists, then anything goes.
This was one of the problems that i faced and it was pointed out here in the forum that the signatures of the functions that i was using is different and that it should not compile . But for me it was compiling as well as running.

Also just as a precaution i did the repair and reinstall feature of MSVS as well but to no avail.
I see what you mean.
All I can suggest then is making sure the file is saved, making sure you're compiling the right file (look at it in a different editor), and enabling warnings.Code:struct node * inorder(struct node *root, struct node *temp);
/* ... */
struct node * inorder(struct node **root, struct node *temp)
{
/* ... */
}
i think i am facing another wrath from my compiler in the current program as well. I really dont understand what can be wrong with it. But its giving me 11 errors in a function that contains hardly 10 lines.
[insert]The list of errors is as follows:Code:
#include <stdio.h>
#include <stdlib.h>
#define n 10
int parseint(char *a);
int main(int argc , char * argv[])
{
int i, j;
//int n = parseint(argv[1]);
int a[n];
int k;
char *b = "123";
k = parseint(b);
printf("\n %d", RAND_MAX);
for(i = 0;i<n;i++)
{
int temp = rand()%10;
printf("\n%d", temp);
a[i] = temp;
}
for(i = 0; i<n ; i++){
for(j = 0; j<n-1 ;j++){
if(a[j] > a[j+1]){
int t = a[j];
a[j] = a[j+1];
a[j+1] = t;
}
}
}
printf("\n Array in ascending order");
for(i = 0; i< n;i++){
printf("\n %d", a[i]);
}
getch();
return 0;
}
int parseint(char *a)
{
char *b;
int n;
int i = 0;
int sum = 0;
char c = *a;
b = a;
n = c - '0';
b++;
if(*b != '\0')
{
i++;
sum = sum*10 + n + parseint(*b);
}
if (i > 0)
return sum;
else
return n;
}
[insert]Please suggest something what should i do... I seem to be going mad nowCode:

Should i remove the application and try reinstalling it ? I like VS because i am pretty comfortable with it.
getch() is an ancient, unportable function which you shouldn't be using. :) See the FAQ.
The third rule of programming: almost all of the time, it's you who is at fault and not the compiler. I'm not sure what the first and second rules are right at this moment, but if pressed I could make something up. :pQuote:

Anyway, here's your problem.
You do that, and then try to doCode:#define n 10
The preprocessor happily turns this intoCode:int n;
and the compiler throws its hands in the air and gives up.Code:int 10;
It's not Visual Studio that is in error; it's you.
Problem: getch is undeclared. Cause: You haven't included the proper header. Solution: Obvious.
Problem: Syntax error. Cause: You have a macro named n. Solution: Change macro or variable name.
Also, you don't pay enough heed to warnings. Your previous code that you linked in this thread spewed out lots of warnings:
Warning 6 warning C4047: 'function' : 'node **' differs in levels of indirection from 'node *' test.cpp 71

Umm, right. And which header file would one include for getch() in Visual Studio? ;)Quote:

If you can't find it, remove it :p
I'll have to remember that the next time I'm googling something. If you can't find what you're looking for, remove the web browser . . . ? Not sure how helpful that would be. :p
For what it's worth: SourceForge.net: Pause console - cpwiki
[edit] Also, I should mention that standard practice is to declare macros in all uppercase, for this very reason. If normal identifiers and macros both have the same naming conventions, it's hard to tell one from the other. [/edit]
conio.h obviously. :)Quote:
