The difference between CodeBlocks and VC2010?...

See more:

VC10.0

I found an interesting stuff:

when programming using Code::Blocks, the following program(C) runs smoothly:

#include <stdio.h>
#include <stdlib.h>

int power(int m, int n);

main()
{
    printf("This is a program for exponientiation\n");
    int i;
    ...

but, when i copied this piece of code into VC2010, its debugger detected several errors and i have to revise it into the following form to make it running smoothly in VC2010:

#include <stdio.h>
#include <stdlib.h>

int power(int m, int n);

main()
{

    int i;
     printf("This is a program for exponientiation\n");
     ...

and this kind of form (where printf() has been placed after the definition of variables) works also okay in Code::Blocks, who could tell me why this happened?
Does the Code::Blocks enjoys a better fault tolerance or, does the VC2010 requires more strictly about the code form?


PS: a friend told me that the first form is more likely a C++ one, perhaps CodeBlocks is less sensitive to the difference between C and C++?...
