How to run an exe using c prog

[Ujjwal]

Hi All,
I am new to this forum. I am in need of a program in C that runs an exe file in Windows.
While googling I found the code below :

1.

#include<stdlib.h>
#include<stdio.h>
int main()
{
 (void)system("C:\\Windows\\notepad.exe");
 return 0;
}

The above code compiles successfully in Borland Turbo C. But it fails to run Notepad.

2

#include<stdlib.h>
#include<stdio.h>
void main()
{
 int result;
 result=system("C:\\Windows\\notepad.exe");
 printf("%d",result);
}

The above code on running gives -1 as output. Why am I getting -1.

My OS Windows XP
Borland Turbo C Compiler

Please help.

Your biggest problem is that your 20+ year old 16-bit (FAT) compiler doesn't have a clue about your 32-bit (NTFS) operating system.

Get a proper compiler for your actual OS.
Microsoft Express Downloads - Visual Studio Express and SQL Server Express
Code::Blocks

Actually Salem... the filesystem shouldn't matter, the OS should be handling that.

His biggest problem is that starting with Windows 2000 notepad.exe is in the system32 folder.

system("c:\\windows\\system32\\notepad.exe") should work.

But yes, he does need to get rid of that dinosaur compiler....

Perhaps you are right . As I said earlier it compiles successfully but the editor (Borland) fails to run the exe .I manually ran the compiled exe from command prompt then it opened the notepad successfully.

No path is not the problem. See this post

I Think the real problem is with the compiler as both of you suggested.

Thanks for your replies.
