Magtheridon96: Refer to my post in the thread.
Also, this doesn't do 150000 shuffles :v

Awesome I will test it when I have time!

 

[D.O.G.]

1) It doesn't works on my XP. It says it isn't valid Win32 application.
2) What is purpose of this tool?

 

[Nestharus]

Hm... I compiled it on Windows 7 64 bit ; \, but I believe that I compiled it as a 32 bit app... sooo

 

[Magtheridon96]

In Release Mode?

edit
This thing needs msvcp110.dll to run.
I don't have that DLL file for some reason.

You can totally fix this by using different functions ;v
getline is the culprit.

Nes, since most people are having problems using this, I took the liberty of rewriting your code in C.

#include <stdio.h>
#include <cstdlib>

int main(int argc, char* argv[]) {
	unsigned int length = 0;
	unsigned int size = 64;
	char* buffer = (char*)malloc(size);
	FILE* file;
	char c;

	if (1 == argc) {
		return 0;
	}

	file = fopen(argv[1], "rb");

	if (file) {
		/*
		*	Put all characters into a buffer.
		*	This will stop upon:
		*
		*		- Reaching the end of the file
		*		- Hitting a carriage return character.
		*		- Hitting a linebreak character.
		*/
		while (true) {
			c = fgetc(file);

			if (c != EOF && c != '\r' && c != '\n') {
				if (size == length) {
					buffer = (char*)realloc(buffer, size += 64);
				}
				buffer[length++] = c;
			} else {
				break;
			}
		}
		fclose(file);

		/* Skip if line has length = 0 */
		if (length) {

			int shuffles = 50;
			int swap;

			/* Seed random number generator */
			srand((int)&argc);

			/* Shuffle */
			while (shuffles--) {
				for (unsigned int i = 0; i < length; i++) {
					swap = rand() % length;

					c = buffer[i];
					buffer[i] = buffer[swap];
					buffer[swap] = c;
				}
			}
			
			/* Write file */
			file = fopen("TextShufflerOutput.txt", "wb");
			for (unsigned int i = 0; i < length; i++) {
				fwrite(&(buffer[i]), 1, 1, file);
			}
			fclose(file);

			/*
			*	These calls are highly unportable.
			*	They are only being used because this 
			*	is meant to run *only* on Windows.
			*/
			system("notepad.exe TextShufflerOutput.txt");
			system("del TextShufflerOutput.txt");
		}
	}

	return 0;
}

The .exe attached is only 7KB too
