im trying to continuously compare an image with itself. the command works fine when typed in the prompt, but when i run the program below, i get the output: "compare: unable to open image 'C:ob.jpg': No such file or directory. any ideas. thanks.

#include <iostream>
#include <string>

using namespace std;

int main()
{
	int a;
	
	for(a=1;a>0;a++){
	system("compare C:\rob.jpg C:\rob.jpg C:\3.bmp");
	
}}

Use two backslashes \\

BitByte is correct you need to use two backslashes in order for the system to see one of them. The compiler sees the first one as an escape sequence.

system("compare C:\\rob.jpg C:\\rob.jpg C:\\3.bmp");
