I have 2 strings like this:
In these 2 cases I want to get "File1.txt" and "File2.txt" and put them to a new string.
I need the same method so I suppose I have to find the Last "/" in the string and then
put the rest to a new string.
What method and approach could be used to do this ?
Code:std::string Line1 = "c:\Folder1\File1.txt";
std::string Line2 = "c:\Folder1\Folder2\File2.txt";
std::string::rfind()
Use std::string.rfind and add them together.
Line1 += Line2;
And as a side note, "C:\Folder1" is wrong. It should be "C:\\Folder1". For every \, you need to specify two (\\), since \ is an escape character (\n means newline for example).
Yes okay, I will try that out.
Thanks !
You can also use a single '/' instead of double '\\' for path separators:
Code:"C:/Folder/File.txt"
Only works with API and I wouldn't actually recommend it. Proper filenames uses backslashes (\) and not forward slashes. Someday Microsoft might just change it.
What do you mean "only works with API"?Quote:

Windows filesystem uses "\" and not "/". Windows API translates "/" into "\".
Microsoft Windows supports both, no matter if it's translated or not. To demonstrate:Quote:

This was compiled with Visual C++ 2005 Express on Windows XP Home SP2.Code:#include <stdio.h>
int main ( void )
{
char word[100];
const char * const filepath = "C:/Documents and Settings/JCK/My Documents/data.txt";
FILE * fdata;
fdata = fopen( filepath, "w+" );
if ( fdata ) {
fputs( "Hello, world! This is a sample text file.\n", fdata );
rewind( fdata );
while ( fscanf( fdata, "%99s", word ) == 1 ) {
printf( "read from file: \"%s\"\n", word );
}
fclose( fdata );
remove( filepath );
}
return 0;
}
/** as expected, the output:
read from file: "Hello,"
read from file: "world!"
read from file: "This"
read from file: "is"
read from file: "a"
read from file: "sample"
read from file: "text"
read from file: "file."
**/
Filepaths with forward slashes will be opened fine.
I'm not suggesting using forward slashes outside of source code.Quote:
