Question

I have a textfile that contains this line:

    C:\Program Files\app\

I want to read it to become this:

    C:\\Program Files\\app\\

I know how to read the file in visual c++, but how to add a slash() everytime it founds the slash.

    char str[200];
    fstream file_op("C:\\path.txt",ios::in);
    file_op >> str;
    file_op.close();

Answer 1

The simplest way to do this is through loop:

char newPath[MAX_PATH];
int newCount = 0;
for(int i=0; i < strlen(str); i++)
{

    if(str[i] == '\')
    {
        newPath[newCount++] = str[i];
    }
    newPath[newCount++] = str[i];
}

Please note that you cannot change a file in place. You will have to write new strings to a new file. I am not using boost or any other library because those are not part of VisualC++ by default and your tag says you need this for VisualC++
