string을 이용한 File Path 분리 방법

string 형식의 파일 경로를 이용하여 File Path와 Name을 분리합니다.

File Path와 File Name 분리

#include <iostream>
namespace using std;

int main()
{
  string pullPath = "c:\\test\\test.tif";
  int find = pullPath.rfind("\\") + 1;

  string filePath = pullPath.substr(0, find);
  string fileName = pullPath.substr(find, pullPath.length() - find);

  cout << "Folder Path : " << filePath << endl;
  cout << "File Name : " << fileName << endl;
}

파일 확장자 바꾸기

#include <iostream>
namespace using std;

int main()
{
  string filePath = "c:\\test\\test.tif";
  string modExt = "ntf";

  int ext = filePath.rfind("tif");
  int name = filePath.rfind("\\") + 1;

  string dstPath = filePath.substr(0, name);
  dstPath += filePath.substr(name, ext - name);
  dstPath += modExt;

  cout << "Input Path : " << filePath << endl;
  cout << "Output Path : " << dstPath << endl;
}
