write&read sd like fstream

in c++, we usually write file like this:

int int_1=1;
int int_2=2;
int int_3=3;
int int_4=4;
ofstream ofile;
ofile.open("file.txt")
ofile<<int_1<<" "<<int_2<<"    "<<int_3<<endl;
ofile<<int_4;
ofile.close;

and read file like this:

int a,b,c,d;
ifstream ifile;
ifile.open("file.txt")
ifile>>a>>b>>c>>d;  
/*reading file in order no matter whether the space between the variable is created by space/tab/new line. a=1, b=2, c=3, d=4*/

is there any library that can write/read txt file in sd card like fstream in c++?
for example like:
osdfstream ofile //for writing or
isdfstream ifile //for reading
because i already make save/load system in c++, and now i want to try that save system in arduino to make some project

only write. if should work on File of SD library. File class implements Print class
