Ok, I am writing a program that I need to be able to save the values so you don''t have to type them in every time, this is a dos program and I know how to save the values to a file i just don''t know how to load them, any help would be appreciated.

What method are you using saving them? I guess knowing that will make it easier to give you an answer.

#include

int main(){
std::ofstream filevariable("test.dat", std::ios::app);
filevariable << "This text is appending to the file";
}


#include

int main(){
std::ofstream filevariable("test.dat");
filevariable << "This text is overwritting the file (i think)";
}

let me know if i''m doing anything wrong and if you can help, thanks

#include #include #include int main(){    std::ofstream ofile( "file.sav" );    std::string temp( "hi there" );    ofile << temp << std::endl;    ofile.close();    temp = "";    std::ifstream ifile( "file.sav" );	if( !ifile.is_open() )		return( 0 );    std::getline( ifile, temp );	ifile.close();    std::cout << temp << std::endl;    return( 0 );} 

Iostreams aren''t as fast as you could wish, so if you don''t need all their extra functionality you''re probably better off using the standard C function set. Iostreams are also C++ and thus they come with an portability and reusable code problem, fopen et al don''t. Least but not last fopen/fread/etc are easier to deal with in the beginning because you don''t have to care about classes, namespaces and fancy overloaded operators.

#include <stdio.h>...FILE *f;MY_STRUCT my_struct;/* For writing */f = fopen("abc.def", "wb");my_struct.foo = 2;...fwrite(&my_struct, sizeof(MY_STRUCT), 1, f);fclose(f);/* And for reading */f = fopen("abc.def", "rb");fread(&my_struct, sizeof(MY_STRUCT), 1, f);fclose(f);...
