Need a Help about file handling

[rkv19]

I have a software written in VC++ and in the interface it accepts few values for different parameters. I want to do something like read a file which list of entries in to the interface instead of modifying one by one to get output , i ll read a file which all some 100 entries and read line by line and modify and run software to get results stored for each line as input in different output files. how can i do that in VC++ . I have found one thing in software that the parameters value when modified or stored gets changed in a file called sel.in which runs in software to generate output .
How to read a file each line by line and modify that in the software that parameters n run the software ?? Any help could be of great use !!!

std::ifstream input( "yourFile.txt" );
std::string line;

while ( std::getline( input, line ) )
{
    // Do something with that line...
}
