make some crc check code, loop for multiple file (c++) - c++

Question

so i have this code for checking crc file named map.spak and compare the result with my specified crc result which stored in variable "compare"
int main(int iArg, char *sArg[])
{
char sSourceFile[MAX_PATH];
memset(sSourceFile, 0, sizeof(sSourceFile));
CCRC32 crc32;
crc32.Initialize(); //Only have to do this once.
unsigned int iCRC = 0;
strcpy(sSourceFile, "map.spak");
int compare = 399857339;
ifstream checkfile(sSourceFile);
if (checkfile){
cout << "Checking file " << sSourceFile << "..." << endl;
crc32.FileCRC(sSourceFile, &iCRC);
if(iCRC == compare){
cout << "File " << sSourceFile << " complete!\nCRC Result: " << iCRC << endl;
}else{
cout << "File " << sSourceFile << " incomplete!\nCRC Result: " << iCRC << endl;
}
}else{
cout << "File not found!" << endl;
}
system("pause");
return 0;
}
and now i want to make this code for multiple file
let's say the file name list stored in filelist.txt
the filelist.txt structure:
id|filename|specified crc
1|map.spak|399857339
2|monster.spak|274394072
how to make the crc check, loop for each file name
i'm not really good at c++ i only know some algorithm because i know PHP
c++ is too complicated
this is the full source included CRC source Source Code

I made several changes to your code. I removed guard headers since we use it only in header files. Old-fasioned memset has been replaced by operation on strings. I suspect that you need to pass char* to CCRC32 object hence sSourceFile is still const char*. I compiled code except parts with CCRC32.
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include "../CCRC32.H"
int main(int iArg, char *sArg[])
{
std::vector<std::string> filenames;
// TODO - populate filesnames (paths?)
CCRC32 crc32;
crc32.Initialize(); //Only have to do this once.
for (unsigned int i = 0; i < filenames.size(); i++) {
const char* sSourceFile = filenames[i].c_str();
unsigned int iCRC = 0;
int compare = 399857339; // TODO - you need to change this since you are checking several files
std::ifstream checkfile(sSourceFile);
if (checkfile) {
std::cout << "Checking file " << sSourceFile << "..." << std::endl;
crc32.FileCRC(sSourceFile, &iCRC);
if(iCRC == compare){
std::cout << "File " << sSourceFile << " complete!\nCRC Result: " << iCRC << std::endl;
} else {
std::cout << "File " << sSourceFile << " incomplete!\nCRC Result: " << iCRC << std::endl;
}
} else {
std::cout << "File tidak ditemukan!" << std::endl;
}
}
return 0;
}
