This is probably a simple question, however I am new to C++ and I cannot figure this out. I am trying to load a binary file and load each byte to a vector. This works fine with a small file, but when I try to read larger than 410 bytes the program crashes and says:
This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.
I am using code::blocks on windows.
This is the code:
#include <iostream>
#include <fstream>
#include <vector>
using namespace std;
int main()
{
std::vector<char> vec;
std::ifstream file;
file.exceptions(
std::ifstream::badbit
| std::ifstream::failbit
| std::ifstream::eofbit);
file.open("file.bin");
file.seekg(0, std::ios::end);
std::streampos length(file.tellg());
if (length) {
file.seekg(0, std::ios::beg);
vec.resize(static_cast<std::size_t>(length));
file.read(&vec.front(), static_cast<std::size_t>(length));
}
int firstChar = static_cast<unsigned char>(vec[0]);
cout << firstChar <<endl;
return 0;
}
Thank you for your help!
