一、保存二进制

#include <iostream>
#include <fstream>int main(){
float* output = new float[100]();
ofstream fout("test.bin", ios::binary);
fout.write((char *)(&output[0]), sizeof(float));
fout.close();
return 0;
}

二、读取二进制

void Read()
{
string str = "test.bin";
float* freadbufs = new float[100];
std::ifstream ifs(str, std::ios::binary);
ifs.read((char*)freadbufs , sizeof(float) * 100);
ifs.close();
//delete freadbufs;
}
