如何在C++中读取二进制文件中的字符串？

ifstream file("binary_file.bin", ios::binary);
if (!file) {
    cerr << "Failed to open binary file." << endl;
    return;
}

file.seekg(16); // 假设字符串起始位置为偏移量为16的位置

char buffer[21]; // 20个字符 + 1个终止符
file.read(buffer, 20);
buffer[20] = '\0'; // 添加字符串终止符

file.close();

#include <iostream>
#include <fstream>
using namespace std;

int main() {
    ifstream file("binary_file.bin", ios::binary);
    if (!file) {
        cerr << "Failed to open binary file." << endl;
        return 0;
    }

    file.seekg(16); // 假设字符串起始位置为偏移量为16的位置

    char buffer[21]; // 20个字符 + 1个终止符
    file.read(buffer, 20);
    buffer[20] = '\0'; // 添加字符串终止符

    cout << "Read string from binary file: " << buffer << endl;

    file.close();

    return 0;
}
