我试图在编译成功后在Windows 7中运行此代码。任何想法为什么它崩溃?我已经给它一个随机生成的二进制文件作为测试的输入,但一旦它开始,应用程序崩溃。为什么这个C++代码崩溃?

#include <cstdio> 
#include <cstdint> 
using namespace std; 

long getFileSize(FILE *file) { 
     long currentPosition, endPosition; 
     currentPosition = ftell(file); 
     fseek(file, 0, 2); 
     endPosition = ftell(file); 
     fseek(file, currentPosition, 0); 
     return endPosition; 
} 

struct frame { 
     uint8_t bytes[535];

struct spectralFrame { 
     uint8_t bytes[512];

struct spectralFrameWord { 
     uint16_t words[256];

     char *filePath = "C:\\Payload\\Untitled.bin"; 
     uint8_t *fileBuffer; 
     FILE *file = NULL; 
     file = fopen(filePath, "rb");

     long fileSize = getFileSize(file); 
     fileBuffer = new uint8_t[fileSize]; 
     fread(fileBuffer, fileSize, 1, file); 
     fclose (file); 
     long frameCount = fileSize/535; 
     frame *frames = new frame[frameCount]; 
     for(int i = 0, j = 0, k = 0; i < fileSize; i++) {

你为什么使用'stdio'而不是'iosream'? –

**从不**将字符串字面值存储在非const char *'中。我建议使用实际的C++功能,比如'std :: string'和'std :: vector'。 – chris

如果使用new[]你需要使用delete[],不delete。我在代码中看到三条违规规则。

看起来像c代码而不是C++。除了新的[] delete []尝试用valgrind运行它,它很可能会告诉你所有的坏东西。
