程序没有输出预期的结果:反向输出字符串

Question

#include <stdio.h>

char* main()
{
 int n=0;
 int c=0;
 int i;
 char bbc[80]={0};
 printf("Please input a string:\n"); 
 scanf("%s",bbc);
 char temp[200]="0";
 int length = strlen(bbc);
 for(i = 0; i < length+1; i++)
 {
  temp[i] = bbc[length - i];
 } //end for
 temp[i] = '\n';
  printf("%s",temp);
 return temp ;
}

Answer 1

#include "stdafx.h"

#include <iostream>
using namespace std;
 
int main()
{
	int n=0; 
	int c=0;
	int i;
	char bbc[80]={0};
	printf("Please input a string:\n"); 
	gets(bbc);
	char temp[200]= {0};
	int length = strlen(bbc);
	for(i = 0; i < length; i++)
	{
		temp[i] = bbc[length - 1 - i];
	} //end for
	temp[i] = '\n';
	printf("%s",temp);
	return 0 ;
}
不过要注意数组溢出的问题，如果输入的字符串超长~

Answer 2

std::wstring wstrName = L"Honny_yeyh";
std::reverse(wstrName.begin(), wstrName.end());
std::wcout<<wstrName<<std::endl;

Answer 3

可以取得上面的返回值吗? int是可以的,char不知道行不行

#include <Windows.h>
//#include <iostream>
#include <stdio.h>

int main(int argc, TCHAR* argv[])
{
 
 STARTUPINFO si = {sizeof(si)};
 PROCESS_INFORMATION pi = {0};
 TCHAR szApp[MAX_PATH] = {TEXT("C:\\1\\process\\m1.exe")};
 if(CreateProcess(szApp, NULL, NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi))
 {
  WaitForSingleObject(pi.hProcess, 4000);
  DWORD dwRet = 0;
  //hProcess=GetExitCodeProcess(pi.hProcess, &dwRet)
  if(GetExitCodeProcess(pi.hProcess, &dwRet))
  {
    //printf("return value= : %d characters.\n",dwRet);
    printf("return value= : %s characters.\n",dwRet);
   //printf<<"return value = "<<dwRet<<endl;
  }
  TerminateProcess(pi.hProcess,1);

  CloseHandle(pi.hThread);
  CloseHandle(pi.hProcess);
 }
 else
 {
  //cout<<"error: "<<GetLastError()<<endl;
  return;
 }
 return 0;
}

Answer 4

无法取到，跨进程是无法访问内存的，更何况进程的空间已经被释放了。你可以使用共享内存获得这些值。

Answer 8

int是api的返回值

麻烦把正确答案设为解答。

下面这个INT可以
int main()
{
int n=0;
int c=0;
int i;
char bbc[80]={0};
printf("Please input a string:\n");
gets(bbc);
char temp[200]= {0};
int length = strlen(bbc);
for(i = 0; i < length; i++)
{
temp[i] = bbc[length - 1 - i];
} //end for
temp[i] = '\n';
printf("%s",temp);
return 0 ;
}

Answer 9

不好意思，我说的不是字符串，是这个API GetExitCodeProcess
