Question

VC++6.0运行这段程序时编译和连接没有错误 执行时会出现xx.exe已停止工作，求大神指教

#include <iostream>
#include <stdlib.h>
#include <string>
#include <fstream>
#include <sys/types.h>
using namespace std;
int main(string sname)
{
sname="/abcd/ef";
string src = sname;
string src2;
char prova[40]="";
char app[40]="";
int ix = src.size() - 1;
//size()可以求得字符串的长度
while ((src[ix]!='/')&&(ix>=0)) ix--;
int ix2=0;
ix++;
while (ix<src.size()) {
prova[ix2]=src[ix];
ix2++;
ix++;
}
src2=prova;
printf("src2=%s\n",src2);
return 0;
}

#include <iostream>
#include <stdlib.h>
#include <string>
#include <fstream>
#include <sys/types.h>
using namespace std;
int main(string sname)
{
sname="/abcd/ef";
string src = sname;
string src2;
char prova[40]="";
char app[40]="";
int ix = src.size() - 1; //size()可以求得字符串的长度
while ((src[ix]!='/')&&(ix>=0))
ix--;
int ix2=0;
ix++;
while (ix<src.size())
{
prova[ix2]=src[ix];
ix2++;
ix++;
}
src2=prova;
printf("src2=%s\n",prova); //这里！
return 0;
}

试试它，应该是字符串string和char数组之间的赋值有问题，自己找找！
