发现FLLEwritea文件里面没内容,什么原因?/
[解决办法]
FLLEwritea 好像没看到有这个文件？
[解决办法]
ofstream outaa(".cpp"); //这个？？？
[解决办法]
for(int i=0;ch!= '$ ';i++)
{
printf("input the strings %d \n",i+1);
cin > > ches; ==> ch ??
out < < ches; ==> ch??
printf("if you want to go on ,press any key but '$ ' \n");
cin > > ch ;
}
[解决办法]
在读文件之前,先关闭文件试试:
......
for(int i=0;ch!= '$ ';i++)
{
printf("input the strings %d \n",i+1);
cin > > ches;
out < < ches;
printf("if you want to go on ,press any key but '$ ' \n");
cin > > ch ;
}
out.close();
vector <string > v;
int i,j;
ifstream in("FILEwrite.cpp");
while(getline(in,line))
v.push_back(line);
......
