int Reserve(string &sss)

for(string::size_type id = 0;id != sss.size(); )
{
if(sss[id] == 'D')
{

if(sss[id]=='I')

return 2;

++id;
if(sss[id]=='O')

cout << "the function returns 3,DO is the KEY WORD~" << endl;
return 3;
break;
}
else
{
++id;
continue;
}
}
else if(sss[id]=='S')
{
++id;
if(sss[id]=='T')
{
++id;
if(sss[id]=='O')
{
++id;
if(sss[id]=='P')
{
cout << "the function returns 4,STOP is the KEY WORD~"<< endl;
return 4;
break;
}
else
{
++id;
continue;
}
}
else
{
++id;
continue;
}
}
else
{
++id;
continue;
}
}
else if(sss[id]=='E')
{
++id;
if(sss[id]=='N')
{
++id;
if(sss[id]=='D')
{
cout << "the function returns 5,DIM is the KEY WORD~"<< endl;
return 5;
break;
}
else
{
++id;
continue;
}
}
else
{
++id;
continue;
}
}
else return 0;
}
return -1;
}
我问的是:
当sss为DIM时,函数返回的是1吗?
当我把函数值赋给一个整数时却是0,想不通,帮忙解答下~
几行代码解决的问题，让你写得那么复杂，看到都晕。
int Reserve(string &sss)
{//对sss中的字符串查找保留字表
if(sss=="DIM")
return 1;
else if(sss=="TF")
return 2;
else if(sss=="DO")
return 3;
else if(sss=="STOP")
return 4;
else if(sss=="END")
return 5;
else
return -1;
}
