对于一项作业，我需要允许用户输入和编辑数组中结构的数据。目前虽然我根本无法让程序调用我的编辑屏幕，更不用说编辑数组中结构的数据了。当我选择编辑程序时，程序会循环回到数据输出功能。
我的编辑画面原型是
item Edit_Screen(item one);
应该是从我的搜索功能调用
void titlesrch_bar(item s[], int limit)
{
int ctr= 0;
string title = "XXX";
string resp = "XXX";
cout << " Enter a Title to locate: "; getline(cin, title);
for( ctr = 0; ctr < limit; ctr++ )
{
if( s[ctr].BookTitle == title)
Data_Output( s[ctr].BookTitle, s[ctr].ISBN, s[ctr].Author, s[ctr].EXPenroll, s[ctr].price, s[ctr].reqNreq, s[ctr].UsedUnused);
else
{
cout << " Error: Order Not Found" << endl;
transition();
}
}
cout << " Do You Want To Edit This Order(Y/N): "; getline(cin, resp);
if(toupper(resp.at(0))=='Y')
item Edit_Screen();
}
函数被命名为
item Edit_Screen(item one)
{
string resp = "XXX";
string buffer = "XXX";
do {
cout << endl;
cout << endl;
cout << endl;
cout <<" COLLEGE BOOK ORDERING SYSTEM" << endl;
