为什么此代码不允许我在文件中搜索？

Question

我是一个完整的初学者，希望有更多知识的人可以看一下这段代码，并告诉我我要去哪里了？当我尝试搜索时，它说即使输入文件中存在的名称也找不到记录。除此之外，我在文件中输入的名称将被保存而没有首字母。例如：哈里就是哈里。这是2000多行程序的摘录。渴望有人帮助。谢谢。

using namespace std;

int main()
{
    int search;
    cout<<"\n\n\t\t\tName: ";
    cin.ignore();
    getline(cin,(customer.name));
    cout<<"\n\t\t\tPhone Number: ";
    cin>>customer.phone_no;
    cout<<"\n\t\t\tAge: ";
    cin>>customer.age;
    ofstream file("data.txt",ios::app);
    file<<customer.name<<"\n"<<customer.phone_no<<"\n"<<customer.age<<"\n\n";
    file.close();
    cout<<"Press 1 to search";
    cin>>search;
    if(search==1)
        searchbyname();



}

            temp++;
