在C和C++编程语言中,使用尖括号和在include语句中使用引号有什么区别,如下所示？

1. #include <filename>
2. #include "filename"

我在Visual Studio 2010中工作.我在Project Properties - > Linker - > General - > Additional Directories中添加了一个目录

如果我使用,项目编译

 "file.h"

但如果我使用,请不要

 <file>

请阅读我的代码,并帮我调试它.因为Dev-C++发现了很多错误....

#include<iostream.h>
#include<conio.h>
using namespace std;

struct iWorker{
       double salary;
}

double calSalary(iWorker worker){
    double money = worker.salary;
    return money;
}

int main(){
    iWorker worker;

    cout << "Enter salary: ";
    cin >> worker.salary;

    double salary = calSalary(worker, 0);
    cout << salary;

    getch();
    return 0;
}

和错误:

9: error: new types may not be defined in a return type
9: error: two or more data types in declaration of `calSalary'
 In function `iWorker calSalary(iWorker)':
11: error: conversion from `double' …

为什么"Dev C++"不支持C++中的iostream.h头文件..？如何在Dev C++中包含iostream.h头文件？
