我Vertex在Graph类中有以下结构:
struct Vertex
{
string country;
string city;
double lon;
double lat;
vector<edge> *adj;
Vertex(string country, string city, double lon, double lat)
{
this->country = country;
this->city = city;
this->lon = lon;
this->lat = lat;
this->adj = new vector<edge>();
}
};
当调用我写的方法时getCost(),我会一直得到同样的Unhandled Exception
访问冲突读取位置0x00000048
我无法弄清楚为什么.
的getCost()方法:
void Graph::getCost(string from, string to)
{
Vertex *f = (findvertex(from));
vector<edge> *v = f->adj; // Here is where it gives the error
vector<edge>::iterator itr = v->begin(); …我目前正在制作一个简单的PHP脚本来编辑JavaScript游戏的某些方面.当尝试使用表单将变量从脚本传递到游戏时,可变数据似乎不会传输.截至目前,该脚本旨在编辑游戏中一个玩家的RDG值.代码如下:
script.php的:
<html>
<head>
<title>Form</title>
</head>
<body>
<form method="get" action="tron2.html">
<p>What are your player 1's RGB values:
<input type="text" name="color1r" /> Red
<input type="text" name="color1g" /> Green
<input type="text" name="color1b" /> Blue </p>
<input type="submit" value="Submit" />
</form>
</body>
</html>
并且javascript中的代码部分分配了变量
<?php
$color1r = $_POST["color1r"];
$color1g = $_POST["color1g"];
$color1b = $_POST["color1b"];
?>
<HTML>
<HEAD>
<TITLE>
Tron2

<script>
var x = "<?= $color1r; ?>";
var y = "<?= $color1g; ?>";
var z = "<?= $color1b; ?>";
//more code for the …
