我试图在C中创建一个函数,它将交换两个字符串变量,但出现问题,程序崩溃.

请看看我的代码并告诉我我犯了哪个错误:

#include <string.h>

void strswap(char name1[], char name2[])    // to swap two strings
{
    int lengthname1, lengthname2;
    lengthname1 = strlen(name1);
    lengthname2 = strlen(name2);
    char temporaryname1[100];
    char temporaryname2[100];
    int x;
    int y;
    // till just the declaration
    for (int x = 0; x < lengthname1; lengthname1++) {
        temporaryname1[x] = name1[x];
        name1[x] = ' ';
    }
    // copying the value of name1 in temporaryname1
    for (int y = 0; y < lengthname2; lengthname2++) {
        temporaryname2[x] = name2[x];
        name2[x] = ' '; …

问题是,<p>并且<h1>出现在同一条线上,无论我做什么,它们都无法居中.

HTML

<div class="container">
  <div class="row" id="appSummary">
    <h1>Why This App Is Awesome</h1>
    <p class="lead">Summary, once again, of your app's awesomeness</p>
  </div>
</div>

#appSummary{

我正在开发第三人称射击游戏。我找到了这段代码。但我不能对此毫无意义。首先，它将四元数与“Vector3.forward”相乘，编译器没有显示任何内容。另外你能告诉我这段代码的主要逻辑吗？我知道死记硬背代码不是一个好习惯。那么你能给我解释一下代码吗？Quaternion.euler 的作用是将 euler 更改为四元数。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraFollow : MonoBehaviour {
    [SerializeField]
    Transform target;
    [SerializeField]
    float distance;
    [SerializeField]
    float targetheight;

    private float x = 0;
    private float y = 0;

    void LateUpdate()
    {

        y = target.eulerAngles.y;

        Quaternion rotation = Quaternion.Euler(x, y, 0);
        Debug.Log(rotation);
        transform.rotation = rotation;

        var postion = target.position - (rotation *Vector3.forward* distance + new Vector3(0, -targetheight, 0));
        transform.position = postion;
    }
}
