软件安装

这里略过VScode和MinGW-W64 GCC-8.1.0的安装过程，只说一下注意事项

安装注意

在这里插入图片描述

图中另有大哥做出了解释，经过几次尝试，最终配置成功的版本是上图第二个（不过区别不大）

Visual Studio Code官网下载路径
 MinGW-W64 GCC-8.1.0官网下载路径
MinGW-W64 GCC-8.1.0的安装路径需要记清楚，后续配置要用到

配置系统环境变量

win+q
在这里插入图片描述
系统环境变量中，添加环境变量path（MinGW-W64 GCC-8.1.0的安装路径）

我的路径是：D:\vscode\MyVsTool\CEdit\MinGWIns\mingw64\bin

检查是否配置成功

cmd中输入gcc -v

VScode配置C/C++环境

下载C/C++插件
创建一个要用来运行C代码的文件夹，命名为.vscode（配置相关文件,不要省略.）
在.vscode文件夹下创建三个文件c_cpp_properties.json、launch.json、tasks.json

c_cpp_properties.json路径需要修改

这里贴上我的测试代码

C代码

#include <stdio.h>
main()
{
	printf("Hello World!\n");
}

在这里插入图片描述

C++代码（有序线性表合并）

#include<stdio.h>
#include<stdlib.h>
#include<string.h>

#define MAXSIZE 100
#define ElemType int
#define Status int

//顺序表的数据结构
typedef struct 
{
	ElemType *data;
	int length;
}SqList;


//初始化
void InitList(SqList &L)
{
	L.data = new ElemType[MAXSIZE];
	L.length = 0;
}

//打印线性表
void PrintList(SqList L) 
{
	printf("当前顺序表的所有元素：");
	for (int i = 0; i <L.length; i++)
	{
		printf("%d ", L.data[i]);
	}
	printf("\n");
}

//创建线性表
void Create(SqList &L)
{
	int n,i;
	printf("请输入要输入元素的个数：");
	scanf("%d", &n);
	if (n<0 || n>MAXSIZE) 
	{
		printf("请输入正确的个数!\n");
	}
	for (i = 0; i < n; i++) 
	{
		printf("请输入第%d个元素：",(i+1));
		scanf("%d", &(L.data[i]));
		L.length++;
	}

}


//合并二个有序线性表到C中
void MergeList(SqList &A, SqList &B, SqList &C)
{
	int i=0, j=0,k=0;
	int m = A.length;
	int n = B.length;

	while(j < n && i< m)
	{
			if (A.data[i]>B.data[j])
			{
				C.data[k] = B.data[j];
				C.length++;
				k++;
				j++;
			}
			else
			{
				C.data[k] = A.data[i];
				C.length++;
				k++;
				i++;
			}
	}
			
	while (i < m)	//B已到达表尾，依次将A的剩余元素插人C的最后
	{
		C.data[k] = A.data[i];
		C.length++;
		k++;
		i++;
	}
	while (j < n)	//A已到达表尾，依次将B的剩余元素插人C的最后
	{
		C.data[k] = B.data[j];
		C.length++;
		k++;
		j++;
	}


}

int main()
{
	SqList A, B,C;
	//初始化
	InitList(A);
	InitList(B);
	InitList(C);
	//创建
	printf("请输入集合A的元素：\n");
	Create(A);
	printf("请输入集合B的元素：\n");
	Create(B);

	//合并A和B集合到A中
	MergeList(A, B, C);
	PrintList(C);
