C语言???

大学被迫学C。
0.没有using namespace std;
1.C的文件输入输出

#include 
#include 
#include 
int i,j,k,m,n,o,p,l,s,t;
int main()
{
    FILE *fin=fopen("test.txt","r+");
    FILE *fout=fopen("test.out","w+");
    fscanf(fin,"%d",&n);
    for (i=1;i<=n;i++) fscanf(fin,"%d",&t),s+=t;
    fprintf(fout,"%d\n",s+1);
    fclose(fin);fclose(fout);
    return 0;
}

2.codeblocks使用
如何打开一个项目
debug教程
3.vscode使用方法
看这里
不显示终端被占用

在这里插入代码片//tasks.json
