C/C++, How do you code for the download progress thing in the CLI? Linux

Im looking to make program with a similar feature as the Download Progress Text with the arrow going across.. Example PIC is a reference to what im talking about.

我希望使用与箭头相交的下载进度文本类似的功能制作程序。示例PIC是我正在谈论的内容的参考。

Any libraries or designs with basic functions? Thanks for any help!

The library you are looking for is ncurses. It can be found here.

您正在寻找的图书馆是ncurses。在这里能找到它。

Here is another resource I found for ncurses that may be useful to help introduce you to the library and its functionality. It's a series of Youtube tutorials -- his speaking is poor but from what I can tell (listening only to the first two videos) his examples are sufficiently well taught.

这是我为ncurses找到的另一个资源，可能有助于向您介绍库及其功能。这是一系列Youtube教程 - 他的演讲很糟糕，但从我能讲的（只听前两个视频）他的例子得到了很好的教导。

You may use boost::progress_display

你可以使用boost :: progress_display

If all you want is a progress bar for some data, you should check out pv. One way to use it is to simply pipe your data through the program. Here is a simple example below that just reads in a file using a call to pv with popen():

如果你想要的只是一些数据的进度条，你应该看看光伏。使用它的一种方法是简单地通过程序管道数据。下面是一个简单的示例，只需使用popen（）调用pv即可读取文件：

#include <stdio.h>

int main (int argc, char *argv[]) {
    char pv[1024];
    FILE *infile;
    if (argc > 1) {
        char c;
        snprintf(pv, sizeof(pv), "pv %s", argv[1]);
        infile = popen(pv, "r");
        while (fread(&c, 1, 1, infile)) {}
        pclose(infile);
    } else {
        puts("need a file name!");
    }
    return 0;
}
