如何使用sprintf附加字符串? [英] How to append strings using sprintf?

问题描述

我在使用 sprintf 时遇到了一个严重的问题.

I am facing a serious issue with sprintf.

假设我的代码片段是:

sprintf(Buffer,"Hello World");
sprintf(Buffer,"Good Morning");
sprintf(Buffer,"Good Afternoon");
.
.
.

几百次冲刺......

Some hundred sprints....

如果我喜欢这个，它就会被覆盖.

If I do like this, it's getting overwritten.

如何避免使用 sprintf 覆盖?如果我在最后给出 printf，我想查看所有行.

How can I avoid overwriting using sprintf? If I give a printf at the end I want to see all the lines.

推荐答案

您需要:

sprintf(Buffer,"Hello World");
sprintf(Buffer + strlen(Buffer),"Good Morning");
sprintf(Buffer + strlen(Buffer),"Good Afternoon");

当然，您的缓冲区需要足够大.

and of course you need your buffer to be big enough.
