c - 添加一个 int 到 char* 的中间(在 C 中)

Question

想知道怎么可能在 char* 中间有一个 int，像这样:

char * winning_message =
"Congratulations, you have finished the game with a score of " + INT_HERE +
"                 Press any key to exit...                   ";

Answer 1

也许您正在寻找这样的东西？

char buf[256];  // make sure this is big enough to hold your entire string!
sprintf(buf, "Congratulations, you have finished the game with a score of %i\nPress any key to exit...", INT_HERE);

请注意，如果您的字符串最终比 sizeof(buf) 长，则上述内容是不安全的，sprintf() 将写入超过它的末尾并破坏您的堆栈。为避免这种风险，您可以改为调用 snprintf():

char buf[256];  // make sure this is big enough to hold your entire string!
snprintf(buf, sizeof(buf), "Congratulations, you have finished the game with a score of %i\nPress any key to exit...", INT_HERE);

...唯一的缺点是 snprintf() 可能不适用于所有操作系统。
