c - 如何将整数数组内容复制到字符指针？

Question

我有一个字符指针，char *buf;我有一个整数数组，int console_buffer[256];我需要将 console_buffer 内容复制到字符 buf。我该怎么做呢？ buf 和 console_buffer 是不同结构的一部分。

Answer 1

根据您的评论，

buf = malloc(256); // 257 if console_buffer may be full without EOF
/* if you want to allocate just as much space as needed, locate the EOF in console_buffer first */
for(int i = 0; i < 256 && console_buffer[i] != -1; ++i){
    buf[i] = (char)console_buffer[i];
}
