contributed by < Hande1004 > 第一周測驗 1 在這題當中，主要要達成的是完成 list_insert_before() 這個函式，這是能夠把所要插入的 item 插入佇列當中的函式。 以下圖片為list_insert_before()詳細功能介紹: image { list_item_t **p; for (p = AAAA; *p != BBBB; p = CCCC)

Quiz1 problem C c code for function fabsf static inline float fabsf(float x) { uint32_t i = *(uint32_t *)&x; // Read the bits of the float into an integer i &= 0x7FFFFFFF; // Clear the sign bit to get the absolute value x = *(float *)&i; // Write the modified bits back into the float return x; } :::danger Don't paste code snip without comprehensive discussions.
