1. i=(int)log((double)n)/log((double)2)+1;强制类型转换格式:(type)data 而不是:type(data) 如:(double)n, 非double(n)\ 2. x是一个临时变量,当离开FindTree后,其内容就是不可预测的了,所以返回其地址对调用者没有意义。3. C2198错误可能是由1引起的。

1、C语言中,有两个log函数,分别为log10和log函数,具体用法如下:2、函数名: log10 功 能: 对数函数log,以10为底 用 法: double log10(double x);程序示例:include <math.h> include <stdio.h>int main(void){ double result;double x = 800.6872;result = log10(x);printf("The...
(G/R), i.e. matUPD/patUPD ratio of ~1 and thus equal growth/proliferation potential of RGPs regardless of the UPD status (Fig.1d–f). These results indicate thatCdkn1chas no prominent cell-autonomous role in cell-cycle regulation of proliferating cortical RGPs. To directly test this ...

函数级的实现:应当作为log库存在,每个需要log的模块都链接它而非源码包含它;但对于不怎么让用依赖库的场景下,把log的实现包含在各个模块中,每个模块能快速开发;隐患是各个模块编译后可能产生同名符号,集成多个模块时触发链接问题,并且由于不同编译器对应的链接器的链接策略不同,导致PC和设备结果不一致。
