Converts string1, a character string, to an unsigned long int value. The strtoul() function decomposes the entire string into three parts: A sequence of characters, which in the current locale are defined as white-space characters. This part may be empty. A sequence of characters interpreted...
str: An array of characters (a string) containing the input" 123". ptr: A character pointer that will be used to track the parsing progress bystrtoumax(). value: An unsigned integer variable to store the converted value. We use thestrtoumax()function to perform the conversion: ...

ToUInt32(String, IFormatProvider) 使用指定的区域性特定格式设置信息,将数字的指定字符串表示形式转换为等效的 32 位无符号整数。 ToUInt32(String, Int32) 将指定基数的数字的字符串表示形式转换为等效的 32 位无符号整数。 ToUInt32(Single) 将指定的单精度浮点数的值转换为等效的 32 位无符号整数。
calloc(256,sizeof(unsigned char));函数返回一个void*类型；需要强制转换 unsigned char* lut=(unsigned char*)calloc(256,sizeof(unsigned char));注意需要加头文件：#include<malloc.h> 望采纳谢谢~unsigned

You convert -5.0 to unsigned char and get 251. You convert -5.0 to unsigned int and get 65531. Regarding option A and B, it is absolutely not clear what doesn't work. You had to specify what values do you supply to your routines, what do you get and ...
