问题 I've got a int that I want to convert to 3 ints for the index of a 3d array, here's an example of what I'm on about. byte[,,] array = new byte[XSize, YSize, ZSize]; int i = 0; //other code array[#,#,#] = cur; //other code I don't know how to get the correct numbers for the #,#,# from just i. 回答1: Supposing you want to iterate through Z, then Y, and then X. . . int zDirection = i % zLength; int yDirection = (i / zLength) % yLength; int xDirection = i / (yLength * zLength); 回答2: You have to

问题 I have an input function like : int func(char* s[]) { // return number of rows in the character array s } where the char array s is provided randomly as for eg: {"sdadd", "dsdsd", "dsffsf", "ffsffsf"}. Here output should be 4 for above example. 回答1: Passing string arrays requires more information... This is similar to the input you would find in say a call to int main(int argc, char *argv[]) . The exception is that when main() is called, it reads the command line and provides count

问题 I use ctypes to access a file reading C function in python. As the read data is huge and unknown in size I use **float in C . int read_file(const char *file,int *n_,int *m_,float **data_) {...} The functions mallocs an 2d array, called data , of the appropriate size, here n and m , and copies the values to the referenced ones. See following snippet: *data_ = data; *n_ = n; *m_ = m; I access this function with the following python code: p_data=POINTER(c_float) n=c_int(0) m=c_int(0) filename=
