question regarding to C#include #include #include int main() { int n = 3; double *tptr = malloc(n*sizeof(double)); if (tptr != NULL) free(tptr); return 0; } got such error: error C2440: 'initializing' : cannot convert from 'void *' to 'double *' Conversion from 'void*' to pointer to non-'void' requires an explicit cast what's wrong with it? Thanks

那么请问VC的default可不可以改成C?谢谢

suggest use: double *tptr = new double[n]if you use malloc(), you must tell which kind of type you want to convert. suggest use new and delete in C++: double *tptr = new double[n]; ... delete tptr;
