How to store 3 different types of data in one array

I need to store 3 linked bits of data in c. My original thought was a 3 dimensional array but that won't work as all 3 data types are different. The top level needs to be a char. The second level needs to be a date/time so a integer. The third level is a temperature reading so needs to be a float.

Is the correct way to do this an array of pointers pointing to an array of pointers pointing to a array of floats? If so how would that be written in C?
