在结构的“数组”中访问和分配结构的每个部分中的值？

Question

So I have an assignment to allocate enough memory to store a set of structs with different values in them. I am only allowed to call malloc once.

A have a struct that looks like this:

typedef struct ObjectTag Object;
struct ObjectTag
{
    char *stringA[20];
    char *stringB[30];
    char *stringC[5];
    unsigned short num;
};

For my malloc call I am doing

Object *myObjArray;
myObjArray= (Object*)malloc(numObjects * sizeof(Object));

I am trying to get information from an infile to place into my structs. Thus I am doing

fscanf(inFile, " %s", (*Object)[i].stringA);
fscanf(inFile, " %s", (*Object)[i].stringB);
fscanf(inFile, " %s", (*Object)[i].stringC);
fscanf(inFile, " %hu", (*Object)[i].num);

and so on in a loop.

But when I try to compile I get this error

format '%s' expects argument of type 'char *', but argument 3 has type 'char **'

and also this for the last one

format '%hu' expects argument of type 'short unsigned int *', but argument 3 has type 'int'

I have no idea what I'm doing wrong.

Notes that may be relevant:

• The infile has an expected format to it
• I have counted how many structs I needed as noted by the numObjects in the malloc call

char *stringA[20] is NOT a string of 20 (or 19) characters. It is an array of 20 strings of unspecified length . Are you sure this is what you want?
