Question

Can anyone help me with my C program? [error: expected ‘)’ before ‘*’ token]

Answer 1

I declared my structures using typedef:

typedef struct {
char OrigCurr[4];
char WantCurr[4];
float ExRate;
} STRUCTTYPE_Rates;

typedef struct {
char User[31];
char Pass[31];
char Role[14];
} STRUCTTYPE_Users;

STRUCTTYPE_Rates STRUCT_Rates[100];
STRUCTTYPE_Users STRUCT_Users[100];

I'm trying to pass the parameter by pointer:

int TXTDATA_Read_Rates(STRUCTTYPE_Rates* STRUCT_Rates, FILE *STREAM_Rates) {
//blahblah
}

int TXTDATA_Read_Users(STRUCTTYPE_Users* STRUCT_Users, FILE *STREAM_Users) {
//blahblah
}

Now when I compile, i get the following error message, for both lines above:

error: expected ‘)’ before ‘*’ token

What am I doing wrong?

Answer 2

typedef struct {
char User[31];
char Pass[31];
char Role[14];
} STRUCTTYPE_Users;

modify to

typedef struct _STRUCTYPE_Users {
char User[31];
char Pass[31];
char Role[14];
} STRUCTTYPE_Users;

now it should work...and also modify other struct declaration too

Answer 3

How come changing 'struct' to 'struct _STRUCTTYPE_Users' will solve the problem?

Answer 4

struct must have a name defined.....but no name is provided....

Answer 5

try it and tell me if the error still persist or vanishes

Answer 6

Error still persists.

Answer 7

o i got it...mhy fault..

STRUCTTYPE_Rates STRUCT_Rates[100]; // ok
STRUCTTYPE_Users STRUCT_Users[100]; // ok


int TXTDATA_Read_Rates(STRUCTTYPE_Rates* STRUCT_Rates, FILE *STREAM_Rates) // change the argument variable names....they are already declared global variables...cannot reuse the names{
//blahblah
}

int TXTDATA_Read_Users(STRUCTTYPE_Users* STRUCT_Users, FILE *STREAM_Users) // same here {
//blahblah
}

change it

Answer 8

then tell me

Answer 9

Error still persists. I changed it to :

int TXTDATA_Read_Rates(DATATYPE_Rates a, FILE *b, int *c) {

Answer 10

BTW I changed STRUCTTYPE to DATATYPE.

Answer 11

attach the whole code....let me run and c
wat happens

Answer 12

Hold on. Let's do it one at a time. My lesser problem is the pass integer by reference one, so I'm uploading my .c file where I declared the structures as global. In this way all we have to debug first is the passing integer by reference issue.

Answer 13

After fixing this one, I'm going to put the structures inside the main function and put the necessary parameters so that we can debug that problem next.

Answer 14

Umm I forgot to delete the expletives in my code (lol). Just ignore it; I was using them to test if the functions were getting called correctly.

Answer 15

i just get the following warnings:::

Answer 16

I get these:

file.c: In function ‘TXTDATA_Read_Rates’:
file.c:93: warning: assignment makes pointer from integer without a cast
file.c:95: warning: return makes integer from pointer without a cast
file.c: In function ‘TXTDATA_Read_Users’:
file.c:116: warning: assignment makes pointer from integer without a cast
file.c:118: warning: return makes integer from pointer without a cast

Answer 17

ok...
got rid of all the warnings and errors...
check it

Answer 18

Thanks, that works now. May I ask why you put 2 asterisks in FILE **STREAM_Rates?

Answer 19

Also I'm uploading the .c file again. This time we're debugging for the struct errors.

Notice that I changed the parameters in function int TXTDATA_Read_Rates and it still gave me these errors:

test.c:74: error: expected ‘)’ before ‘a’
test.c:99: error: expected ‘)’ before ‘STRUCT_Users’
test.c:153: error: expected ‘)’ before ‘STRUCT_Users’
test.c:175: error: expected ‘)’ before ‘STRUCT_Users’
test.c:210: error: expected ‘)’ before ‘STRUCT_Users’
