thanks for ur concern

i've figured out my problem and finished counting

thanks a lot everyone :)

my problem now is that i don't know what's wrong about my adding node part T_T;

else
{
current = current->next;
}


my current pointer in here doesn't seem to move anywhere but staying at the start.
can...

why does i assign current to start??
i'm confused now = =a

it's said sth like incompatible type of pointers

but i think i've figured out my problem in the structure, it should be

typedef struct node
{
char alpha;
int freq;
struct node*...

I have move the current thing in here, and the program doesn't crash anymore :))

if(start == NULL)
{
printf("test1\n");
start =...

i don't really understand what you mean ??? = =

but i try taking out the allocate thing of current and it's still crashed...

My current code is now

#include <stdio.h>
#include <ctype.h>

typedef struct node
{
char alpha;
int freq;
struct node* next;

so if i also want to count the frequency of the space then i should use the fgets one
because the fscanf doesn't read space, right?

May i ask a bit more,
what is the difference between these two
>while(fgets(buffer,127,pInfile)!=NULL)
>while ( fscanf( pInfile, "%s" , buffer ) != EOF )
or are they the same?

Thanks for helping !
This clear my confusion :)

the end doesn't include space bar right?

while(fgets(buffer,127,pInfile)!=NULL)
{
for(i = 0; buffer[i]; ++i)
{
buffer[i] = tolower(buffer[i]);
printf("%c",buffer[i]);
...

Thanks a lot :)

This program suppose to count the string length that are A-Z,a-z, and 0-9 using recursion but it counts everything, why??


#include <stdio.h>

int count(char string[])
{
int i = 0;

...

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

#include "structure.h"
#include "valid.h"

int checkCode(char* codeString,DATA_T* pResult)
{

This is an unfinished file name immigration.c

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

#include "structure.h"
#include "modifyImmigration.h"

int main(int argc,char*...

Thanks a lot ^^

This is a file name valid.c


#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#include "valid.h"
#include "structure.h"

Why when i type "none" for drink type, it doesn't print BILL.
Here is the code.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

#define MAX 30
int main()

When compile, the red line is
error, invalid lvalue in assignment
How to fix this?


#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX 30

Sorry to ask a lot, because i'm very new to c programming
can you explain,
1. what is while(1)?
2. why do you use
while(drink type length > 0); to loop?

I mean it already loop until None already
but I also want to check if the user doesn't type anything, the program should ask again
and if the user type in sth but it's not None, the program should...

i see...
is there a way to fix this?
the program want to ask the type of drink until None
but if the user type nothing, i want it to ask again.

i mean the small loop of strlen
eventhough i type in sth, it still loops
