You could put this string into a char array and then scan through each char. The equal sign precedes the info you want written out to a file. So when the letter you're looking at is an equal sign, you know that you need to write out the next several char's, until you reach the colon, which marks the end of the field.

What part are you stuck on? Show me your code to handle this, and explain your specific troubles, please.

save it as one.c
and compile
gcc one.c -o one `pkg-config gtk+-2.0 --cflags --libs`

i used some gtk functions here.

i know now you are clear about this

please help me

thank you in advance

You're already using strtok() but unfortunately only with the '\n' delimiter. Instead, why don't you use it a little more advanced:

1. split your input using the delimiter ':', this will give you a sequence of "option=value" items (as long as neither option nor value contains the ':').

2. split your sequence of "option=value" with the delimiter '=' which will give you the 2 items option and value

3. print the value corresponding to your options.

The whole thing shouldn't take more than .... 10 lines max.

Wow! That's a boatload of code!! :)

I don't mean to be unkind, but it seems to be suffering from the all too familiar "Rube Goldberg" effect.


Let's look at the problem again:

Quote:

---

ID=123:one=a:[email protected]:three=789:four=:five= 123 ID=123:one=aa:[email protected]:three=:four=1111111 111:five=
:/

i would like to truncate this write in a file (file.txt) as

---

Code:

---

//begin
a
[email protected]
789

123
//begin
aa
[email protected]

11111111
//begin

---

What I was thinking of was just two while loops:

Code:

---

While (there are more char's to be looked at in the string)  {
  ch = next char.
  if (ch == '=')
        while (1)  { 
              (ch2 = next char in the string
              if ((ch2 != ':') && (ch2 != NULL))
                  write ch2 to the file;
              else
                  break;
        }
}

---

The loops could be for loops working from 0 to strlen(string) - 1.

I'm sure the half-code above is incomplete, but I hope it conveys my thoughts on this. I don't think you want "one" "two" --> "seven", etc. Make it something generic so it will handle any number of entries, and at the same time, make it as simple, small and clear as possible.

no am unable to write the code in 10 lines

can anybudy rewrite the code please

thank you in advance

No, I couldn't write the program, I don't use that compiler and don't have those header files. More importantly, you get better at programming if you practice - like anything else.

I know it's time consuming and it can be frustrating, but I believe you have two ways of doing this program, laid out before you.

thank you for boosting.

i succeeded.
but still having a problem
it will not printing
fist "five"(i.e. 123),and it is printing remaining "five".

whats the problem.

can you please help me .

thank you in advance

Could it have anything to do with the odd numbering in the code?

Code:

---

if(strstr(ref[j],"one")!=NULL)
                {
                char **split1;
                split1=g_strsplit(ref[j],"=",2);
                one=split1[1];
                printf("%s\n",split1[1]);
               
                }
                else if(strstr(ref[j],"two")!=NULL)
                {
                char **split2;
                split2=g_strsplit(ref[j],"=",2);
                printf("%s\n",split2[1]);
                two=split2[1];
               
                }
                else if (strstr(ref[j],"three")!=NULL)
                {
                char **split5;
                split5=g_strsplit(ref[j],"=",2);
                printf("%s\n",split5[1]);
                three=split5[1];
                } 
                else if(strstr(ref[j],"four")!=NULL)
                {
                char **split4;
                split4=g_strsplit(ref[j],"=",2);
                printf("%s\n",split4[1]);
                four=split4[1];
                }
                else if(strstr(ref[j],"five")!=NULL)
                {
                char **split3;
                split3=g_strsplit(ref[j],"=",2);
                printf("%s\n",split3[1]);
                five=split3[1];
                }
                else {}
             
              }

I can't run your program, so you'll have to settle for my idea's on this, only.

Adak

sorry.
i forgot some code.
actually this is the response

Code:

---

char *response="LIST=SUCCESS:ID=123:one=a:[email protected]:three=:four=456:five=666\nID=123:one=aa:[email protected]:three=22222222:four=:five=0000000000\n:/";

---

there is an extra ":" in first line so,
the first "five"(i.e. 666) is not printing.

can you please help me in this way

thank you in advance

Above the loop that has you checking each char, put a while loop into your code. Conceptually, something like this:

Code:

---

/* n is an int, and you may need to use the ASCII value of '=', instead of '=' (which is 61) */
while ((n = getchar()) != '=');  /* gets char's and converts to int's until it reaches an equal sign. */

---

Note the double (( before the n, and a single extra ) after the getchar, as well as the ; at the end of the compact while statement.

This is not the best answer to your needs, but it may be ONE answer, in this case.

/* n is an int, and you may need to use the ASCII value of '=', instead of '=' (which is 61) */

No, you never have to. In C, character literals are actually int values anyway, but even in C++, where they are chars, you don't have to, because it's casted implicitly.
