How to parse a file and store few strings in an array

I wrote it over breakfast; what's missing?

Nothing is missing, however an underscore is not an hyphen. --Carlo The Nitpick.

That code was a beauty again .... :-D Actually... the final file after strtok() looks like the one below... :|

Token: DCLGEN
Token: LIBRARY
Token: ACTION
Token: LANGUAGE
Token: NAMES
Token: QUOTE
Token: COLSUFFIX
Token: IS
Token: EXEC
Token: POLICY_NO
Token: REG_NO
Token: EFFECTIVE_DATE
Token: EXPIRY_DATE
Token: CAN_EFF_DATE
Token: CAN_PRO_DATE
Token: RETURN_PREMIUM
Token: CAN_PROCESSED
Token: END-EXEC
Token: COBOL
Token: DCLCANCL
Token: POLICY_NO
Token: CN-POLICY-NO //I need this string too in diff array name tableRow[6][10]
Token: REG_NO
Token: CN-REG-NO //I need this string too in diff array name tableRow[6][10]
Token: EFFECTIVE_DATE
Token: CN-EFFECTIVE-DATE //I need this string too in diff array name tableRow[6][10]
Token: EXPIRY_DATE
Token: CN-EXPIRY-DATE //I need this string too in diff array name tableRow[6][10]
Token: CAN_EFF_DATE
Token: CN-CAN-EFF-DATE //I need this string too in diff array name tableRow[6][10]
Token: CAN_PRO_DATE
Token: CN-CAN-PRO-DATE //I need this string too in diff array name tableRow[6][10]
Token: RETURN_PREMIUM
Token: CN-RETURN-PREMIUM //I need this string too in diff array name tableRow[6][10]
Token: CAN_PROCESSED
Token: CN-CAN-PROCESSED //I need this string too in diff array name tableRow[6][10]
Token: THE

Your code cleverly extracted the strings within EXEC and END-EXEC which I stored in

char tableCol[6][10]

But now I am finding it really difficult to store the strings which are immediatedly followed by the "tabCol" string from the file... :( ie CN-POLICY-NO, CN-REG-NO, CN-EFFECTIVE-DATE, CN-EXPIRY-DATE, CN-CAN-EFF-DATE, CN-CAN-PRO-DATE, CN-RETURN-PREMIUM & CN-CAN-PROCESSED which are to be stored in

char tableRow[6][10]

Apologies ...:( Thanks a ton, Faez

Since they all begin with "CN-", you could add a test:

if (strncmp(tok, "CN-", 3) == 0)
printf ...

Alternatively you have to test for each one individually.

Which won't be large enough.

No no... It ain't always preceeded with "CN-" string ... The strings which needs to be stored in TabRow array are followed by the second occurrence of each tableCol values... Initially I also thought of using strcat () and append CN- to the tabCol values... But den I realized that it was for this file only... Other files are completely different. Regards, Faez

If you don't have a common character identifier to select your strings then there is little that can be done. And from what you say you will have different rules for different files so it's difficult to suggest any other options.

Finally I have come up witha Not-so-good code... But it works.. :) I created another similar situation to parse from END-EXEC to End of File as below...

if (k == 0)
{
if (strcmp(tok, "END-EXEC") == 0)
k = 1;
}
else
{
if (strcmp(tok, "THE") == 0)
{
k = 0;
}
else
{
strcpy(tabRow[m],tok);m++;
fprintf(fp3,"Token: %s\n", tok);

}
}
}
// Out of all the loops and condition now....

j=0,n=0;
for(j=0;j<=m;j++)
{
	if(strcmp(tabCol\[n\],tabRow\[j\])==0)
	{
		k=j;
		strcpy(tabRow\[n\],tabRow\[k+1\]);
		n++;
	}
	else ;


}
for(k=0;k

It wud be nice to get ur comments on this... :-D

Thanks,

Difficult to say really. Assuming it does what you want then that's fine, but I don't see any checks for the specific strings after the "END-EXEC" that you wish to save. Or perhaps that is what the line

if(strcmp(tabCol[n],tabRow[j])==0)

is doing.
