If I have a program where :
char *X= "Fri, 27 Feb 1998" ;

How would I access "Fri", "27", "Feb" "1998" individually ?
Given the fact I don't  know the number of blank spaces
between them ???

Any ideas ..
Any help will be appreciated.

Thanks

You can use the strtok function and check for the length of the returned strings.

char *X="Fri, 27 Feb 1998";
char *wd = strtok(X," ,");
char *md = strtok(0," ,");
char *mon = strtok(0," ,");
char *year = strtok(0," ,");
printf("%s, %d %s %d\n",wd,atoi(md),mon,atoi(year));

Well, actually strtok() serves as a tokenizer; a scan seems more appropriate here.

char *X="Fri, 27 Feb 1998";
char *wd = (char *)malloc(strlen(X));
char *mon = (char *)malloc(strlen(X));
int md,year;
sscanf(X,"%[^, ]%*c%d %s %d",wd,&md,mon,&year);

:)

But... shouldn't be:

char *wd = malloc(strlen(X) + 1);

(also, the typecast is discouraged if you are writing - and compiling - ANSI-C code, because fools the compiler; it is needed by C++)

Sorry. In my haste I neglected to #include <stdlib.h> or <malloc.h> to declare malloc,
and casting was the easiest way to get rid of the warnings.

I thought of strlen(X)+1 too, but figured as long as at least one other field matched...

Maybe strdup(X) would have been simpler.

you may use strtok() or you may write a small fnc as shown below.(please include stdio.h and malloc.h)
char *[] FormatDate(char *SrcDate){ static char *FormattedStrings[4];int i=j=k=len=0;
for(;SrcDate[i] && j<4;j++,k=i,len=0)
{ for(;SrcDate[i] && SrcDate[i]!=' ' && SrcDate[i]!=',';i++,len++);
FormattedStrings[j]=(char*)malloc(len+1);
strncpy(FormattedStrings[j],&SrcDate[k],len);}}
return FormattedStrings;}
/* the required format is stored in strings in a DD  cahr array */
