Need help with string operation

[Rafi2003]

HI,

Although it seems simple....I'm having difficulties to do this....

I'm reading with a bar code the UUT ID as follow:    "ABCDEFG    12"

The number of spaces may vary from 1 to 3.....also the second part may be of 2 or 3 characters.

I'm trying to get the last part into a buffer.  I'm having difficulties due to the fact that the number of spaces is not equal.

Can you help?

Thanks

Use FindPattern to search for a single space starting from right: this will give you the index of the number after the spaces. Next strcpy (string + index, new_variable) and that's all.

Hi,

I haven't tested this, but it should work.

char barCode[MAX_LEN], barCodeEnd[MAX_LEN];
int i;

strcpy(barCode, "ABCDEFG 12");

for( i = strlen( barCode ) ; 0 < i && isdigit( barCode[i] ) ; i-- );
++i;

if( i < strlen(barCode) && isdigit( barCode[i] ){
strcpy(barCodeEnd, &barCode[i]);
}
else{
strcpy(barCodeEnd, "No digits");
}

Type softly, read gently.

Another possibility, supposing the first part is always and only alphabetic and the second always and only numeric, could be to use

Fmt (string, "%s[t#]%d", string1, number);

the [t#] modifier instructs the Scan function to terminate scanning the source string on the first numeric character. Scan and Fmt functions in the Formatting and I/O are powerful functions and are well documented in the online help.

Or you could just try:

 char Barcode[50] = {"ABCDEFG  \t123"};
 char  String[50];
 int  Number;
 
 sscanf(Barcode, "%s%d", String, &Number);

This doesn't care how many spaces or tabs are in between the alpha numeric field and the numeric field
