Hello
Im trying to send values to PC in the format
PxxxxRyyyyTzzzz
where xxxx, yyyy, zzzz should b 4 digit no.s. and P R Z are ASCII characters
i use
serial.print("P");
serial.print(p);
serial.print("R");
serial.print(r);
serial.print("T");
serial.print(t);
where integers p, r and t correspond to xxxx,yyyy,zzzz repectively
no. of digits of p, r , t vary from 1 to 4
how to stuff is with zeros and print viz. if p is 54, it must be printed as 0054 ?
is it possible print such a format above using single serial.print statement?
please help out
Thanks in advance

No, it is not.
You can use sprintf to format a string, and then print that string.
int x = 14;
int y = 126;
int z = 1007;
char tbs[16];
sprintf(tbs, "P%4dR%4dT%4d", x, y, z);
This will result in tbs containing:
P 14R 126T1007
which you can then send using:
Serial.print(tbs);

i get error: sprintf is not declared in this scope

Add this to the sketch:
#include <stdio.h> // for function sprintf

By the way, if you want to pad the number with zeros instead of spaces, change the %4d to %04d in your sprintf format.
