Arduino split data into 5 strings

[taeminshin0708]

So basically I want to make a void function that splits the parameter value into 5 global variables. So if I put "05:13:2021:11:06", the numbers should be divided and saved separately in global Strings called hour, minute, year, month, and day.

void loop() {
     splitData("05:13:2021:11:06");
     Serial.println(hour + ":" + minute + ", " + year + "/" + month + "/" + day);
}

void splitData(String string) {
     . . .
}

this should print out 05:13, 2021/11/06

can anyone give me some examples?

consider following just posted in another thread
add a parallel array of ints using atoi() of the tokens

char s [80];

#define MaxTok  10
char *toks [MaxTok];

// -----------------------------------------------------------------------------
int
tokenize (
    char       *s,
    const char *sep )
{
    unsigned n;
    toks [0] = strtok (s, sep);
    for (n = 1; (toks [n] = strtok (NULL, sep)); n++)
        ;

    return n;
}

// -----------------------------------------------------------------------------
void dispToks (
    char * toks [])
{
    for (unsigned n = 0; toks [n]; n++)
        Serial.println (toks [n]);
}

// -----------------------------------------------------------------------------
void loop ()
{
    if (Serial.available ())  {
        int n = Serial. readBytesUntil ('\n', s, sizeof(s));
        s [n] = 0;      // terminate string

        tokenize (s, ",");
        dispToks (toks);
    }
}

// -----------------------------------------------------------------------------
void setup ()
{
    Serial.begin (9600);
}

String hour, minute, year, month, day;

void splitData(String string)
{
  hour = string.substring(0, 2);
  minute = string.substring(3, 5);
  year = string.substring(6, 10);
  month = string.substring(11, 13);
  day = string.substring(14);
}

void setup()
{
  Serial.begin(115200);
  delay(200);
  
  splitData("05:13:2021:11:06");
  
  Serial.println(hour + ":" + minute + ", " + year + "/" + month + "/" + day);
}

void loop() {}

Simple is the best. Why did I forget about that? That's actually perfect because the length will always stay constant. Thanks
