I am currently learning pointers. I am following a book (Says Teach Yourself "Arduino Programming") in which there is an exemple about pointer and array.
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
char string1[] = "This is my test string";
char string2[]="This is another string test";
char *ptr2 = string2;
char *ptr1 = string1;
while (*ptr1 != '\0') { // not "\0"
*prt2 = *prt1;
ptr1++;
prt2++;
}
Serial.println(string1);
Serial.println(string2);
}
void loop() {
// put your main code here, to run repeatedly:
}
I get an error "ptr2 was not declare in this scope."
I don't know what is wrong...
That for your help.
