code 1

Modify the code according to the lecture in a way that it stops once the variable is close to

zero.

Code 2

when the variable is close to zero print the message in the serial monitor and stop

decrementing.

Code 3

Use addition operator to combine the values of text1 and text2

Make the program find the index of character m in both strings text2 and text3.

Change the data types String to char to try array of characters to assign text and

messages to the variables text1,text2 and text3

Replace text#.length() in the original code with strlen(text#)

Replace text#.concat(text#) in the original code with strcpy(text#,text#)

Using strcmp function, compare text3 with text1+text2.
