Stand up Learn the name of someone you don t know Sit down

With a growth mindset, we can improve our skills through practicing. Learning happens over time, not instantly. The process of learning is uncomfortable when we re not competent yet.

Be prepared to program in class every day!

Math and programming look similar, but aren t the same

Lines of code are executed in order = is an assignment operator Programming is typo-intolerant You have to say the magic words exactly right for the spell to work!

Variables hold information Variables can change value while the program is executing Example int myRoll;

Methods are like a factory: They take input, and spit out results Example Random.Range(1,7);

+= // if ()

totalScore = 0; myRoll = Random.Range(1, 7); totalScore = totalScore + myRoll;

totalScore = 0; myRoll = Random.Range(1, 7); totalScore += myRoll;

// Player starts with a score of 0 totalScore = 0; // Roll 1d6 myRoll = Random.Range(1, 7); // Add the roll to the score totalScore += myRoll;

totalScore = 0; // Random.Range excludes the max number when // given ints, so this returns a number 1-6 myRoll = Random.Range(1, 7); totalScore += myRoll;

totalScore = 0; // Random.Range excludes the max # for ints myRoll = Random.Range(1, 7); if (myRoll > 4) { totalScore += myRoll; }

> means greater than < means less than >= means greater than or equal to <= means less than or equal to == means equal != means not equal && means AND || means OR Remember that = is an assignment operator!

How could I display the numbers 1 to 9?

How could I display the numbers 1 to 9? print ( 1 ); print ( 2 ); print ( 3 ); print ( 4 ); print ( 5 ); print ( 6 ); print ( 7 ); print ( 8 ); print ( 9 );

How could I display the numbers 1 to 99? 1 to 999?

// Count from 1 to 9 for (int i = 1; i < 10; i += 1) { print (i); } // We could also use a while() loop int i = 1; while (i < 10) { print (i); i += 1; }

// Count from 1 to 99 for (int i = 1; i < 100; i += 1) { print (i); } // We could also use a while() loop int i = 1; while (i < 100) { print (i); i += 1; }

// Count from 1 to 999 for (int i = 1; i < 1000; i += 1) { print (i); } // We could also use a while() loop int i = 1; while (i < 1000) { print (i); i += 1; }
