Original: https://snap.berkeley.edu/snapsource/snap.html#present:Username=dan%20garcia&ProjectName=CSPrinciplesReferenceSheetSnap!Assignment, Display, and InputText: a ← expression
Evaluates expression and then assigns a copy of the result to the variable a.Text: DISPLAY(expression)
Displays the value of expression, followed by a space.Text: INPUT()
Accepts a value from the user and returns the input value.Arithmetic Operators and Numeric ProceduresText and Block: a+b, a-b, a*b, a/b
The arithmetic operators +, -, *, and / are used to perform arithmetic on a and b.
For example, 17 / 5 evaluates to 3.4.
The order of operations used in mathematics applies when evaluating expressions.Text: a MOD b
Evaluates to the remainder when a is divided by b. Assume that a is an integer greater than or equal to 0 and b is an integer greater than 0.
For example, 17 MOD 5 evaluates to 2.
The MOD operator has the same precedence as the * and / operators.Text: RANDOM(a,b)
Generates and returns a random integer from a to b, including a and b. Each result is equally likely to occur.
For example, RANDOM(1, 3) could return 1, 2, or 3.Relational and Boolean OperatorsText and Block: a=b ,a≠b, a>b, a<b, a≥b, a≤b
The relational operators = , ≠, >, <, ≥, and ≤ are used to test the relationship between two variables, expressions, or values. A comparison using relational operators evaluates to a Boolean value.
For example, a = b evaluates to true if a and b are equal; otherwise it evaluates to false.Text: NOT condition
Evaluates to true if condition is false; otherwise evaluates to false.Text:
condition1 AND condition2
Evaluates to true if both condition1 and condition2 are true; otherwise evaluates to false.Text: condition1 OR condition2
Evaluates to true if condition1 is true or if condition2 is true or if both condition1 and condition2 are true; otherwise evaluates to false.SelectionText:
IF(condition)
{
<block of statements>
}
The code in block of statements is executed if the Boolean expression condition evaluates to true; no action is taken if condition evaluates to false.Text:
IF(condition)
{
<first block of statements>
}
ELSE
{
<second block of statements>
}
The code in first block of statements is executed if the Boolean expression condition evaluates to true; otherwise the code in second block of statements is executed.IterationText:
REPEAT n TIMES
{
<block of statements>
}
The code in block of statements is executed n times.Text:
REPEAT UNTIL(condition)
{
<block of statements>
}
The code in block of statements is repeated until the Boolean expression condition evaluates to true.List OperationsText: aList ← [value1, value2, value3, ...]
Creates a new list that contains the values value1, value2, value3, and ... at indices 1, 2, 3, and ... respectively and assigns it to aList.Text: aList ← []
Creates an empty list and assigns it to aList.Text: aList ← bList
Assigns a copy of the list bList to the list aList.
For example, if bList contains [20, 40, 60], then aList will also contain [20, 40, 60] after the assignment.
Text: aList[i]
Accesses the element of aList at index i. The first element of aList is at index 1 and is accessed using the notation
aList[1].
Text: x ← aList[i]
Assigns the value of aList[i] to the variable x.Text: aList[i] ← x
Assigns the value of x to aList[i]Text: aList[i] ← aList[j]
Assigns the value of aList[j] to aList[i].Text: INSERT(aList, i, value)
Any values in aList at indices greater than or equal to i are shifted one position to the right. The length of the list is increased by 1, and value is placed at index i in aList..Text:APPEND aList, value
The length of aList is increased by 1, and value is placed at the end of aList.Text: REMOVE(aList, i)
Removes the item at index i in aList and shifts to the left any values at indices greater than i, The length of aList is decreased by 1.Text: LENGTH(aList)
Evaluates to the number of elements in aList.Text:
FOR EACH item IN aList
{
<block of statements>
}
The variable item is assigned the value of each element of aList sequentially, in order, from the first element to the last element. The code in block of statements is executed once for each assignment of item.Procedures and Procedure CallsProcedures are defined with the "make a block..." context menu. Right-click (on Macs control-click) on the Scripts background to get to it. There's also a "Make a block" button in the Variables tab. Procedures that return values should be a "Reporter" (or "Predicate").
Procedures that don't return values should be a "Command".Text:
PROCEDURE procName(parameter1, parameter2, ...)
{
<block of statements>
}
Defines procName as a procedure that takes zero or more arguments. The procedure contains block of statements.
The procedure procName can be called using the following notation, where arg1 is assigned to parameter1, arg2 is assigned to parameter2, etc.: procName(arg1, arg2, ...)
Text:
PROCEDURE procName(parameter1, parameter2, ...)
{
<block of statements>
RETURN(expression)
}
Defines procName as a procedure that takes zero or more arguments. The procedure contains block of statements and returns the value of expression. The RETURN statement may appear at any point inside the procedure and causes an immediate return from the procedure back to the calling statement.
The value returned by the procedure procName can be assigned to the variable result using the following notation: result ← procName(arg1, arg2, ...)
Text: RETURN(expression)
Returns the flow of control to the point where the procedure was called and returns the value of expression.Robot If the robot attempts to move to a square that is not open or is beyond the edge of the grid, the robot will stay in its current location and the program will terminate.END OF SNAP!
