Change this program to loop until it encounters a sentinel value, which is a negative number. The data begins at x3100. Use only one branch command. There will always be at least one positive integer in the list. Do not use a count controlled loop. When the program ends, R2 must contain the number of values summed and R3 must contain the sum of those values. ORIG x3000 AND R3, R3, #0 AND R2, R2, #0 ADD R2, R2, #12 BRz #5 LDR R4, R1, #0 ADD R3, R3, R4 ADD R1, R1, #1 ADD R2, R2, #-1 BRnzp #-6 .END
Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
Change this
ORIG x3000
AND R3, R3, #0
AND R2, R2, #0
ADD R2, R2, #12
BRz #5
LDR R4, R1, #0
ADD R3, R3, R4
ADD R1, R1, #1
ADD R2, R2, #-1
BRnzp #-6
.END
