Need help with computer science question
![Suppose we have the following C function:
long average (long a 0) { // finds the average (arithmetic mean of an array of 8 elements
long sum = 0;
for (int i = 0;
sum += a[i):
i < 8;
i++) (
// loop through all elements
}
return sum/8; // find the average by dividing by the number of elements (8).
}
In the assembly implementation of the function below, fill in the three missing jump instructions so that it matches the code above:
average:
xorg trax, trax
xorg trcx, trcx
# sum = 0
* i = 0

labell:
# sum = sum + a[i]
# i = i+1

Expert Solution
Step 1
In computer programming, assembly language, sometimes abbreviated asm, is any low-level
programming language in which there is a very strong correspondence between the instructions
in the language and the architecture's machine code instructions.
