Description
Programming Question:
Write a program in MIPS assembly language that asks the users to enter a value for array size “n” and fill up the array with n integers. Then reverse the array and print it on the screen. You are required to do the following in your program:
- Create up to 80 bytes of space in your program
- “n”, the array size, should be greater than zero and less than 20
- Each element of the array should be positive and divisible by 3
- Array should be reversed within itself. i.e. you must not create another array to place the elements in reverse order
You need to use following functions:
int main( )
{
Begin: arraysize= readNum()
Ok=verifySize(arraySize)
if (ok==1)
creatArray(array-size)
else
Go to Begin
printArray(arraySize)
reverseArray(arraySize)
printArray (arraySize)
}
// ————————————————————
int readNum()
{
input an integer
return the integer to main program
}
// ————————————————————
int versifySize( int arraySize)
{
if (0<arraySize< 20)
return 1
else
return 0
}
// ————————————————————
void createArray(int arraySize)
{
counter = 0
making_array: arrayEntry = readNum()
ok = checkNumPositive(arrayEntry)
if (ok == 1)
validNum = divisibleBy3(arrayEntry)
if (validNum==1)
insert arrayEntry into the array
counter = counter + 1
else
go to making_array
else
go to making_array
if (counter < arraySize)
go to making_array
}
// ————————————————————
void reverseArray(int arraySize)
{
head = first index of the array
tail = last index of the array
swap: if (head <=tail)
{
swap the content of head and tail (array[head] and array[tail] with each other
increment the head value by one word
decrement tail by one word
go to swap
}
}
// ————————————————————
void printArray( int arraySize)
{
..

}
// ————————————————————
int divisibleBy3(int arryEntry)
{
…
…
}
// ————————————————————
int checkNumPositive(int arrayEntry)
{…
}
