Question

The purpose of the program is to read in a list of 10 integers and then print them out. There are 4 functions in the program: 2 of which you are to complete. INSTRUCTIONS. Main: This function will call getdata and print. Main is complete and should not be changed. Getdata: This function reads 10 integers and stores them into memory. There is one parameter ($a0) which holds the address of where the list of numbers is to be stored. Getdata calls the function printstr to print the prompt. Getdata is complete and should not be changed. Printstr: This function is to print a string. There is one parameter (Sa0) which holds the address of the string to print. You are to complete this function so it performs as required. This function is call from the getdata function and lire print function. Print: This function is to print the list of integers. The integers must all be on the same line of output and be separated by a comma and space (already in the data segment). Sec the example input and output below. This function must call the printstr function to print the comma string. Remember that as this function calls another, it must save and restore the $ra. Specifics: Use only the instructions covered to date. Do not use pseudo-instructions. Sec the information under MARS for preventing the use of pseudo-instructions. Make sure that your print function calls the printstr function correctly and that the stack is used correctly

Explanation / Answer

Given below is the completed code and also output. Hope it helps. If it does, please don't forget to rate the answer. Thank you very much.

.data
.space 40 # set aside 40 bytes for 10 integers
prompt: .asciiz "Enter a number " # address 0x10010028
comma: .asciiz ", " # address 0x10010038
.globl main
.text
main:
lui $a0, 0x1001 # get start of data segment
jal getdata # call getdata function
  
lui $a0, 0x1001 # get start of data segment
jal print # call print function
  
ori $v0, $0, 10 # set command to exit
syscall # end program
  
# printstr
# paramters: $a0 holds address of string to print
# purpose: print the string parameter
printstr:
ori $v0, $0, 4
syscall
jr $ra
  
  
getdata:
addi $sp, $sp, -4 # allocate space on stack
sw $ra, 0($sp) # save $ra
ori $t1, $a0, 0 # address of array
lui $t1, 0x1001 #start of data
ori $a0, $a0, 0x0028 # address of prompt
ori $t0, $0, 10 # counter
top: beq $t0, $0, ret # while not 0
jal printstr # call function to print prompt
ori $v0, $0, 5 # set command to read integer
syscall # read int
sw $v0, 0($t1) # save int in memory
addi $t1, $t1, 4 # increment to next location
  
addi $t0, $t0, -1 # decrement counter
j top # repeat
  
ret: lw $ra, 0($sp) # restore return address
addi $sp, $sp, 4 # clean up stack
jr $ra # return from call
  
# print
# parameter: $a0 holds address of list in memory
# purpose: print the list separated by commas
print:
addi $sp, $sp, -4 # allocate space on stack
sw $ra, 0($sp) # save $ra

ori $t1, $a0, 0 # address of array
ori $a0, $a0, 0x0038 # address of commal
addi $t2, $a0, 0 #save the address of comma in $t2
ori $t0, $0, 9 # counter
  
#display 1st int
lw $a0, 0($t1) #load int from array
ori $v0, $0, 1 #command to print int
syscall

addi $t1, $t1, 4 #address of 2nd int
#display the other 9 numbers
loop:   
beq $t0, $0, print_ret # while not 0
addi $a0, $t2, 0 #store address of comma
jal printstr # call function to print comma
lw $a0, 0($t1) #load int from array
ori $v0, $0, 1 #command to print int
syscall
addi $t1, $t1, 4 # increment to next location
  
addi $t0, $t0, -1 # decrement counter
j loop # repeat


print_ret:
lw $ra, 0($sp) # restore return address
addi $sp, $sp, 4 # clean up stack
jr $ra # return from call

output

Enter a number 2
Enter a number 4
Enter a number 6
Enter a number 8
Enter a number 10
Enter a number 12
Enter a number 14
Enter a number 16
Enter a number 18
Enter a number 20
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
