Question
could I get some help replacing the output code with a decision statement that prints more informative messages for the cases where the data is
could I get some help replacing the output code with a decision statement that prints more informative messages for the cases where the data is in the array and the data is not in the array
I need to implement a MIPS version of the java code below into the code replacing the output statement that is in bold thanks.
if (index != -1) print "x[", index, "]=", key else print "The value", key, " was not found"
CODE #
.data
program: .asciiz "Array Search Program" prompt: .asciiz "Enter search value: " txt1: .asciiz "x[" txt2: .asciiz "]=" txt3: .asciiz "The value " txt4: .asciiz " was not found" txt5: .ascii "Search returns " .align 2 x: .word 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31 .global main
