Question

In this part of the assignment, you will write MIPS assembly code to replace characters in a string.

This program asks the user for a string named string and two characters orig and new. It then replaces each instance of the character orig found in string with the character new. It outputs the resulting string and the number of substitutions that were made. For example, if string were "wow", orig were 'w', and new were 'b', the program would output the resulting string of "bob" and 2 as the number of substitutions.

this is a MIPS programming problem.

Answer 1

Code:-

li $t1,0 la $50, string lb $51,orig lb $s2,new #count #string base address #orig #new FOR_LOOP: lb $t2,($s0) beq $t2,$0, LOOP_EXIT bne $t2,$51, NEXT sb $52,0($50) addi $t1,$t1,1 NEXT: addi $50,$50,1 j FOR_LOOP LOOP_EXIT: la $a0, string addi $v0,$0,4 syscall li $v0,10 syscall
