Declare a string in the data section such as:

.data

string: .asciiz "in a hole in the ground there lived a hobbit" Notice there are extra spaces in this string. Write an MIPS program that capitalizes the first letter of each word, so that after running your program the data will look like this: .data

string: .asciiz "In A Hole In The Ground There Lived A Hobbit" Assume that the data comprises only upper and lower case characters and spaces, and alters a character only if it is lower case, and follows a space or is the first character on the line. Print the strings before and after translation by using the syscall print string service.

Here is my solution:

.text .globl main

main: li $v0, 4 # Print the original string. la $a0, string syscall

loop: lb $t1, string($t0) nop nop beq $t1, $0, end # if ($t1 == NULL) print the result nop nop bne $t0, $0, next # Check if first character is lower case nop nop blt $t1, 97, next2 # Convert from lower case to upper case nop nop bgt $t1, 122, next2 nop sub $t1, $t1, 32 sb $t1, string($t0) addi $t0, $t0, 1 j loop

next: bne $t1, 32, next2 # if ($t1 == ' ') check for next character nop addi $t0, $t0, 1 lb $t1, string($t0) nop nop blt $t1, 97, next2 # Convert from lower case to upper case nop nop bgt $t1, 122, next2 nop sub $t1, $t1, 32 sb $t1, string($t0) addi $t0, $t0, 1 j loop

next2: addi $t0, $t0, 1 j loop

end: li $v0, 4 # Print a new line. la $a0, newline syscall

li $v0, 4 # Print the new string. la $a0, string syscall

li $v0, 10 # End the program. syscall

.data string: .asciiz "in a hole in the ground there lived a hobbit" newline: .asciiz " "

Here is my output:

"In A Hole In The Ground There Lived A hobbit"

I can't seem to capitalize the letter "h" in "hobbit". Can someone help me fix this?
