From this, you surmise that ROW and COL must have been compile-time constants. What are their values? (Hint: in order to answer this question, it helps to know how 2-dimensional arrays are stored in memory in row-major order.)

The number of ROW or row of the 2-dimensional array is 2

The number of COL or column of the 2-dimensional array is 3

Explanation:

The C source code function fetch_aval which is programmed to return an integer value was compiled to the MIPS assemble code;

fetch_aval:

andi $5, $5,0x0007

sll $6,$6,2

 sll $2,$5,3

subu $2,$2,$5

 sll $2,$2,3

 addu $2,$2,$4    

 addu $6,$6,$2

lw $2,0($6)

j $31

Where the statement "sll $6,$6,2" defines the row length of the array to be 2 (at the end of the statement) and "sll $2,$5,3" gives the column length of 3.

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
