1-a) Write a program which sums two numbers specified by the user at runtime We'll write a program named add2.asm that computes the sum of two numbers specified by the user at runtime and displays the result on the screen. The algorithm that this program will follow is: 1. Read the two numbers from the user. We'll need two registers to hold these two numbers. We can use $t0 and $t1 for this. a. Get first number from user, put into $t0. i. load syscall read_int into $v0, ii. perform the syscall, iii. move the number read into $t0. b. Get second number from user, put into $t1 i. load syscall read_int into $v0, ii. perform the syscall, iii. move the number read into $t1.
