Summary: Read 2 integers and print their sum
You have been given practice_q1.s , a MIPS assembler program that reads one number and then prints it.
Add code to practice_q1.s to make it equivalent to this C program:
// print the sum of two integers
#include <stdio.h>
int main ( void ) { int x , y ;
scanf ( "%d" , & x ); scanf ( "%d" , & y ); printf ( "%d \n " , x + y );
return 0 ; }
In other words, it should read 2 numbers and print their sum.
For example:
1521 mipsy practice_q1.s 5 8 13 1521 mipsy practice_q1.s 118 26 144 1521 mipsy practice_q1.s 42 42 84
No error checking is required.
Your program can assume its input always contains two integers, and only two integers.
You can assume the value of the expression can be represented as a signed 32 bit value. In other words, you can assume overflow/underflow does not occur.
Your solution must be in MIPS assembler only.
