Write C Program

Write a C program to take as input (via stdin) a valid assignment statement in C and generate MIPS assembly code to perform the given calculation(s). You can assume that each C variable name is one lowercase letter (e.g., a, b, c, etc.) and of type int. Further, positive int constants are also allowed as part of the given expression. For this script, you only need to support the addition (+) and subtraction (-) operators. Note that you should use isspace(), islower(), isdigit(), scanf(), etc. to parse the input. The MIPS code you generate must make use of registers $s0,$s1,...,$s7 to correspond to C variables and registers $t0,$t1,...$t9 to correspond to any temporary variables you need. Variables in MIPS should match those in C from left to right, meaning that the final result of the script statement must end up in register $s0. You can assume that you will not need more than the specific MIPS registers listed here. Below are a few example runs of your program. In the first example, register $s0 corresponds to C variable f, $s1 corresponds to g, and $s2 corresponds to h. bash$ ./[login to view URL] Please enter a valid C assignment statement: f = g + h - 42; The MIPS pseudocode is: add $t0,$s1,$s2 sub $s0,$t0,42 bash$ ./[login to view URL] Please enter a valid C assignment statement: x = q - 12 + j; The MIPS pseudocode is: sub $t0,$s1,12 add $s0,$t0,$s2 bash$ ./[login to view URL] Please enter a valid C assignment statement: a = x - y + 13 + x - a; The MIPS pseudocode is: sub $t0,$s1,$s2 add $t1,$t0,13 add $t2,$t1,$s1 sub $s0,$t2,$s0
