Question

Write a SPIM assembly language program convert.s. The program will do the following: 1. Prompt the user to enter a letter indicating Celsius or Fahrenheit C or c indicates that temperature entered is in Celsius. F or f indicates that temperature entered is in Fahrenheit. If the letter entered is not C, c, F, or f print out error message "Wrong Letter!". 2. Prompt the user to enter an integer indicating the temperature matching the letter just entered. 3. Convert the temperature to its counter part. 4. Here are the two formulas for your reference. F = (9 * C/5) + 32 C = 5 * (F - 32)/9 5. Print out the converted values with appropriate message.

Explanation / Answer

Answer:

Assembly Language Code:

.LC0:
        .string "1.Celsius to Fahrenheit"
.LC1:
        .string "2.Fahrenheit to Celsius"
.LC2:
        .string "Choose between 1 & 2 : "
.LC3:
        .string "Enter the temperature in Celsius : "
.LC6:
        .string "Temperature in Fahrenheit = "
.LC7:
        .string "Enter the temperature in Fahrenheit : "
.LC9:
        .string "Temperature in Celsius = "
