Question

        JAVA 
        Write a psedudocode. A psedudocode is
        a series of step by step instructions, in basic English
        that outlines how you will write your program.
        
        Here is what I expect to see:
        A) How does your program take three inputs from the keyboard?
                
        B) How do you make sure at least two of the inputs are single digits
        between 0 and 9?

    C) How do you make sure the program takes a character 
        from the keyboard, representing one of five operations 
        from the keyboard: +(addition), -(subtraction), 
        *(multiplication), /(division), and ^(exponentiation)?

    D) How do you make sure the program outputs the description 
        of the operation in plain English, as well as the numeric result?

Answer 1

PSEUDOCODE:

int a, b;
char c;
do
{
   a=INPUT int;
}while(a<0 or a>9);
do
{
   b=INPUT int;
}while(b<0 or b>9);
do
{
   c=INPUT char;
}while(c!='+' and c!='-' and c!='*' and c!='/' and c!='^');
int result;
switch(c)
{
   case '+':
   result=a+b;
   break;
   case '-':
   result=a-b;
   break;
   case '*':
   result=a*b;
   break;
   case '/':
   result=a/b;
   break;
   case '^':
   result=a^b;
   break;
}
OUTPUT result;

int a, b; char c; do a=INPUT int; } while(a<0 or a>9); b=INPUT int; }while(b<0 or b>9); do COINPUT char; }while(c!='+' and c!='-' and c!='%' and c!='/' and c!='1'); int result; switch(c) case '+': result=a+b; break; case '-': result=a-b; break; case '*': result=a*b; break; case '/' : result=a/b; break; case 'A': result=a1b; break; OUTPUT result;

We use the do-while loops to validate the inputs and then we use a switch-case to calculate the result and display it.
