Answer:

The challenge of cost control

The challenge of competence

The challenge of reduced system delivery times.

Explanation:The Challenge of Cost control is a major challenge affecting the software engineering in the 21st century,the cost of Microchips and other hardware are constantly rising.

The challenge of competence is another major challenge affecting software engineering in the 21st century,as most software engineers lack the required competence to handle some of the issues facing softwares.

The challenge of reduced system delivery times is a major challenge likely to affect software engineering in the 21st century,as people required the software to be available in the shortest possible time.

The Gas-N-Clean Service Station sells gasoline and has a car wash. Fees for the car wash are $1.25 with a gasoline purchase of $
beks73 [17]

Answer:

d = {"R":2.89,"P":3.09, "S":3.39, "N":0}

noofgallons = input("Enter number of Gallons:")

gastype = input("Enter Gas type/; R,P,S,N")

cwr = input("Is Car Was Requieed")

if(gastype == "R"):

   gal == nooffgallons * d['R']

   if (cwr=="y" and gal<10):

       gal+=3.00;

       elif(cwr=="y" and gal>=10):

           gal+=1.25

           elif(cwr=="n"):

               gal=gal

   elif(gastype==P):

       gal== nooffgallons * d['P']

       if(cwr="y" and gal<10):

           gal+=3.00;

           elif(cwr=="y"and gal>=10):

           gal+=1.25

           elif(cwr=="n"):

               gal=gal

       elif(gastype ==S):

           gal=noofgallons *d['S']

           if(cwr="y" and gal<10):

               gal+=3.00;

               elif(cwr=="y"and gal>=10):

                   gal+=1.25

                   elif(cwr=="n"):

                       gal=gal

                       

                       

print("tptal cost paid"+ gal)

The above program uses a dictionary for storing gasoline types and their cost, and dictionary is always constant, and hence its fulfilled the requirement of keeping it constant. And car wash is treated accordingly. And if elif else ladder has been used to calculate the total number of gallons.

Rest part is self explanatory.

The code is self explanatory.

Write a flowchart and C code for a program that does the following: Within main(), it asks for the user's annual income. Within
Fiesta28 [93]

Answer:

I am writing a C program:

#include <stdio.h> //to use input output functions

void printIt(double annual_in){ //function printIt

   if(annual_in >90000) //check if the income is greater than 90000

   printf("Congratulations. Doing great!"); //print this message if income value is greater than 90000

   else //if annual income is less than 90000

   printf("You WILL make $50,000, if you keep going"); } //print this message if income value is less than 90000

int main() //start of main() funciton body  

{   double income; //declares a double type variable income to hold annual income value

   printf("Enter annual income: "); //prompts user to enter annual income

   scanf("%lf",&income); //reads income value from user

   printIt(income); } // calls printIt method by passing input income to that function

     

Explanation:

The program is well explained in the comments mentioned with each statement of the program. The flowchart is attached.

First flowchart flow1 has a separate main program flowchart which reads the income and calls printIt function. A second flowchart is of prinIt() method that checks the input income passed by main function and displays the corresponding messages and return.

The second flowchart flow2 is the simple flowchart that simply gives functional description of the C program as flowchart is not where giving function definitions is important. Instead of defining the function printIt separately for this C program, a high-level representation of functional aspects of this program is described in second flowchart while not getting into implementation details.

I can't imagine any reason _______ he should have behaved in such an extraordinary way. for that why how
professor190 [17]
<span>I can't imagine any reason "why" he should have behaved in such an extraordinary way. If we were to use "how" in that sentence it would contradict the context. We are obviously talking about a situation that has happened so we know that "he" has in fact acted in an extraordinary way but we don't know "why" he acted that way. Therefore "why" is the correct term to use.</span>
