Question

Write a program that stores the following prices in a global array: 9.92, 6.32, 12.63, 5.95, 10.29. The program should also create two automatic arrays names units and amounts, each capable of storing five double-precision numbers. Using a for loop and a scanf() function call, have the program accept five user-input numbers into the units array. The program should store the product of the corresponding values in the prices and units arrays in the amounts array (for example, amounts[1] = prices[1] * units[1]) and display the price, units and amount in a table. Use pointer references to access the array elements. Sample output:

Explanation / Answer

#include<stdio.h>
#include<conio.h>

float prices[5]={9.92,6.32,12.63,5.95,10.29};   //declare global float array prices
void main(){
   float units[5],amounts[5];   //declare float array units and amounts
   float total;   //declare float varaiable total to sum up and store the amounts
   int i=0;   //declare loop varaiable
   clrscr();   //clear the screen
   for(i=0;i<5;i++){   //iterate 5 times
       printf("Enter units[%d]:",i);   //prompt for input
       scanf("%f",(units+i));   //accept the input
   }
   for(i=0;i<5;i++){   //iterate 5 times
       amounts[i]=prices[i]*units[i];   //calculate amount for each item in arrays
   }
   printf(" Price Units Amount ");
   printf("----- ----- ------ ");
   total=0;   //initialize total to 0
   for(i=0;i<5;i++){
       printf("$ %.2f %.2f $ %.2f ",*(prices+i),*(units+i),*(amounts+i));   //display the calculated price, unit and amount for each item in array
       total+=amounts[i];   //add each amount to total
   }
   printf(" ");
   printf("----- ----- ------ ");
   printf("Total:      $%.2f",total);   //display the total
   getch();   //wait at the console after displaying the output till any key is pressed to exit the program
}
