Project 5

Requirements Specfication

Write a program that will accept the monthly sales for the twelve months of a year. Declare two arrays in main, one for the sales, and one for the the names of the months. Use three additional functions:

One to get the monthly sales and store them in the array. When getting, the sales, you must make sure the sales are in the range of 0.00 - 150,000.00. (The user will not input the commas.)
One to print out the average monthly sales, and the name of the month that had the highest sales and the name of the month that had the lowest sales.
One to print out the name of each month and the amount of sales for that month.

Example Output

In the following example, the program displays what is in Blue and the user types what is in Red.

Enter the sales for January:   100498.50
Enter the sales for February:  498.50
Enter the sales for March:     99006.03
Enter the sales for April:     898.23
Enter the sales for May:       10022.34
Enter the sales for June:      25432.75
Enter the sales for July:      36498.23
Enter the sales for August:    44853.43
Enter the sales for September: 75002.99
Enter the sales for October:   44325.82
Enter the sales for November:  23375.07
Enter the sales for December:  87869.81

Highest Sales were in January:

Lowest Sales were in February

Average Sales were 12345.67:

January  :100498.50
February :   498.50
March    : 99006.03
April    :   898.23
May      : 10022.34
June     : 25432.75
July     : 36498.23
August   : 44853.43
September: 75002.99
October  : 44325.82
November : 23375.07
December : 87869.81

Sample Of Passing A 2-demensional Array

#include <stdio.h>

void printArray( char m[ ] [ 15 ] );

int main( void )
{
    int i;
    float sales[ 12 ] = { 1.0, 2.0, 3.0,  4.0,  5.0,   6.0,
                          7.0, 8.0, 9.0, 10.0, 11.0,  12.0 };
               
    char months[ 12 ][ 15 ] = { "January", "February", "March",
                                "April", "May", "June",
                                "July", "August", "September",
                                "October", "November", "December"} ;

     for( i = 0; i < 12; i++ )
     {
         printf( "%-9s:  %7.2f\n", months[ i ], sales[ i ] ); 
     }
     
     printArray( months );

     return 0;
}

void printArray( char m[ ] [ 15 ] )
{

     int i;

     for( i = 12; i > 0; i-- )
     {
         printf( " %-9s\n", m[ i ] );
     }

}
