Thread: Arrays and Functions

Code:

#include <stdio.h>
main ()
{
int unitssold[10];
int empindex;
float basal[] = {158.00, 147.75, 315.00, 162.25, 220.00, 181.60, 376.90, 168.70, 293.00, 214.30}


printf( "Please enter the Units Sold for Each of the 10 Sales Persons\n" );
for ( empindex = 0 ; empindex < 10 ; empindex ++ )
{
scanf( "%d", &unitssold[empindex] );
}

End of Code (For Now )

Hey guys im kinda new to arrays and functions i need this program to calculate wages based on Commission ie, the more certain emplyees sell the more money they make, i have to use a certain commission rate as follows,
Number of Units sold Commission Rate
1 - 5 INclusive 3.80
6 - 10 Inclusive 5.40
11 - 15 Inclusive 8.60
> 15 15.20

Im just wondering how to implement this into the program, and also if the program so far is looking ok? any advice would be appreciatede guys thanks..

Question, why does my compiler give me warnings with this statement?

Code:

float basal[] = {158.00, 147.75, 315.00, 162.25, 220.00, 181.60, 376.90, 168.70, 293.00, 214.30};

But if I change the datatype to double it compiles without warnings.

Code:

warning C4305: 'initializing' : truncation from 'const double ' to 'float '
warning C4305: 'initializing' : truncation from 'const double ' to 'float '
 warning C4305: 'initializing' : truncation from 'const double ' to 'float '
warning C4305: 'initializing' : truncation from 'const double ' to 'float '

Code:

#include <stdio.h>
main ()
{
int unitssold[10];
int empindex;
float total_sal[10];
float basal[] = {158.00, 147.75, 315.00, 162.25, 220.00, 181.60, 376.90, 168.70, 293.00, 214.30};
float commission[10];

printf( "Please enter the Units Sold for Each of the 10 Sales Persons\n" );

for ( empindex = 0 ; empindex < 10 ; empindex ++ )
{
  scanf( "%d", &unitssold[empindex] );
}
if (unitssold[empindex] >= 1 && unitssold[empindex] <= 5)

{ total_sal[empindex] == unitssold[empindex]*3.80 + basal[empindex];
  commission[empindex] == unitssold[empindex]*3.80;
}

else

if (unitssold[empindex] >= 6 && unitssold[empindex] <= 10)

{ total_sal[empindex] == unitssold[empindex]*5.40 + basal[empindex];
  commission[empindex] == unitssold[empindex]*5.40;
}

else

if (unitssold[empindex] >= 11 && unitssold[empindex] <= 15)
{ total_sal[empindex] == unitssold[empindex]*8.60 + basal[empindex];
  commission[empindex] == unitssold[empindex]*8.60;

}

else
{ total_sal[empindex] == unitssold[empindex]*15.20 + basal[empindex];
  commission[empindex] == unitssold[empindex]*15.20;
}

printf( " Total salary for no 2 is %f and the Commission is %f" ,total_sal[2] , commission[2]);

}

/end code/

Ok this seems ok to me but when it compiles it doesnt run properly, it gives the wrong commission and Total salary in the printf statement at the end of the program, any ideas guys? Probably did something completely stupid

Thanks Dave

}
float commission (float amnt_sld)
{

Anyone know where to go with this function? Not really sure how to use functions properly, also i still dont understand why it doesnt return anyvalues, just 0s
