Hi,
I am trying to write a program (exercise from a book) that reads in information about salespersons and products they sold and summarize output in tabular format. I am nearly there, when i compile it there are lots of errors (i'm very new 2 c, about 2 weeks), and later i fixed all of them except for two. Pls spot them for me. Thnx in advance! Also if possible, is there a way to make the code even better? Thnx again.
Code:
/* Read in salesperson and product information,
process them and output in tabular format. */
#include <stdio.h>
#define PERSON 4
#define PRODUCT 5
/* Function prototype */
void output( const int array[][ PRODUCT ], int person, int product );
int main()
{
int sales[ PERSON ][ PRODUCT ] = { 0 };
int i, j; /* Loop counters */
for ( i = 0; i <= PERSON - 1; i++ ) {
for ( j = 0; j <= PRODUCT - 1; j++ ) {
printf( "Enter cost of product %d for sales-person %d (Enter -1 if nothing): ",i, j);
scanf( "%d", &sales[ i ][ j ] ); /* Store input in array */
}
printf( "\n" );
}
output( sales, PERSON, PRODUCT ); /* Print summary */
return 0;
}
void output( const int array[][ PRODUCT ], int person, int product )
{
int i, j, k, total = 0;
printf( "\n ***Report***\n" ); /* Print title */
printf( "%s%4s%4s%4s%6s", "Person 1", "Person 2", "Person 3", "Person 4",
"Totals" ); /* Column headers */
for ( i = 0; i <= person + 1; i++ ) {
printf( "\n" );
printf( "Product %d", i );
if ( i != 4 ) {
for ( j = 0; j <= product; j++ ) {
if ( array[ i ][ j ] == -1 )
printf( "%4s", "/" );
else {
printf( "%4d", array[ i ][ j ] );
total += array[ i][ j];
if ( j == 4 )
printf( "%4d\n", total );
}
total = 0;
}
}
printf( "\nTotals" );
printf( "%4d", array[ 0 ][ 0 ] + array[ 0 ][ 1 ] + array[ 0 ][ 2 ] + array[ 0 ][ 3 ] + array[ 0 ][ 4 ] );
printf( "%4d", array[ 1 ][ 0 ] + array[ 1 ][ 1 ] + array[ 1 ][ 2 ] + array[ 1 ][ 3 ] + array[ 1 ][ 4 ] );
printf( "%4d", array[ 2 ][ 0 ] + array[ 2 ][ 1 ] + array[ 2 ][ 2 ] + array[ 2 ][ 3 ] + array[ 2 ][ 4 ] );
printf( "%4d", array[ 3 ][ 0 ] + array[ 3 ][ 1 ] + array[ 3 ][ 2 ] + array[ 3 ][ 3 ] + array[ 3 ][ 4 ] );
for ( k = 0; k <= 50; k++ )
printf( "*" );
printf( "\n" );
}
