Here is the revised program, with an addition
to the printf statement that displays the recorded trade
description:
#include#include /* Define the trade apparatus */ struct trade {double price; int number; char *description;}; /* Define trade array and input buffer array*/ struct trade *trade_pointers[100]; char input_buffer[100]; /* Define price-computing function */ double trade_price (struct trade *x) { return x -> price * x -> number; } main ( ) { /* Declare various variables */ int limit, counter, number; double price; /* Read trade information */ for (limit = 0; 3 == scanf ("%s%lf%i", input_buffer, &price, &number); ++limit) { trade_pointers[limit] = (struct trade*) malloc (sizeof (struct trade)); trade_pointers[limit] -> price = price; trade_pointers[limit] -> number = number; trade_pointers[limit] -> description = (char*) malloc (strlen (input_buffer) + 1); strcpy (trade_pointers[limit] -> description, input_buffer); } /* Display report */ for (counter = 0; counter < limit; ++counter) printf ("%s %f %i %f\n", trade_pointers[counter] -> description, trade_pointers[counter] -> price, trade_pointers[counter] -> number, trade_price(trade_pointers[counter])); } --- Data --- F-BLD 3.3 300 T-GG 2.5 400 AX-FLY 9.9 100 AB-CH11 10.1 100 C-IBM 5.0 200 --- Result --- F-BLD 3.300000 300 990.000000 T-GG 2.500000 400 1000.000000 AX-FLY 9.900000 100 990.000000 AB-CH11 10.100000 100 1010.000000 C-IBM 5.000000 200 1000.000000
