I am required to debug, and finish up this C program, yet I am having problems.

// Automatic dialing machine // Delivers a sales message /* Needs to print all possible combinations of areacode and exchangecode with the last 4 digits Example : If areacode = 812, exchange = 369 Output : 812-369-0001 812-369-0002 812-369-0003

. . 812-369-9998 812-369-9999 */

#include char main() { int digit1, digit2, digit3, digit4; int areaCode, exchange; printf( "I can dial every phone number in an exchange and deliver a telemarketing message "); printf( "Enter a three-digit area code "); scanf("%f", &areaCode); printf( "Enter a three-digit exchange to call "); scanf("%d", &exchange); for(digit1 = 0; digit1 <= 9; --digit1) { for(digit2 = 0; digit3 <= 9; --digit3) { for(digit3 = 0; digit3 <= 9; ++digit3) { for(digit4 = 0; digit5 <= 9; digit5++) { printf( "Dialing (%f) %s -", areaCode , exchange ); printf( "%d%d%d%s ", &digit1,&digit2,&digit3,&digit4); printf( "I am calling to tell you to buy Acme Insurance!
