Help, im a student that has to write a program for counting coins. Half of the program works but the other half doesn.t

should have the following parameters.

output is:

Name

Date

total number of coins

number of quarters

number of dimes

nickels

pennies

I got all that to work but that math doesnt work

for the Value of the coins and the total coin value, can someone please tell me what im doing wrong?

#include <iostream> //----->Header file

#include <string.h>

#include <math.h>

void main()

{

double quarter_value(0.25);

double dime_value(0.10);

double nickel_value(0.05);

double pennies_value(0.01);

int num_quarters;

int num_dimes;

int num_nickels;

int num_pennies;

int total_num_coins;

int total_val_coins = quarter_value + dime_value + nickel_value + pennies_value;

int total_quarter_val = quarter_value * num_quarters;

int total_dime_val = dime_value * num_dimes;

int total_nickel_val = nickel_value * num_nickels;

int total_pennies_val = pennies_value * num_pennies;

char full_name[32],

date[12];

cout << "Please Enter Your Name: ";

cin >>full_name;

cout <<endl;

cout << "Please Enter Today's Date: ";

cin >>date;

cout <<endl;

cout << "Enter the Number of Quarters: ";

cin >>num_quarters;

cout <<endl;

cout << "Enter the Number of Dimes: ";

cin >>num_dimes;

cout <<endl;

cout << "Enter the Number of Nickels: ";

cin >>num_nickels;

cout <<endl;

cout << "Enter the Number of Pennies: ";

cin >>num_pennies;

cout <<endl;

//Total Number of Coins and Value

//total_num_coins=num_quarters+num_dimes+num_nickels +num_pennies;

//total_val_coins=quarter_value+dime_value+nickel_va lue+pennies_value;

//Total of each coin

//total_quarter_val= quarter_value*num_quarters;

//total_dime_val=dime_value*num_dimes;

//total_nickel_val=nickel_value*num_nickels;

//total_pennies_val=pennies_value*num_pennies;

cout <<"Name:" << full_name <<endl <<endl;

cout <<"Date:" << date <<endl <<endl;

cout <<"Total number of coins input:" << total_num_coins <<endl;

cout <<"Number of Quarters:" << num_quarters <<endl;

cout <<"Number of Dimes:" << num_dimes <<endl;

return 0;
