需要帮助替换文字 [英] Need help replacing text
问题描述
使用C ++在这里苦苦挣扎，但我发现它同时很有趣。有任何好书或网站可以帮助这个项目吗？
对于以下内容 - 我想用cin和cout语句替换前三个语句，以便可以从用户获取age，salary和distance_to_the_moon的值。这使程序变得灵活，以便每次运行时都使用不同的数字。
#include< iostream.h>
void main（void）
{
int age = 32;
浮动工资= 25000.75;
long distance_to_the_moon = 238857;
cout< < ？员工是？ <<年龄<< ？岁了？ << endl;
cout<< ？员工赚了？ <<工资<< endl;
cout<< ？月亮是？ << distance_to_the_moon<<
？离地球几英里？ << endl;
}
＃评论显示在文件顶部，表示作业编号问题编号和你的名字
＃税额是一个常数值.085
＃用户从键盘输入成本
＃10％的折扣将被声明为常数和给定的成本确定
＃一个新的变量将被声明为new_cost，将是成本减去折扣
＃税将被计算出来10％的折扣后的new_cost取消了成本
＃总数将是new_cost加上税金
＃用户将从键盘输入amount_paid
＃更改将是amount_paid减去总额
＃，成本，折扣，新成本，税金，总额和amount_paid都将以适当的格式打印。
#include< iostream.h>
void main（）
{
浮动成本= 15.50; //物品的成本
浮动sales_tax = 0.06; //销售税为6％
浮动金额_paid = 20.00; //买方支付的金额
浮动税，变更金额，总金额; //销售税，买方变更和总账单
税=成本* sales_tax;
总计=成本+税;
更改= amount_paid？总计;
cout<< ？物品成本：$？ <<成本<< ？税：$？ <<税<<
？\tTotal：$？ <<总<< endl;
cout<< ？客户变更：$？ <<改变<< endl;
}
？ <<工资<< endl;
cout<< ？月亮是？ << distance_to_the_moon<<
？离地球几英里？ << endl;

Struggling greatly here with C++ but I find it interesting at the same time. Any good books to buy or web sites to help with this program?
For the following - I''m suppose to replace the first three statements with cin and cout statements so that the values for the age, salary, and distance_to_the_moon can be obtained from the user. This make the program flexible so that everytime is is run different numbers are used.
#include <iostream.h>
void main(void)
{
int age = 32;
float salary = 25000.75;
long distance_to_the_moon = 238857;
cout << ?The employee is ? << age << ? years old? << endl;
cout << ?The employee makes $? << salary << endl;
cout << ?The moon is ? << distance_to_the_moon <<
? miles from the earth? << endl;
}
# comments appear at the top of the file indicating the assignment number question number and your name
# the tax amount is a constant value of .085
# the user enters from the keyboard the cost
# a discount of 10% will be declared as a constant and given on the cost that was entered
# a new variable will be declared called new_cost and will be the cost minus the discount
# the tax will be figured out on the new_cost after the discount of 10% is taken off of the cost
# the total will be the new_cost plus the tax
# the user will enter the amount_paid from the keyboard
# the change will be the amount_paid minus the total
# and the cost, discount, new cost, tax, total, and amount_paid will all be printed with appropriate format.
# include <iostream.h>
void main()
{
float cost = 15.50; // The cost of an item
float sales_tax = 0.06; // Sales tax is 6 percent
float amount_paid = 20.00; //The amount the buyer paid
float tax, change, total; // Sales tax, buyer change and total bill
tax = cost * sales_tax;
total = cost + tax;
change =amount_paid ? total;
cout << ?Item Cost: $? << cost << ? Tax: $? << tax <<
?\tTotal: $? << total << endl;
cout << ?Customer change: $? << change << endl;
}
? << salary << endl;
cout << ?The moon is ? << distance_to_the_moon <<
? miles from the earth? << endl;
}
