C++ :: What Is Namespace STD
Jun 10, 2014i know using namespace std; is important to wite as it contain cout,cin,etc........but is that namespace std is contained inside iostream header file OR iostream header file is contained inside namespace std ......
View 1 Replies View RelatedC++ :: Dislike Using Namespace Std?
May 4, 2013It seems as though more experienced programmers tend to write code with std::cout, std::string, etc., whereas less experienced programmers always write using namespace std;. They also tend to assume that, in code snips, it is already included.
Why is this? If it's a dislike, what's the problem with it? As stated in the namespaces tutorial on this site, a namespace can be overridden if need be. Is it the case that you have written your own namespaces? Or that you so seldom use things like the STL and stdin/out that it just isn't necessary?

View 1 Replies View RelatedC++ :: Dividing Two Floats Not Giving The Required Quotient
Jan 9, 2014Im using the remquo function in the cmath library as follows:
int quotient;
double a = remquo (10.3, 4.5, "ient);
This gives the correct remainder (a = 1.3) and quotient (quotient = 2).
Infact about 50% of the answers are right when I play around, however, trying something like:
int quotient;
double a = remquo (2.25, 1.5, "ient);
yields an incorrect quotient of 2 and remainder of 0.
I do think this has something to do with float arithmetic. I recall tinkering with the float number 0.500 and that the CPU actually saves it as 0.50000000000000231. However if my suspicion of float arithmetic as the suspect is correct, I do not understand why a tenth decimal would make such a drastic difference as changing the quotient result.
C :: Error - I Value Required As Left Operand Of Assignment
Apr 21, 2013I am getting this error when compiling my program with quincy:
Error: I value required as left operand of assignment
The program is meant to calculate how much parking costs based on the amount of hours in a park and what type of vehicle it is. the error is coming from my function definitions which i have just started to add in.
Code:
float calcCarCost (char vehicletype, int time, float car)
{
if ((time > MINTIME) && (time <= 3))
calcCarCost =( CAR * time );
}
The error is on line 72 which is:
calcCarCost =( Car * time);
I should probably point out CAR is already defined as a constant with a numerical value given and time is previously asked to be input in when the program runs.
C :: Find The Least Amount Of Coins Required To Make A Value
Mar 8, 2014Write a program in C that will allow a user to enter an amount of money, then display the least number of coins and the value of each coin required to make up that amount. The twist to this program is the introduction of a new coin - the jonnie (value = $1.26). Therefore, the coins available for your calculations are: Twonies, Loonies, Jonnies, Quarters, Dimes, Nickels and Pennies. You can assume the amount of money user enters will be less than $100.00.
User enters $4.53. Your output should be:
The least number of coins required to make up $4.53 is 4. The coins needed are:
1 Toonie $2.00
2 Jonnies $2.52
1 Penny $0.01
$4.53
I'm wondering if i'm close. I'm stuck on what to do for the output. This is what i have so far.
Code:
//Start
#include <stdio.h>
int main() {
//Get user input for amount of money
//Input
int i;
//Store input from user

C++ :: Why Asterisk Required On Smart Pointers For Assigning Value
May 19, 2013When i try to compile this code it gives me a error during run-time saying "*program name* has stopped working"
Code:
#include <iostream>
#include <memory>
using std::cout;
using std::endl;

Why is this happening? Also why do you need the asterisk on smart pointers to assign them a value? Is it just because, or is there a reason.

C++ :: Where To Put The Include Directive And Using Namespace Std With Multiple Files
Aug 23, 2014I have two files that I want to compile:
main.cpp
Code:
#include <iostream>
using namespace std;
int ReadNumber();
void WriteAnswer();
[Code] .....
The compiler complains:
io.cpp||In function 'int ReadNumber()':|
io.cpp|3|error: 'cin' was not declared in this scope|
io.cpp||In function 'void WriteAnswer()':|
io.cpp|7|error: 'cout' was not declared in this scope|
io.cpp|7|error: 'endl' was not declared in this scope|
In io.cpp file, should I put the two statements ("include <iostream>" and "using namespace std") at the top, outside of the functions?
Or should I put the two statements inside each of the functions?
