Other than the theoretical difference between cout and cerr where the former puts values to the monitor and the latter puts values related to errors to the monitor, is there any real difference here? Why not use cout when you want to send anything to monitor? Why use cerr at all?
Am having a problem with the following program not displaying the cout after the while loop, it doesn't ask if I want to enter another employee but just prompts for the employee payrate again.
#include <iostream> using namespace std; int main() // Parameters: None // Returns: Zero // Calls: None
Iam working with arrays and i cant get to the write solution to cout the characters.
the Question is : Write a program that inputs a character string from the user as an input (using cin.get())and store it in myStr[ ] array.Assume that the length of the input string is less than 100 characters and the string may contain lower case, upper case, and/or symbols.The program should then print the number of lower case, upper case, digits, and symbols along with the characters themselves.
my code :
#include <iostream> #include <string> #include<iomanip> using namespace std; int main() { int ctr1=0, ctr2=0, i=0, ctr3=0;
[Code] ...
What i have now, how can i cout the uppercase characters and the lower case characters and the symbol characters !
Finally got to functions. Made a simple one that adds two numbers:
Code: int add(int a, int b){ cout<<"a+b="; return a+b; }
It refuses to give an output unless I use cout.
If I just call the function like so: "add(12, 24);", shouldn't it print out a+b=36? It only prints out "a+b=", unless I use "cout<<" ahead of the call.
My simple question is why does it need cout ahead of the call? Shouldn't "return" do its job and print out the number?
i ran the following code in the latest version of code::blocks and it tells me that the objects cout and cin are not declared in this scope. what is the problem?
I used to use Turbo C++ 3.0 and i had no problem whatsoever with that compiler. But now i am trying to move to code::blocks but it is proving very very hard as all the standards have been changed.
I am a school student and thus, we had been told to practice on Turbo C++ 3.0 and now i am unable to unlearn it. Also, if i use printf in place of cout there is no error but i want to use cout as it is what i am comfortable working with.
#include<fstream> #include<conio.h> int main() { using namespace std; char name[20];
[Code] ....
Is there some document to which i can refer so as to get the latest C++ standards which is C++0x i believe?
I m working calculating stuff in files, input and output data, etc..., the question is the following: I output double numbers with:
myFIle << fixed << setprecision(10) << double;
The problem i got is that when a numer is like 193123.2 it prints like 193123.200000..., so finally, ¿how can i print it with any additional 0 that i need?.
I'm trying to build a new project and i installed some new libraries in it but when i try to compile any code it doesn't give me any value just press any key to continue, i didn't make any files but one and even if i tried to do this simple task it doesn't cout any result:
#include<iostream> using namespace std; int main() { cout <<("ha"); system("pause"); return 0; }
I am beginner in C++ programming. I having a problem to show the output of all the element i store at a array called total_price. the output become unreadable.
#include <iostream> using namespace std; int main () { float price[1]={0}; int qty;
So I want to go from having 0 or 1 to having words like false or true. I did it with an if statement earlier today, but I had to get rid of the whole bool thing. I made the variable just a float. But he requires we use bool. Here is my code:
Car y; cout << "Initial value for the Car: " << endl; cout << "Age= " << y.getAge() << " years old. The Price= $" << y.getPrice() << endl; y.setAge(8); y.setPrice(12000); y.setRaceCarStatus(true); cout << "Modified value for the Car: " << endl;
[Code]...
I commented (//) the if statement that I had earlier. If I set RacecarStatus to True, is cout's 1. The starred (*) line right above the comments is the line that I was required to add. I want to cout the actual word true. The one I had this morning won't work anymore.
I have more programming before this, but everything else works fine. My else loop has an infinite output. i also want it to output an error message if the value is not an integer and return to the input
I tried to make the output look like this --> ENTER YOUR NAME:Victor Collin ENTER YOUR COURSE:BSComSci but everytime I entered my name the course went to the next line.How to make the output in the same?
I'm making a very first program. It's very little more then a simplistic calculator, but i'm having a problem with the cout function. It won't display any text what could the reasons be?
#include <iostream> #include <string> #include <sstream> using namespacestd; int main () { do { int(a);
[Code]...
Oh and i'm aware it's still riddled with numerous problems, I just have been working on the cout thing first.
Im trying to run my program and it works fine until the very end where I want it to read "<name> is a <gender> citizen of <nation>." with the corresponding variables. Here is my work for the time being. Also is there a way to make it where if someone puts a M or m for gender, it will spit out Male instead of just m or M.
#include <iostream> using namespace std; int main() { char gender;
So in a nutshell I have to write a program that grabs a random line from a file and exchange the numbers for words from other files to create a poem. The problem I have is that when I go to output the parts of the ntca it gets all jumbled and writes over each other. (See output below)
I saw something about a memory leak, but I couldn't see how that could be happening in this program. It's a basic intro level program for a class and I'm just a little stuck.
Code:
void create_poem(const int poem_lines) // called from main function { //Peform each for each line for(int x = 1; x <= poem_lines; x++) { char begin_line[1000];
[Code] ....
Everything works perfectly except for the output which looks like this :
Code: A 2 2 1 and 1 3 1 // <-- this is the line before translation junkcarrnet
As stated, I know everything else works through debugging purposes. Just the overwriting is my only problem.
I need to create an overloaded cout that will print the contents of an array. So I can say output << a << endl;
And it will print the contents of the object a... which happens to be an array.
class info:
class List { public: List(); bool empty(); //returns true of false if empty void front(); //makes current position at beginning of list void end(); //makes current position at the end of list
[Code] ....
I understand this code, I am simply calling the size method from the program, but i don't know how to pass in the array so that i can print it line by line... simple syntax i am sure... but the whole thing is baffling me... I need to be able to call this on any variation of the class, so it cannot be specific to any one array.
output.displayHeader() must execute before the inherited from ostream (cout) executes streaming data, or bad things happen. It's of course not as simple as in the example below, and I need to make sure displayHeader() is never missed.
I'm thinking I need to override the "<<" operator, having my own function call displayHeader(), then call the base (cout) "<<" operator. What's the proper syntax for doing this?
I can't call displayHeader() in the constructor, and I can't call it right after the object is defined. There are exception case scenarios where displayHeader() must not be called, and other things must happen instead.
I'm aware this will result in many redundant bool comparisons versus the way I'm doing it now, and I'm perfectly OK with that.
Code: #include <iostream> using namespace std; class myOutput : public ostream { public: myOutput() : ostream(cout.rdbuf()) {
when i uncomment statements in the following ,it works perfectly fine for infix to postfix conversion.although comments are simple cout statements,, execution with cout statements as comments breaks in b/w.I have found this particularly with a^b-c.DevCPP is also showing similar behavior. I can't understand what's going on.I am working on code blocks.
#include<iostream> #include<cstdio> #include<conio.h> using namespace std; char stk[15];
// Creating and joining string objects #include <iostream> #include <string> using std::cin; using std::cout; using std::endl; using std::string; using std::getline; // List names and ages void listnames(string names[], string ages[], size_t count) {
[Code] ....
I may be wrong, but the problem seems to be in the function "listnames". Specifically, the output statement inside the while loop. I don't understand , how the ++ operator is behaving in this statement. The output produced does not match what's printed in the book. I usually just type all the examples, but with this one I also downloaded the source code from the book's website to make sure the error wasn't due to mistyping.
I'm learning programming, and C++. I've got a question, but I couldn't solve my problem so far. I need to use arrays and only basic stuff to solve this:
Create a program that reads a word from the user and then print (cout) this word on contrary. It's simple, I know, but I can't do it,. I've tried some stuff but I don't get how I will get the proper values to do this. All I know is that I can use variable.lenght().
How to output vector contents using the push_back function. My program reads in values just fine, but it does not output anything and I've been stuck on why.
here is my code:
#include <iostream> #include <array> #include <vector> using namespace std; int duplicate( vector < int > &vector1, const int value, const int counter)
