I mean something like this:
Enter a character:
You choosed " / "
On which line do want the character?
You choosed "Line 1 and 2"
Where do you want the the to appear on the line? (left or right)
You choose left.
Results:
Line 1. / hello
Line 2. / hello
I have a small loop that gets the user input, as well as acts as input validation to make sure he or she doesn't enter a value that is not within the specified range.
The user is supposed to enter a month number. E.g. if he or she chooses February, then enter 2, or December, 12.
It works correctly if they type a number that is not in the range, but goes into an infinite loop if, say, they type a string such as "month".
Code:
int main() {
// Variable Declaration(s)/Initialization(s)
int month=0;
// Get input
cout<<"Enter a month";
cin>>month;

Is this a good way of writing this program?I wanted to start fresh with my new code though and a better title.Basically, I took what I learned from my questions in that thread and managed to build a list of musical notes( octaves, frequencies, sharp symbols, basically everything ).
Code:
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <math.h>
#define MAX_NOTES 88 /* 88 keys on a standard piano */
[code]...
I already know the frequencies are correct( they are rounded, but they should be close enough to the value ), but I wasn't so sure about the note labels. Obviously though, I'm not done with this program and I will be adding most of the functions Anduril suggested to take a text file and convert it into music. I just wanted to make sure I had everything correct before moving on. I probably didn't do the GetNextOctave() and GetNextNote() functions very efficiently so need suggestions on those functions also.
At the moment I am making program that will use a 2d selection of "cells" to make a "map" of sorts. However, the size will not be known until run time.
I figured using an array would good, because once the size is chosen it won't be changed. However I can't create an array without using a constant.
So the first question is, can I create a constant at run-time with a user entered value that can then be used for an array size? If so, how?
Otherwise, what are my options to achieve this? I know vectors can be used, but A, my compiler keeps giving me problems even when C&P some code bits (yes I even remembered to #include and such) and B, I noticed that vectors reserve extra memory for when the size changes but this is bad (well my dinky little program won't notice, but trying to set good habits as I learn, so I'm keeping it in mind) as I don't need and don't want to allow the size to change after creation.
Which leads to number three, if I do have to use vectors, how can I prevent any accidental size changes after the initial size is determined?
I have the text parser done, but when I use it, the program crashes. Just because of how I test my code, I know the section where it occurs, but I'm not sure what the exact problem is ( no errors or warning, so it's just something I don't see ). Here is the full code
Code: #include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#include <math.h>
[Code].....
I probably made a mistake in the way I allocated memory or tested values, but I'm not sure where it is in my code. Currently it just prints out "Failed to parse data on line 1" then crashes. Here is the text file I give to this program.
Code:
A#3 500 A#3 500 A#3 500
rest 1000
B#4 500 C3 500
So I am trying to write a program that asks the user for a name. If the user enter the right name the program ends but if the user were to enter the wrong name the program would enter a loop prompting the user to re-enter the name. However I am not able to get the program to work!

I'm trying to write this c++ programe:

Using FOR Loop. I know this can be easily done using while loop. But I want to know how to do it with for loop aswell.

I don't see where the problem is.. The program just executes and does nothing.
So I've been turning my programs into classes and I run into errors.
So this program is supposed to allow the user to open the file and either read or write to it.
I've omitted the read part from it as I want to attempt that on my own .

So I'm trying to create a program that allows one to read/write on to output.txt. I though I had everything set up right, but its only writing one word to the text file. Heres the code.

#include <fstream> //needed for ofstream
#include <string> // needed for strings

If I type Puppies Are Cute and go to output.txt, the only thing written in the text file is Puppies.
I'm trying to write a program where it asks the user for a file name.
If that file exists, the it will open the file and then read it and print the information in the file.
However, if the user enters a file name that does not exist, the user will have 2 more tries (for a total of 3 tries) to get the correct name of the file.
I am close to getting it. What I have now just won't go through the loop to validate if the input matches an existing file. It goes straight to the printing of what is in the file. If the file doesn't exist, it prints: "Found your file..Opening..processing...Total keys found = 0."
So, my question, what am I doing wrong that it won't go through the loop properly?
#include<iostream>
#include<iomanip>
#include<fstream>
#include<string>
using namespace std;
int main() {
bool fileFound = false;

I want to create a game that will test the attention and mind flexibility of the user. So the challenge is The user will be given 50 rounds, and each round should generate a random combination of text and words.Then the user must Press 'Y' if the UPPER CASE text spells out a color that match the BACKGROUND. But if the text are in LOWERCASE the user must press 'N'.(Note: you can change the keys to any key from the keyboard if you wish to)
Then I also want my program to record the high score each time the program prompts the user if he/she wishes to play again.
I also want to control the combinations by NOT allowing the text color and background color to be the same.
I also want the combination to generate an AVERAGE of 50% correct combination and 50% wrong combinations. The I want to use is only Red, Blue and Green
HIGH SCORE Determinants:
1. Accuracy ( (Number of corrects / 50 ) * 100% ) - The higher the better.
2. Time in seconds (Time Ended - Time Started) - the lower the better.
Computation for high score: 10 000 * ( (Accuracy) - (2 x total Attempts - Time) )
The output I'm getting here just counts every letter in the sentence and counts them as vowels. I'm trying to make the user defined function return the amount of vowels within the sentence.

I'm new to coding, and I have to write a program to display a class schedule to the user (the classes are entered into the program in strings like this:
Code:
course Calculus3 = {80934,"MATH",11,"Calculus 3","Edward Turner","M,W",950,1100}; )
in the format of an excel file (the user picks the classes they want to have) that then displays the course title and professor in the correct cell corresponding to the day/time the class meets. I've been googling it, and from what I've read, I think I need to use a csv file, but I don't know how to input the data into the file. I know the general format for how data is entered, but I don't know how to write it into a specific file or if I even have to (we covered txt files very briefly in my class, but never touched csv files).
I need to write a program to make the user input some text, and the first letter of each word has to be uppercase. (have to use while loops)
So for example lets say the user inputs:
i lOvE pRoGrAmMiNg
The output needs to be:
I Love Programming
Code: int main()
{
char c, lower_c;
printf("Enter Text");
while (c != '' && c >= 0)
{
if (c >= 'A' && c <= 'Z')
lower_c = c + 32;
else
lower_c = c;

I have started this code by making the letters lowercase (I don't know if this was the right way to approach this, ). I am not sure how proceed after this step, the step of making the first letter uppercase. (PS for the program, loops should be while loops)
int main (){
string filename;
cout << "Enter the file name: ";
cin >> filename;
ofstream myfile( filename.c_str(), ios::app);
}
Here is the code and my original question was how do I make it so that the user can read or write into a file that is not hard coded.
hard code example:
string filename;
cout << "Enter the file name: ";
cin >> filename;
ofstream myfile( "file.txt", ios::app);
Write a program that prompts the user to enter an integer and then displays that integer as a product of its primes and if it is a prime then it should say so? Above is the question I have been given
#include <iostream>
#include <vector>
using namespace std;
int main () {
int num, result;
cout << "Enter A Number " << endl;
system ("pause");
return 0;
}
This is what I have so far, do I have to use a for loop, a while loop or a do loop,
A program which takes input from user and write it to a file then it reads data from that file then it should search for specific data such as email adresses or url etc.
