I am trying to write a program which reads a string and prints the reversal of that string. My main problem, is the fact that I need to type my input to be reverse twice, and only reads at the second time.
Here follows my code :
#include <stdio.h>
#define N 100
int main(){
char array[N], *pointer;
int x = 0;
printf("Enter a message: ");
[Code] ....
It's a tic-tac-toe program. I haven't finished doing everything I need to for the project, I'm just trying to get certain parts working as I go.
Anyway, my problem: The program will print the board and ask the first player which square they want to mark. Then it will print the updated board, print the question for the second player to input their square choice but not actually stop to let the user enter anything. Instead it prints the board again and then prints the question for player one again -- this time stopping to let them type in their choice.
Here's my code:
#include <stdio.h>
// Function prototypes
void printBoard(char board[3][3]);
int main() {
int quit = 0;
// Loop so game continues until player quits
[Code] .....
And it looks like this when I run it, as an example:
-------------
| 1 | 2 | 3 |
-------------
| 4 | 5 | 6 |
-------------
| 7 | 8 | 9 |
-------------
Player 'C' enter a square: 5
-------------
| 1 | 2 | 3 |
-------------
| 4 | C | 6 |
-------------
| 7 | 8 | 9 |
-------------
Player 'U' enter a square:
-------------
| 1 | 2 | 3 |
-------------
| 4 | C | 6 |
-------------
| 7 | 8 | 9 |
-------------
Player 'C' enter a square:
I have a lab with the following instructions:
Manually create an input text file called Lab22BInput.txt with the following data:
Dove
Doe
Alston
Zebra
Egg
Write a program that will read the names from the input file. Print out each of the names read to the screen. The program should go through the list of names and determine which comes 1st in the alphabet. The program should determine how many letters are in this name. Print out the name that comes first in the alphabet and the length of the name.
I have created the input file, and the data correctly outputs to the screen when I run the program. However, I do not know what kind of logic to use to sort them alphabetically and determine the amounts of characters.
So far I have the following:
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
string str1, str2, str3, str4, str5;

The question is "Write a program that uses a while loop to read a set of integers from an input file called "data.txt" and prints the total number of even numbers read from the file."
Code below is the program I have created so far. I keep getting the window to pop up but not stay up so I am assuming I am doing something wrong.
#include <iostream>
#include <fstream>
using namespace std;
int main() {
std::fstream input("data.txt");
if (!input.is_open()) {
std::cout << "There was an error opening data.txt";

I am trying to reverse a Linked list using recursion but whenever I try to print it after reversal it prints only the last element of the list.
Code:
void reverseRecursive(Node **root, Node *temp)
{
Node *next = temp->next;
if(temp->next == NULL)
{
*root = temp;
[Code]...
I have just posted the reverse function to enable easy readability rather than post the entire code
it will not run and im not sure why. I have a couple of errors, but I'm not sure why.
Here is my code.

I want to be able to read 2 line input, then safe them in separate arrays.
line1 input=array1

//struct CityBlock
//{
// bool Blocked;
// bool N_Blocked;
// bool FireStation;

Here's my code, it's for a poker hand evaluator
input:
'ad 2d 3d 4d 5d...
...4s 5s 6s 7s 8s'
I think it should go through all the 10 crads and disply the name of each card, but it seems to only do it for the second hand
Code:
include <stdio.h>
#include <ctype.h>
int main( void ) {
char inputtedhand[64];
int z=0, counter=0;
int index;
int i=0,m=0,n=0;
[Code].....
I've got a program to read the input file as records. The problem is all it does is cout Record Number etc but it doesn't grab the data.
#include <fstream>
#include <string>
#include <iostream>
using namespace std;
int main() {
const int RANGE = 12;
string tab[RANGE];
[Code] .....
Essentially the problem is that when I click the mouse, the program doesn't seem to record the coordinates. So the if statements are never executed. The problem could also be with the if statements, I'm not sure.
One thing I noticed was that when the do while loop is running and the left mouse button is not pressed then X and Y of dwMousePosition are both 0. But then if I press the left mouse button then the coordinates become x = 1 and y = 0.
NOTE I'm on Windows 7, 64 bit, using Visual Studio Express 2013 for Windows Desktop
#include <iostream>
#include <windows.h>
#include <string>
#include <new>
#include <stdio.h>
using namespace std;
INPUT_RECORD ir[128];
DWORD nRead;
[Code] .....
So running the following code
Code:
#include <stdio.h>
int main(void) {
char c;
int i=1;
while (scanf("%c", &c)==1)
printf("loop sequence %i: %c(%i)
[Code] ......
Done it seems a "carriage return" serves two purposes here, one is to signal the program to read in the character typed in before the "carriage return", another serves as a second character typed, how can i do this cleanly, that is without having to use a "carriage return" as the second character to signal "I've typed in the first character already".
I'm new to C/C++. I am attemping to use fgets and sscanf to read a line of input, and confirm it is a positive number.My code works great, except for the case of a negative number. When I enter a negative number, my while loop seems to run infinitely, with stdin providng the same input over and over again.
Here's the code snippet:
Code:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#define TEXT_LEN 64
void foo() {
char* inStr = (char*)malloc(sizeof(char)*TEXT_LEN);
memset(inStr, 0, TEXT_LEN);
}
[code]....
So I have to write a code for my C++ class, and I am having a problem trying to figure out how to get my code to read multiple int values. This is what my code should look like
Enter two times in military format (e.g., 1730 1520): 1730 1520
[1520<1730]
Enter two times in military format (e.g., 1730 1520): 1520 1730
[1520<1730]
Enter two times in military format (e.g., 1730 1520): 1730 1730
[1730==1730]
Enter two times in military format (e.g., 1730 1520): 1760 1520
1760: [INVALID TIME 1]
Enter two times in military format (e.g., 1730 1520): twelve 2
[INVALID NUMERIC INPUT]

how to read characters from user and construct a sting and then extract part of it using substring?
View 2 Replies View RelatedI'm very new to c programming and I have some background in C# and java. I am supposed to read a string from input then determine in that string, which character is the largest, i.e. I think b>e and e>z, e.t.c. If the string is empty I should return ' '.
I haven't done any programming in C before and I don't know how to handle strings and characters in C.
The problem states that i need to accept any pin number between "00000" and "99999". I need to read the PIN the user enters as an integer. The problem is that if the PIN is read as an integer, the PIN "01111" will be "1111" which is invalid and the pin "00001" would be read as "1" which is also invalid. How would I go about fixing this problem for PIN numbers that start with a "0"? Again I cannot read the PIN as a char array or string.

My program is designed to read input from the user and then store that input in a structure variable. Whenever i use the cin.getline() function, it comes up with a semantic issue. Here is the code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
const int DESCRIPTION_SIZE = 100, DATE_SIZE = 20;
struct inventory {
string description[DESCRIPTION_SIZE];

I left out the other functions. The error reads "no matching member function for call to 'getline'.
I'm having a problem with the two while statements in my UDF.
- 1. It will run both while loops twice...?

I'm trying to code a program to read the user's input and have it:
-count vowels
-stop counting vowels after '.' or '?' (ie. abcdjwef is 1 a, 1 e; while fje.fwdfeiii is just 1 e)
-closes when ENTER is pressed after a '.' or '?' is found (ie. closes after 'abacds. ENTER' as well as 'as.fefsdf ENTER')
-display the number of vowels
Is there any way to do this with only 'cin >> userInput' and a while loop checking for punctuation?
Write code to do the following:
1) declare a variable ptr as a pointer to int and initialize it to NULL
2) dynamically allocate memory for an array of 100 elements
3) read 100 elements from the standard input device and store them in the array.
This is what I have so far, I'd like to know if its ok or if something is wrong.
int *ptr = NULL;
ptr = new int[100];
cin >> dataPtr [arr];
