C :: File Attribute Modification Program Not Working
Mar 27, 2013
I would like to modify attributes like modification/creation dates.The function is correctly working as if I type in "ls -al", the timestamp is correct. But when using my program to read these attributes, it returns the "real" modification/creation date. Here is the function that shows the timestamp :
Code:
time_t t = sb.st_mtime; struct tm tm = *localtime (&t);
char s[32];
strftime (s, sizeof s, "%d/%m/%Y %H:%M:%S", &tm);
printf ("%-14s %s", lecture->d_name, s); And here is the code for modifying the timestamps : Code: void modifyAttributes(char * file, int mtime, int atime)
}
I am having trouble with recursively modifying a <string, int> map (NCPB) -- when I call for what should be existing values in the map, I get "junk" values back (integers, but sometimes negative, large numbers, etc.). I've posted only the problematic function here:
int Count_Noncrossing(string RNA, map<string, int> &NCPB) { map <string, int>::iterator it; if (RNA.length() <= 2)//perfect short interval can only have 1 match; return 1 { return 1;
[Code] ....
The problem is that when I ask for existing map values in a subsequent recursive call, they don't seem to be there. I imagine I'm missing something straightforward but can't seem to find it. I've tried declaring the map globally, passing it (as shown above), nothing seems to work.
I have tried googling, so, reddit, irc, and various other forums. Anyways, I am writing a todo list app in c. It generates an xml tree that looks something like this: [URL]... . The problem where I am struggling, is in the function todo_complete, I try to make the attribute of an item switch from false to true. it does it without error, but I can't make it stay that way. here is the code: [URL]...
no instance of overloaded function "std::vector<_Ty, _Alloc>::push_back [with _Ty=std::pair<std::regex, std::string>, _Alloc=std::allocator<std::pair<std::regex, std::string>>]" matches the argument list argument types are: (std::pair<const char *, const char *>) object type is: std::vector<std::pair<std::regex, std::string>, std::allocator<std::pair<std::regex, std::string>>>
I am trying to create a custom ValidationAttribute in my c# .net code. I have done a lot of searching and have code that should be working but the IsValid method is not firing as far as I can tell.
Model code:
[Required(AllowEmptyStrings = false, ErrorMessage = "required")] //[Range(2014, 2100, ErrorMessage="Please enter a valid year.")] //[RegularExpression(@"^d{4}$", ErrorMessage = "Please enter a valid year.")] [ValidYear(ErrorMessage="Please enter one >= 2014")] [Display(Name = "Exp. Year")] public string expYear { get; set; }
And this is the class in that same model:
public class ValidYearAttribute : ValidationAttribute { protected override ValidationResult IsValid(object value, ValidationContext validationContext){ return new ValidationResult("Something went wrong"); } }
I'm a bit stuck on a program that prints out a 8x8 chessboard and Q to represent queens where the user enters input. The intended output is: Code: Enter the columns containing queens, in order by row: 0 3 4 0 0 7 6 7
I am relatively new to C programming, and I am encountering numerous issues with this program that I cant seem to figure out how to fix.
First, when the user selects the arithmetic game, I keep on getting different incorrect answers from the arithgame function. For example, when I am presented with the question 3+2=_, sometimes the function claims the answer is the first number, 3, and other times the function gives me a multiplication answer, 6. This happens in both the addition and multiplication parts (ie. the multiplication answer will either be the first number or the addition answer).
Additionally, I cant figure out why my guessing game loops forever, rather than letting me guess until I get a correct answer.
I'm having troubles with this program I made. Put it simply, it's a basic program using Queues. Whenever I try to input a value, my compiler(Dev C) suddenly stops working. The .exe file crashes and I've no way on how I can execute my program.
Code : #include<iostream> using namespace std; int *queue; int rear, front, queueSize; void enqueue(); void dequeue(); void display();
I'm not sure what I'm missing. It is supposed to input and display player's name and score, calculate the average score, and display the players who scored below average.
It simply doesn't work. All I get is a black screen. Debug spits out an exit code of 1073741510 (0xc000013a).
Code: #include <iostream> #include <string> #include <iomanip> using namespace std;
const int arSize = 100; int inputPlayerData (string playerName [], int playerScore [], int &numPlayers);
I'm trying to write a C++ program that will allow a user to input a number from the keyboard. Then using a loop, that will perform 10 times, multiply the entered number by the loop counter. Print out the loop counter, the entered number and the product of the loop counter and the entered number. A one-time heading should be displayed before information is printed.
This kinda of what I have so far:
#include <iosteam> using namespace std; int main () { Start Declare: numScores, sum, score, avg, SENTINEL = 200 numScores = 0
[Code] ....
All the programs I have tried to make are not working?
I tested my count funtion. So my count function is not working properly, it should return 5 because 5 words have prefix "tal," but it is giving me 10. It's counting blank nodes.
This is my main.cpp file
int main() { string word; cout<<"Enter a word"<<endl; cin >> word; string filename;
I need to append file path for some particular program. But the problem is when I append it like below, it gets error whether filepath seems to be C:/Users/My/Desktop/C++/1.txt
int i=1; stringstream str; str<<"C:/Users/My/Desktop/C++/"<<i<<".txt"; string filepath=str.str(); cout<<filepath; ifstream ipf(filepath); if(ipf) { do some thing...}
But if it was like this no error, program work as desired.
int i=1; stringstream str; str<<"C:/Users/My/Desktop/C++/"<<i<<".txt"; string filepath=str.str(); cout<<filepath; ifstream ipf("C:/Users/My/Desktop/C++/1.txt"); if(ipf) { do some thing...}
i need my code to stop outputting all the numbers throughout the steps it is going through i just need it to output the total
this is my input M C C C L I V
and its output is
Your total is 1000 Your total is 1100 Your total is 1200 Your total is 1300 your total is 1350 Your total is 1351
i just need it to output the last number
// write a program to read a string of characters // that represent a Roman numberal and then convert // to Arabic form ( an integer // input from data file
Here your supposed to create a program that takes in information and formats it into three columns.
I can't seem to use the float variable unitprice with decimal places here for, if I try to use %.1f and type in an input, the program seems to skip over the second scanf function, not allowing me to put input into the third scanf function as the program runs before I can.
I can use %f on its own and it works but this creates too many zeroes(and you're supposed to set the currency limit to $99999.99).
Code: #include <stdio.h> int main(void) { int itemno, month, year, day; float unitprice;
[Code]....
So the output should look like three columns. It's just the float that is the issue here....
I am trying to take text from a file and have it displayed using fprintf at line 46. When I run the below code nothing prints out. My text file has 4 lines with 5 different strings separated by whitespace.
#include <cstdlib> #include <vector> #include <cstring> #include <stdlib.h> #include <errno.h> #include <stdio.h> using namespace std; //declare my own struct
i have turbo c++ 3.0 installed . my program is compiled without error and is running. but when i choose option to display scores in the consol , it hangs . check my code. i have to run this on same compiler. i just want to display all the contenets of text file .
