I have to make a 8-puzzle and I got the algorithm i just dont know how to restart the program every time i type the move of the blank place in the 3x3 puzzle so i dont have to make 10000 lines to solve the puzzle
View 2 RepliesI am trying to place a counter to count in each time a new order comes in, but I am having trouble with the memory allocation part.
I allocate memory to take in names each time an order comes through, but when I print out the names, I get 0x100103ae0....
I just started learning c++ and got a problem now, i need a Y/N code, i case of yes the loop will restart and i case of no the program will end, Heres the code i got so far from trying to make my first steps.
#include <stdio.h>
void main() {
int a,b,c;
printf ("Zahl 1 Eingeben
");
scanf ("%i",&a);
[Code] ....
As u can see the other printf tasks are in german, but they are not important, the last one needs a Y/N "switch" y to restart the loop, and n to stop the program.
I've just started to learn C programming. In following program I need to use a loop, so at the end, it asks the user that if wants to try other numbers or not. If yes program restarts from beginning.
Code:
/*
A program who checks three positive integers to be 3 sides of a triangle and calculates the area and shows the triangle type.

#define _CRT_SECURE_NO_WARNINGS

int main(void)

I have a question about my program.. I would like to make a program that if you put "ABC" on INT, the program will restart again... below are my coding...but it not works..if i put ABC on INT, the "Invalid Mark.. please re-insert mark :" will repeat, repeat and repeat infinitely...
Code:
#include <stdio.h>
void calcul() {int mark;
char * grade;
if (!(scanf("%d",&mark))){printf("

My program does compile and counts the number of lines of code, which is LOC: 20. My issue this, according to my code instruction it should not count comments (//) and also shouldn't count blank lines of code. Unfortunately my code is counting // and white space.
What seems to be working is #, all three includes are not being counted. That’s a good sign. I’m using the same technique not to count #. Why isn't working for comments and blank lines? I’m pretty sure that my logic is correct. I think my problem is maybe syntax.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
//read my file

I'm making some progress. My program does compile and output the number of line per code, but it shouldn't count comments and blank lines. I tried using (s.substr(0,2) == "//") as suggested but it didn't work.
This is my improved code:
Code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
const int A = 3;
int main() {
string s;

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;

After I enter in the 8 digit account number the program just stops and I can't find where the logical error is

bool validateDigit(string);
void calculateA(string);

My objectives for this program is to open and read a file "dict.txt" which has the following data:
4
dog
pepper
marker
teapot
It needs to rotate the inner letters one to the right so you'd end up with "mrkear" etc, and then write those words into a new file "scramble.txt" one per line.I'm having a lot of problems understanding the program. Compiling is giving me a lot of warnings/errors.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAXW 10 //max number of words in file
#define MAXS 81 //max size of string
}

CompileTimeChecker(...);

How can I take a variable value and put it in a DataBase to recover the value after a restart?
View 4 Replies View RelatedI have a simple game loop.
while(true) {
//round initialization stuff
while(true) {
//capture input, make pieces move,
}
}
I am faced with the decision of what is the best way of restarting the game. The problem is, the condition for restarting a game is very, very deep inside the game's logic. So returning returning... is not an option, or at least, it ain't gonna be pretty.
So one of my considerations is to use a goto label, like so:
while(true) {
//round initialization stuff
while(true) {
//capture input, make pieces move,
} restart_round:
}
This seems to be the cleanest solution, since it allows me to fully reset the 'state' of the round, by first having all the destructors(pertaining to the round's objects) called, and then the constructors and other initialisation stuff.
Are there any subtleties that I am missing regarding this solution?
i writing a code which will calculate the difference between time_in and time out. Can i use a 2 dimensional array for example
int time_in[hours][minutes]
int time_out[hours[minutes]
I am an IT college student and this is a self-assigned project i have done in an attempt to learn programming in C AND at the same time how time scheduling of an OS works (Both done in order to prepare for upcoming semester exams) using FCFS ,SJF, RR and PS algorithms (planning on adding SRT too sometime soon). (took me 9 hours total work time including validations). What i wanna know is from more seasoned coders if i am on the right track. *cross fingers*

#include <stdio.h>

#define P_Q 1000

I'm trying to display the AM/PM on my program:
Also is there a way to display the time only instead of the date? How will i change the program to display the time in standard 12 hours, instead of 24 hours?
#include <iostream>
#include <time.h>
using namespace std;
int main()
{
time_t tim;
time(&tim);
cout << ctime(&tim);
}
I'm challenged to write a program which calculates the time difference between two daytime.
compiler doesn't give an error, yet the warning: "format '%d' expects argument of type 'int *', but argument 3 has type 'int' [- Wformat]" for lines 24 and 26
However, by entering the first time the program crashes anyway. so I assume I do really need some pointer to make it read from the console can you see where my problem is?

#include <stdio.h>
#include <stdlib.h>
typedef struct {
int Second;
int Minute;
int Hour;
}Time;

I have a weird problem, my computer restarts imidiately after program writen in dev-cpp is compiled AND run. When I run any program, it lasts about 1 second, then program closes, and computer reboots. It doesn't matter whether program is writen now or earlier, my dev-cpp version is 4.9.9.2. Source code can be as simple as this:
#include <iostream>
#include <conio.h>
using namespace std;
int main() {
getch();
return 0;
}
and it restarts anyway...
Say I want to leave a program running and it stops when I press F9 for instance, I'm looking for something like (and note this is just a generalization).
#include blah
using namespace std;
/wait 2 hours
/key.press = F9
return 0;
I am trying to create a program that calculates fraction of time remaining when a student leaves during the middle of the semester. I have to use function files here. I am having trouble with the division in function long double tuitionfrac(int, int, int). No matter what numbers are entered, fractime gives an output of 0. I don't understand that.
long double tuitionfrac(int opening, int leaving, int semend)
{
int lefttime = semend - leaving;
cout << "Left time " << lefttime << endl; //for error checking
int tottime = semend - opening + 1;
cout << "Total time " << tottime << endl;
long double fractime = lefttime/tottime;
cout << "fractional time " << fractime << endl; //always returns as 0.
return fractime;
}
I want to know if there is a function or library that starts counting time when the program starts. Because I'm making a program that is dependent on time.
Pseudo code
time starts
if ( seconds % 2 == 0 ) {
counter++;
}
I was browsing the web looking for simple yet fun programming challenges and crossed this one. I figured out how to reverse the string in place but I want it to read "blue is house the". I approached it in two ways for the heck of it. My idea was the second one, the first one I googled. I didn't know a simple rbegin() could do that, pretty neat.
I found the question here.[URL] ....
Code:
#include <iostream>
#include <string>
int main(int argc, const char * argv[])

Prototype should be something like

I have tried my best to write, but all tries ended in inf loops and reading invalid locations of array.
