Oct 24, 2013I am just now in my first programming class for learning C language and I am stuck on one of my homework assignments. I am not asking you to write the code for me or anything because I want to learn by doing it myself but all I am asking for is some pointers to where I am messing up. My program is already finished for what she asked for but I am trying to do an extra credit where she wants us to have the user decide how big the gameboard is and how many mines to hide in it. Really I know that I need to use srand() and rand() but I am not sure how to use them to randomly place mines and without placing mines on top of others.

C++ :: Continue Statement In Nested Loop
Feb 9, 2014I was wondering how I could use a continue statement that continues in a nested loop. For example if I have
for (int i=0;i<amount;i++) {
for (int j=0;j<I[i];j++) {
for (int k=j+1;k<I[i];k++) {
if (P[i][j]+P[i][k]==C[i]) {
//What should be here?
}
}
}
}
If the condition is met then the most outer loop (in i) should continue to the next iteration.
If i simply fill in continue; in before the comment then it only continues the loop in k so that is not what I want.
C :: Y / N Option To Continue - Compiler Does Not Read It As A Loop
Jul 30, 2013I've been having problems with my loop that asks if the user wishes to continue or not. The required input should either be 'y' or 'Y', or 'n' or 'N'. Anything else should be counted as invalid, and repeat the prompt for input. The first few times I ran my program, the compiler does not read it as a loop. The next few times just won't work properly.
Here is the prompt:
Code:
void question() {
char option;
printf("
Do you want to continue? {Y|N) ");
scanf("%c", &option);
[Code] ......
As it is, it immediately runs the else option, but otherwise runs just fine. I suspect it could be because I have not specified a size for the option variable, but I try doing that, and the prompt relegates everything to the else.
(And also, here's the rest of the code. Basically, it just assigns a value to the letters of the word (a/A = 1, b/B = 2, etc.), adds these values, and determines if a word is prime or not based on the sum.)
Code:
#include <stdio.h>
#include <string.h>
#define size 30
int main() {
char letter, word[size], lower, upper, option;
int i, value, ans = 0, a, choice = 1;

C++ :: How To Read / Edit CSV File And Continue From Last Login
May 5, 2014I am working on a program that will do several mathematical calculation and will store the data into a csv file.The one below is just a prototype version of this.In my program,I will store my csv file as (current-date).csv using time.
With this in mind,I want my program to first check does (current-date).csv already exists.If not,the program runs normally and output all the data into the csv file.
However if (current-date).csv already exists,I want my program to read and edit that particular csv file,by skipping part1 in my code(name,id N etc.) and start with prompting the user for numbers straight-away.
In other words, if (current-date).csv already exists,the user should continue outputting the numbers from where the user last left before last termination instead of outputting the name,date & etc into the csv file again.
Eg: if no=22, continue inputting values from no=23 till terminating the program again and storing the values correctly into the csv file.
#include <iostream>
#include <fstream>
#include <iomanip>
#include <locale>
#include <string>
#include <sstream>
#include <time.h>
using namespace std;

If Enter is pressed, the program should then continue to scroll another 3 times and then display the same message above.

C++ :: Tell A Program To Continue Executing Next Line Of Code Within Nested IF Statement?
Nov 25, 2013Is there a way to tell the program to continue reading the next line of code within a nested IF statement?
The reason I want to do this is because the two "else" statements in the following sample (the main and the nested else) will contain the same exact code and I don't want to repeat it twice. I know I can do this by creating a function and calling it from each else statement but I was just wondering if what I'm asking is even possible without using a function.
if(1 < 2) {
// yes 1 is less than 2
if(5 > 10) {
// do something
} else {
// no, 5 in not greater than 10
// here is where I want to tell the program to continue reading the next else statement

C++ :: SDL Key Press Delay
Jan 3, 2014When you press a key it automatically delays a bit then starts repeating without delay.
The second key pressed action comes with a delay and i want it to start repeating without delay. And could not find anything useful.
I might not be able to tell what i want exactly. Ok press simply a key and don't release it in a text editor. You will realize a delay at second character showing up.
C++ :: Stopping Codes With A Key Press
Feb 25, 2013I have a program that I made, which does a list of stuff, then checks if a key is pressed, and if it's pressed, stop the looping.
The problem is, it checks if the key is pressed once a loop, which means that if the list has delays, you have to hold the button down for a while (depending on the list).
Here's an example:
Move mouse;
Pause program for 2 seconds;
Move mouse;
Pause program for 2 seconds;
Check if key is pressed;
What ways can I fix this problem?

View 2 Replies View RelatedC# :: How To Add Keyboard And Button Press To A Program
Apr 13, 2014I have a problem where I need to add the ability to input numbers into a calculator program through either a form button press or keyboard press. I have the button press working fine though I can't seem to get the program to start with the cursor active in the textbox for keyboard input. I've use this.ActiveControl = result; "result" being the textbox. Though the issue here is the program starts off with the cursor active but only for the first instance of keyboard inputs.
Perhaps its the way I wrote the program but is there a way I can achieve this? I found a way to write this calc by having a single event for all button presses, opposed from an event for 1-9. Not sure if this is a good approach but here is some of the code.
private double num = 0;
private string calculate;
bool pressed = false;
private void button_Click(object sender, EventArgs e) {
if ((result.Text == "0")||(pressed == true)) {

C++ :: Detect Arrow Key Press For Linux Only
May 13, 2012I'm trying to implement this on ubuntu, to compile and run only under ubuntu.
I found 100s of other attempts at answering the general question of arrow key press in c++. Nothing solid.
Some recommend using the Readline for the functionality I am trying to implement, but I need to stay clear of GNU licences if I can for this project. And some tips only work on projects for windows machines... for example the conio library.
For linux there may be the option of using the ncurses library which I will take a look at, but I am stubborn and want to implement this myself. It should be an easy straight forward thing to do, which is why I am a bit frustrated at the moment.
Here is my test code so far.
#include <iostream>
#include <sstream>
#include <stdio.h>
#include <string.h>
#include <termios.h>
#include <unistd.h>
using namespace std;
int main(void) {
char a;
stringstream ss;
string s;
[Code] ....
So! This works... 80% of the problem is solved. If you compile this, g++ under linux, ubuntu in my case, and run. Each keystroke reveals the correct key numbers.
q=113
w=119
when I click on the up key I get,
up = 279165
I thought, I can use this number is a if(int == '279165') to detect the up key.
I was not so lucky... this int is not behaving like an int!
So I modified the code to see it I could carry out an int operation on this number.
I added a 100000 to int i.
cout<< i + 100000;
Code:
#include <iostream>
#include <sstream>
#include <stdio.h>
#include <string.h>
#include <termios.h>
#include <unistd.h>
using namespace std;
int main(void) {
char a;
stringstream ss;
string s;
[Code] .....
Compiling and running this, and pressing the UP key gives the following number.
100027100091100065
Some some sort of array, something like, [27][91][65].
I tried all ways to access these individual numbers, actually the third one for comparison purposes, but no luck.
For completeness sake I list the other arrows.
UP = [27][91][65]
DOWN = [27][91][66]
LEFT = [27][91][68]
RIGHT = [27][91][67]
A little further digging shows that these numbers are derived from the representation of a "multi-char" constant, the data type given when pressing special characters...
Now here is the main problem I have, I can find ANY decent documentation on how to handle and play with "multi-char" .

It runs, but it doesn't allow me press space before showing the next line.

C++ :: System (PAUSE) Without Message Or Button Press

cout
cin
cout
cin
...
//
here, I want to have a pause to view what the for loop has come up with but to not have a message display or a button press needed. At the end of the loop, I want it to pause before looping again. IS this possible?
If so, how can I implement it into my program?
