C :: Loop Does Not Work And Program Quits Without Displaying For Loop Function
Oct 13, 2014We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.

Feb 15, 2015I have tried to submit this topic before but i didn't submit my whole code and it was removed. So here it is. All I am trying to do is load form2 from form1 then back to form1 from form2 for a certain number of times the get out of the loop. I am new to C-Sharp and it seems as though I cant seem to figure out a way to do this.
Here is form1 and form2 code. I have commented out a few things I have tried.

C++ :: SDL - Check For A Key That Is Hold Down?
Sep 13, 2013I'm using SDL to try to create a Run and Shoot game. But I do not know how to check if a key is down while the user is HOLDING it.
I do know how to check if a key was pressed.
I have tried with the "event.key.keysym.sym" and "Uint8 *keystate = GetKeyState(NULL)" both worked to check if a key was down but I thought that the GetKeyState(); Function would even check when a key where HELD down
I want my player to move while holding down left or right arrow. So I did something like:
Code:
Uint8 *keystate = GetKeyState(NULL);
if (keystate[SDLK_RIGHT]) {
apply_surface(x++, y, player, screen);
}
How to check if a key is held down?
C++ :: How To Check Which Variable Has No Value
Nov 12, 2013I am writing a console program for a class. I have satisfied the assignment, but I want to clear up what is mostly a cosmetic problem. The program prints a form to the console and places the cursor at a location on the form where the user inputs data. The problem occurs when the user presses the enter key without entering data. The cursor goes to the beginning of the next line. If the user enters data after this, the program functions correctly. I want to know how I can reposition the cursor if the user enters no data.
This is the code that reads one of the values:
Code:
void getHousing(HANDLE screen, MonthlyBudget &inputBudget) {
placeCursor(screen, HOUSING_ROW, ACTUAL_COL);
cin >> inputBudget.housing;
while (!validateEntry(screen, inputBudget.housing)) {
placeCursor(screen, HOUSING_ROW, ACTUAL_COL);
cout << SEVEN_SPACES << endl;
placeCursor(screen, HOUSING_ROW, ACTUAL_COL);
cin >> inputBudget.housing;
}
}
validateEntry checks that the entered value is >= 0 SEVEN_SPACES is a string of seven spaces to cover up the previous entry.
C++ :: How To Check For EOF Without Getline
Mar 16, 2014I'm currently trying to write a while loop that checks if the text file has read all the contents inside. I've tried using
while(!in.eof())
but as usual it executes my loop an extra iteration, printing my last output twice. I am reading my data in from a method inside a class, so I cannot use getline as my while test to check if the file has read input or not. Is there any way to force my loop to check if the end of file has been read before the eof() test is executed?
C++ :: How To Check What Causes A Stack Overflow
Sep 22, 2013I'm getting a stack overflow error because for large numbers, this code I'm working on allocates too much on the stack.
Is there a way of tracking stack allocations specifically?
Will multithreading solve my problem if each thread is doing the static allocations?
Would I really have to use malloc or new every time I wanted to use memory just to make my code scale to huge numbers?

Sep 18, 2014I was wondering if it is possible to check if two addresses, so pointers are equal.I was saving the address of an array, and later wanted to identify it by the address, so if my area has the address: int *my_array; // is equal to: 0x1e9aa3a2c ...Later when I go through a list of pointers like:
list=
0x1e9c7e060
0x1e9ba6640
0x1e9aa3a2c <== my address
0x1e9aa3a2c
I want the third one to be equal to my list, but with == it didn't work for me.
C :: How To Check Dates In Programming
Mar 6, 2015I'm supposed to make a program that can tell which date, out of any number of dates entered by the user, is the earliest date. However, this is based off another program that I did not do in the last chapter. Since it's a pretty simple program to use as the base for the more "generalized" one, I decided to make the more basic one that can only take two dates, first. If it was just one integer, I could just use date1 for the first date and date2 for the second date, but each date uses 6-8 separate numbers.
how do I tell it something like, "if(date1 < date2)", with date1 and date2 including their month, day, and year. I could do a separate integer name/tag (I forgot what they're called) for each number, but that sounds like doing a lot more adding and subtracting, and like it could easily get messy.Should I, or can I, add all the numbers under the "date" together to see which date has the "lowest number" or "earliest date", or should I somehow handle each number, that is month, day, and year, separately?Here's the code so far:
Code:
include <stdio.h>int main(void)
{
int date1, date2;
printf("Enter first date (mm/dd/yy):
");
scanf("%d/%d/%d", &date1);
printf("Enter second date (mm/dd/yy):
}

View 8 Replies View RelatedC++ :: How To Check If A Vector Contains Garbage
Jan 29, 2015So i have this code:
if (get_brick_at(Position(row, column)) == NULL)
Where get_brick_at is defined like this:
>Brick& get_brick_at(const Position & p) {
return board[p.get_row()][p.get_column()];
}
Now, of course this does not work since the compiler cannot convert from long int to a Position. So how do i know if the return value of get_brick_at is garbage?
I also have a couple of other situations where i want to return some kind of NULL-like value under certain circumstances.
My question is: How do i handle situations like that?
C++ :: Check CPU / RAM USAGE / Temperature
Nov 1, 2014I want to make an application that will check CPU/RAM USAGE and CPU TEMPERATURE and if it meets some requirements it will restart your system or do something else..but my problem is:
1) How do i get that info? (i know that in VB.net there is an easy way) but in C/C++ or Java?
2) Is it possible though a C program to execute a command and parse that info to your program?
I am mainly interested for windows but i need also info for linux too..
C++ :: Check For Clicks Within Object

void EGame::OnLButtonDown(int mX, int mY) {
int ID = mX / 200;
ID = ID + ((mY / 200) * 3);
if(grid[ID] != GRID_TYPE_NONE) {

Using the width and height of the object, e.g; pX->w is width and pX->h is height ....
How would I check within the 200x200 area with mX and mY?

C++ :: How To Check If Input Is Integer
Jan 15, 2013I have an assignment to do..i have done it..but i need to do one more thing. Things sound like this: user inputs 6 integers program needs to check them if there are integer if not it has to output a message for the user if the input is integer it has to go further and work with the input. I have used this structure :
if ( ! ( cin >> temp ) ) {
cout<<"Input is not integer.This program will end ! "<<endl<<endl<<endl;
system("pause");
return 0;
}
Where I declared temp as being int since i started, the problem is after it gets the last input still waits for an input i will attach the source code if needed.
