C :: Read In N / Then N Words And Check To See If First Word Is Repeated

Sep 23, 2013

Read in n, then n lastnames, and check to see if the first in the list is ever repeated again.Here's what I have so far:

Code:

#include <stdio.h>
#include <stdlib.h>
int strcmp(char *w1, char *w2);
int main() {
int j, n;
char string1[30], string2[30];
}

[code]....

I see the problem is that it lies within n amount of string that I am not going through every string to compare to the first one.How will do compare every string to the first one?

Current output:
3
alex
alex
alex
Not repeated

3
alex
ash
peter
Not repeated

C :: Read Contents Of A File Using Low I/O Read Statements

May 15, 2013

I want to read the contents of a file block (512 bytes) by block using low I/O read statements. Each record is 64 bytes long and has a pre-defined structure. The first 4 bytes are an unsigned integer; the next 20 bytes are ascii text, etc.

I have a buffer which I can access with buf[0] to buf[63] to read the first record and then buf[64] to buf[127] for the second, etc. However, I was wondering how to map a record so that I can refer to an integer as an integer and a float as float, etc. I can't create a struct and move the 64 bytes to it, as I will have alllignment/padding problems.

What is the standard way to deal with records in C?

C++ :: SDL - Check For A Key That Is Hold Down?

Sep 13, 2013

I'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, 2013

I 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, 2014

I'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, 2013

I'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?

C :: Check Addresses On Equality Possible?

Sep 18, 2014

I 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, 2015

I'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):
}

C++ :: How To Check If A Vector Contains Garbage

Jan 29, 2015

So 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?
