C++ :: How To Get Larger 2 Out Of 3 Integers
Mar 12, 2014How to write a simple function that will take 3 ints and find the sum of the higher 2? This is what i got so far:
int findsum(int a,int b,int c)// will find the highest int and return it to our main program {
int max,max2;// this sets our local variable max
// next we will find the larger of our first 2 variables
if( a>=b)
{ max=a;

C++ :: Converting Console App To Larger GUI Based App
Oct 12, 2012We never got into any gui stuff. It was strictly console apps. That being said I have been able to create a few small apps. I would like to start to create GUI based apps but I am kind of overwhelmed at the choices. I dont know where to go from here. Since I have c++ experience I would think Visual C++ would be the choice but i have been reading a lot of forums and getting other info.
Is there another language I should look at the would allow me to convert my program quicker or easier?
The console program I already created is very very simple and want to make a gui for.
Quick break down.
Reads file
Changes file contents based on search string,
saves and closes file
and kills a windows service
exits
Only thing I want to add would be the ability to run the file from a remote site within the company LAN(not a priority though). Currently it needs to be run locally on the server.
C :: Fscanf - Segmentation Fault For Larger Project
Apr 19, 2013I added this snippet of code to a larger project I use to read some numbers in from a file, but for some reason I'm getting a segmentation fault.
Code:
printf("starting main
");
FILE *cutoffs;
double cut1=0, cut2=0, cut3=0;
printf("trying to open file
The cutoffs.in file looks something like
Code: 3.475 3.875 4.025
I ran the gdb debugger, so I know it is occurring at that fscanf; however, it doesn't give any other details (to be honest I don't have much experience with debuggers :x) ..The values are being put into an array. Before I just had numbers initialized in the array by hand, but need to have 20 different runs of this code with different numbers each time...
C++ :: Sort Huge Files (larger Than Available Memory)
May 30, 2012I am trying to understand what techiques can be used to sort really huge files (larger than available memory). I did some googling and came across one technique.
1. Are there any better ways to get this done?
2. Is there some tweaking that can be done to make this itself better?
Large enough so that you get a lot of records, but small enough such that it will comfortably fit into memory
3. How do you decide on this value? Consider, memory is 4 GB and currently about 2GB is consumed, and file to sort is 10GB in size. (Consumed memory could of course change dynamically during execution - consumed more/less by other apps.)
C++ :: Size Of Process Grows Larger For Lots Of Small Memory Allocations
Jun 21, 2013Why the size of a process grows larger in size for lots of small memory allocations. For example, say I have this struct, which is 16 bytes (for a 32 bit build):
Code:
struct Person {
int iID;
int iAge;
char * pForeName;
char * pSurName;
};
If I allocate memory like this:
Code:
LPBYTE lpB = new BYTE[sizeof(Person) * 1000000];
Then my process grows to 16,48KB in size, which is what I expected. However if I allocate memory like this:
Code:
Person * lpPerson;
for(int i = 0; i < 1000000; ++i)
lpPerson = new Person;
Then the process grows to 78,656KB, which I don't understand.
Additionally, I was surprised to find a vector acts more similarly to the first example. This code:
Code:
Person temp = { 0 };
std::vector<Person> people;
for(int i = 0; i < 1000000; ++i)
people.push_back(temp);
Only increases the process memory to 16,892.
C :: Function To Round A Number To Give Integer Number That Is Closer To Real Value
Oct 9, 2013I was told to use a round function to round a number to give an integer number that is closer to the real value. (for example if the number is 114.67 I need to print an int value of 115 instead of 114)
I am not exactly sure how a round function works, but I am told to include math.h library. What I try doesn't seem to work.

Jul 31, 2013How can I concatenate two 2-dimensional int arrays into one larger 3-dimensional array. This question is also valid for the 3-dimensional vectors. I know the command for the one dimensional vector as:
std::vector<int> results;
results.reserve(arr1.size() + arr2.size());
results.insert(results.end(), arr1.begin(), arr1.end());
results.insert(results.end(), arr2.begin(), arr2.end());
and for the one dimensional array as:
int * result = new int[size1 + size2];
copy(arr1, arr1 + size1, result);
copy(arr2, arr2 + size2, result + size1);
But I do not know how to make a 3-dimensional array or vector.
C :: Why Size Of Struct Is Larger Than Sum Of All Size Of Its Members
Jul 11, 2013I was wondering why, in C, the sizeof of a struct is larger than the the sum of all the sizeofs of it's members. It only seems to be by a few bytes, but as a bit of a perfectionist I fine this a bit annoying.

C/C++ :: Reading Number In CPP Program With Scanf
May 17, 2014I'm using scanf() function to read numbers in my cpp program and, for example, if i want to read a string that is a complete name i could use

or if i want to read only vogals i could use
scanf("%[aeiou]", x);
Is it possible to read only positive numbers or only negatives numbers using scanf() and how to do it?
C/C++ :: Program To Print Out Binary Value Of 16 Bit Number
Sep 22, 2013Write a program to print out the binary value of a 16 bit number.
Create integers i, count, and mask.
Set 'i' to a hex value of 0x1b53.
Set mask to a value of 0x8000. Why?
print a line to show the hex value of i and then the leader for the binary value like this: Hex value = 1b53 Binary=
Use a for loop to loop 16 times and print 16 digits, using count as the loop counter
To test for each digit value, bitwise and 'i' with 'mask'
when the result for the bitwise and is true, print the number '1'
when the result for the bitwise and is false, print the number '0'
then shift mask one place to the right
print a new line and then quit
Use prtscrn and make a hard copy of the code with the console output.
Extra: use the modulus of count and print a space after every 4th digit to make the binary easier to read
The output should look like this: Hex value = 1b53, Binary= 0001 1011 0101 0011
so far this is what i have
#include <stdio.h>
#include <stdlib.h>
int main() {
int i, count, mask;
// 1B53 0001 1011 0101 0011
// 8000 1000 0000 0000 0000
i = 0x1b53;

it is telling me that there is an "else" without previous "if", also is the program that I wrote correct?
