C++ :: Program To Swap Positions Of Digits Of User
Oct 11, 2014
I'm using code blocks ....
1.Write a program to swap positions of digits of a user entered three-digit integer N, where N is equal or between 101 and 999. (i.e. if user enters 389 your program should print 983. If user enters 300 program should print 003). Repeatedly ask user for correct N, if he/she enters an integer N which is not in the range.
2. Given that y= 4*( 1- 1/3 + 1/5- 1/7+ 1/9-...plus or minus 1/N) Write a program using a for-loop or a while-loop to compute and print the sum of first 50 terms of y.
3. a) Write a user-defined function funGx to compute G(x), where
5 if x<-10
x^2 +(5/x) if -10 <=x<-5
x^2 - (5/x-5) if -5<=x<5
x^2 -(5/x) if 5<=x<10
-5 if x>=10
b) Call the user-defined function funGx in main function to compute and print G(x)values for x= -15.5 , x=5, and x= 0.5 in an informative sentence.

I have been trying to finish this code (function) for a while now, but am stuck on the last part. In this code, I prompt the user to select a number of integers and any number of digits and then find the smallest and largest value within these digits. On the next part, I am supposed to determine which of the given digits the smallest and largest are located such that the output should be:
Digit _ can be found in integer number(s): _, _
Here is what I have tried:
Code:
int digitSizeLoca() {
int userNumInteger;
int* iPtr;
int* iPtr2;
int* iPtr3;
int value;
[Code] ....
Seems to do the job, but it always outputs 1, 2...

My problem needs to prompt the user to input an integer and then outputs both the individual digits of the number and the sum of the digits. An example would be entering 8030 and it spits out 8 0 3 0 as well as 8+0+3+0=11 and it needs to work with negative numbers.
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int base;
[Code] ....
Now I don't know if any of this is right a hint my professor gave us is that to get the fourth digit you would do base mod 10 and to get the first digit you do base divided 1000...
Code:
{
int power;
int counter=0;
int value=1;
cout << "Enter the power of 10 you want: ";
[Code] ....

Just wanted to share a program I made. It was the answer to one of the end chapter exercises in the C programming book I'm using, asking the reader to create a program that adds all the digits of an integer.
Code:
/* Program to calculate the sum of the digits in an integer */
#include <stdio.h>
int main () {
int number, right_digit, sum = 0;

I've been working on a program that displays the number of digits in each line of a file, but I feel stuck. Take for example a file that contains these characters:
6347aaa9
54j
811111
6a
709
And I'm trying to display a result like this
1 //that's the number of the line 5 //the number of digits
2 2
3 6
4 1
5 3
Here's what I've written so far:
Code:
#include<stdio.h>
int main() {
char a=0;
int number_of_digits=0, linescount=0, num, number_of_digits_per_line=0;
FILE *inputFile;
if(!(inputFile=fopen("C:TestTest.txt","r")))
[Code]..
I also thought of using fgets and strlen but I am not very good with them and couldn't get the program to work correctly. It did work but it displayed all characters, letters included, not only digits.

c++ program that reads in a sequence of binary digits (values 0 and 1) and stores them into a STL container. The input should terminate on any input that is not a 0 or 1. After finishing the read-process, apply a "bit-stuffing" algorithm to the container. In this case the bit stuffing should occur after four consecutive bits of the same value.i,e. four 0's or four 1's.. Also write the de-stuffing code to process the stuffed data to recreate the original data and verify that the original data is recovered correctly.

Basically this is what i need to do. Write a program that reads a number from the keyboard, separates it into its individual digits and prints the digits to screen, each on its own line followed by the same number of stars as itself.
For example, if the number is 2339 the program should print
9 *********
3 ***
3 ***
2 **
So far i have managed to separate the number and have them on different lines, but how to implement the stars onto each line with the number!
My code so far:
int main() {
int n;
printf("number? ");
scanf("%d", &n);
while (n > 0) {
printf("
%d

I have a fundamental question due to my lack of understanding how arrays work.Let say I have a character array (byte array).
1. do array elements have memory adresses? i guess not but ....
2. if yes is it possible to switch two array positions? For examle:
a[x] change with a[y] for x,y < |a|
as oppose to changing values assigned to individual array positions.

I wrote a program to find the minimum and the maximum values from a vector. It works fine. What I'm trying to do is show the positions of said values and it's not working quite right. When I insert 4 elements: 2 0 1 3 it says:
"The min and max are 0 and 3
The position of the min is: 01
The position of the max is: 03"
What am I doing wrong? Here is the code:
Code:
#include <stdio.h>
#include <conio.h>
int main() {
int A[10], i, j, n, min, max, C[10], k=0, D[10], l=0;
printf("Insert no. of elements in vector A

Question: Write a program that calculates sum of the numbers in the given positions.
Input specification : There will be 4 lines of data. You will be first given the size of the positions array (n). Then, the following line will have n integers which is an ordered list in increasing order and 0 < n ≤ 3000. The third line will give the size of the number array (m) where 0 < m ≤ 5000 and The last line will have m integers between -30000 and 30000.
Note: The positions start from 1 and goes until m.
Output specification : Show one integer number. Sum of the Numbers in the given Positions.
Sample Input I
5
2 5 7 9 10
10
1 8 7 5 17 15 6 7 19 12
Sample Output I
62

For an assignment I have to create a random array of four integers, and then I have to allow someone to input up to ten guesses to guess the array in the correct order. I also need to be able to display whatever was generated by inputting -1. Finally, after every guess I have to tell the inputter how many of the guessed integers are correct and in the correct position, as well as how many integers are correct but not in the correct position.
So far I've been able to get the random array to generate properly, but inputting negative one has no effect, although if I input it four times in a row I get to my 'lose' condition. Also, it only seems to allow the user to input 4 guesses and not 10 before going straight to the 'lose' condition. I need to get these issues sorted out before I can move on to showing how many guesses are right etc....
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main()
{
srand(time (NULL));

i have a problem with a bit of code (part of an as-yet incomplete program that creates a sort of maze with 10 roadblocks, and then finds the shortest route to the exit.
I don't know what it means, to put tags around my code, but I shall try to point out the problem bit clearly. It is not a long segment. This part is all working fine and printing the messages the user needs to see initially:
#include <stdio.h>
#include <stdlib.h>
int main() {
printf("The number -1 shall represent the position of the robot in the matrix.
"
"The number 99 shall represent the position of the exit.
"
"The number 100 shall represent all blocks.
"
"All other numbers represent the number of moves required to reach the occupied space from the robot's position.
");
Below is where is goes bad, and I really am not sure why. The program says it has stopped responding and gets grayed out, and then I get the error message, "An access violation (Segmentation fault) raised in your program.
I have tried using the debugger, and it only tells me it found 0 errors and 0 warnings.
srand(time(NULL));
int initialmatrix [8] [8];
initialmatrix [0] [7] = 99;
int numberofblocks=0;
int randomrow;

I am trying to store values of X and Y into a list like this:
if (pictureBox1.Image != null) {
draw = true;
Graphics g = Graphics.FromImage(imageFile);
Pen pen1 = new Pen(color, 4);
g.DrawRectangle(pen1, e.X - 3, e.Y - 2, 5, 5);
[Code] ....
It stores all the nodes but it stores them as the same position, I am not sure how to make them act independently.

I have the following code segment:
Code:
void Swap(Number& num1, Number& num2)
{
cout<<"Before swap:"<<num1<<" "<<num2<<endl;
Number& temp=num1;
num1=num2;
num2=temp;
cout<<"After swap:"<<num1<<" "<<num2<<endl;
}
[code]...
to which the output is:
Code:
Before swap:13 11
After swap:13 11
13 11 that seems confusing.
why doesn't Swap() swap the two Numbers?

The idea is to make an array and have it sort the contents inside the array in order from smallest to greatest by using a swap function. I don't know why it needs to be done this way when a sort function makes the most sense, but it is what it is.
For simplicity I want my array to only include three numbers. I was thinking {18,-2,24}. My only problem is that I am not understanding how to translate the swap function in an array. I tried using my previous swap function from another assignment and translate it to work for an array, but it doesn't work and I am completely lost and stuck. What I tried to do was this:
#include <iostream>
#include <cstdlib>
using namespace std;
const int SIZE = 3;
double myList[3] = {18, -2, 24};
void swap(myList[0], myList[1], myList[2]) {

writing a sorting function that has an argument for a vector of ints rather than an array; it should use a selection sort algorithm.Here is what I have:
#include <iostream>
#include <vector>
#include <conio.h>
using namespace std;
void fillVector(vector<int> &aVector);
// PRECONDITION: number declared size of array a.
// POSTCONDITION: number_used is the number of values stored in a
//a[0] through a[number_used-1] have been filled with nonnegative int.

I simply need to know how I could swap the first and last letters of the input in this program:
int main() {
cout << "---------------------------------------------------------" << endl;
cout << " Letter Swapping Program" << endl;
cout << "---------------------------------------------------------" << endl;
string word;
cout << "Please enter a word at least 3 letters long: ";
cin >> word;
[Code] ....
By all means, I know this is a messy program and is not the most concise way to write it....
