for example having input "12345556asf87" we get "123456asf". I need to do this task with getchar and putchar, and the with strings. My programs aren't working
stream:
char c = 0, c_ = 0;
char flag = 0;
while ((c = getchar()) != '.')
{
[Code]....
That is sequence "aasdf123456785fg87" will be transformed into "aasdf12345678fg". I need to do this task in two variants: at once using getchar and putchar and then with strings. The object is done, but I think it could be done more easier. My codes:
(1)
char flag = 0;
while ((c = getchar()) != '.')
{
if (isdigit(c))

why its not reading my for loop for rows its only doing columns ...
i want to print Largest number from any 5 rows.Th number printed should be any one of the largest in the five rows of 2d arrays.I have created code for largest number in each row but how to pick and print them randomly?.
Code:
#include<conio.h>
main( )
{
int a,b,c,d,e,x;
int arr[] = {a,b,c,d,e};
int Matrix[5][5] ={ /*Initializing array*/
2,4,3,5,9,
6,8,2,2,10,
[Code]...
I'm working on a program in C++ that is supposed to read in a file, store the content of the file into a 2D array, assign characters to each of the numbers in the array and store in a char array, and print both of these arrays. It's then supposed to go through the initial array and make sure that each number doesn't differ in value from it's neighboring numbers by more than 1, correct these errors by replacing these numbers with the value of the average of their neighbors, assign characters to this corrected array as it did before, and print both arrays.
The character assignments go as follows:
0=blank
1=.
2=,
3=_
4=!
5=+
6=*
7=#
8=$
9=&
I have the code written that opens the file and loads the array, but where to go from there. To me the obvious, although probably not best, way to do the assignments is to go through the array with a for loop and use a series of if statements to check for the value of the number at each index and assign the appropriate symbol.
Here is the code I have so far:
#include <iostream>
#include <fstream>
using namespace std;
int main() {
int size = 100, i, j;
prog >> size;
int **numArray = new int* [size];
[code].....
the value of C(k,n) are known as the binomial coeficient and can be arranged in triangle that was known as pascal triangle.
i was been asked to create a program that can display rows up to n=9 using print array function.
C(k,n) = C(k-1,n-1) + C(k,n-1)
how should i start?

How do I prevent user from entering characters or symbols instead of numbers?
int num;
cout<<"Enter a number."<<endl;
cin>>num;
Also, how do I prevent user from entering a number instead of a character?
char c;
cout<<"Enter a character."<<endl;

We've only covered up to Functions and how to use reference variables inside the function parameter.
One of the hw problem that was assigned was to write a void function that takes three parameters( num1, num2, num3) by reference and sorts their values into ascending order, so that num1 has the lowest, num2 the middle value, and num3 the highest value. For example, if user enters: 14, -4, 8, then the output should look like this:
-4
8
14
I've completed the program with a bunch of if/ else if statements but I was wondering if there was a more efficient way to sort the numbers. Bear in mind, we've only covered materials up to functions so I can't use any other new techniques that we haven't cover yet. Here is my code:
// This program will take three int parameters by reference and sorts their value into ascending order
//so that num1 has the lowest value, num2 has the middle value, and num3 has the highest value
#include <iostream>
using namespace std;
// declare function with reference parameter that with sort numbers
void sortNum(int &, int &, int &);
int main ()
{
[Code]....
I have to put these numbers in ascending and descending order . The interesting point of the function is that sortMe does NOT re-arrange elements in the array; instead, it uses a second array, an array of indexes for the elements in the original array and then sortMe sorts the second array based on the values in the original array. A sorted version of the original array can then be produced with these sorted indexes. I'm not sure why the function is working, even though I called it in main.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void sortMe(int array[], int sortedIndexes[], int size, char mode);
char option;
const int SIZE = 5;

What kind of code should i use for sorting numbers in both ascending and descending order? I don't know how to use bubble sorting either, is there another easy way to sort this out?

write a function named print_out that print all the whole numbers from 1 to n. test the function by placing it in a program that passes a number n to print_out , where this number is entered from the keyboard . the print_out function should have type void; it does not return a value. the function can be called with a simple statement:
print_out(n);

# include <iostream>
using namespace std;
void print_out (int x);
