Nov 7, 2014Code:
#include <stdio.h>#include <string.h>
int main() {
char pin [] = {1,2,3,4};

C++ :: Generate 100 Random Integers Between 0 And 9 And Displays Count For Each Number
May 3, 2013I've been currently stuck on a C++ problem. Here's the question:
Write a program that generates one hundred random integers between 0 and 9 and displays the count for each number. (Hint: Use rand()
% 10 to generate a random integer between 0 and 9. Use an array of ten integers, say counts, to store the counts for the number of O's, l 's, . .. , 9's.)
I think I'm pretty close, but I keep on getting "0" for the occurrences (or counts) of each random integer.

C :: Fixing Size Of Array As Opposed To Using A Pointer
Oct 15, 2014If I have an array and all I have is an upper limit on how big the array can get, and if the number of elements that get added can be considerably smaller than this limit, is it always the right choice to declare a pointer and just reallocate extra memory whenever the array grows? For instance, instead of declaring int a[max] I can declare a pointer int *a and than just realloc when I add elements.

C :: Program That Accepts First / Last Name And Displays It Through Another Function
Sep 25, 2014I was trying to code a program that accepts your first name and then last name and then displays it through another function. I have checked that the assignments are between similar type of variables and pointers, but I don't seem to get it right.
When first input is taken and then second one, the first one's value changes to same as the second. E.G if first name is L and second name is S and after second input both variables, first and sec, become equal to S. Why?

C/C++ :: Assigning Symbols To Numbers In 2D Array?
Sep 11, 2014I'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];

C :: Program That Displays Menu Of Commands For User To Choose From
Aug 1, 2013I've read that we can write a program that displays a menu of commands for the user to choose from.We can write some functions that implement these commands, then store pointers to the functions in the array :
Code:
void ( *file_cmd[])(void) = { new_cmd , open_cmd }; // 2 cmd's for simplicity
We can get a similar effect with a switch statement but using an array of function pointers gives us more flexibility since the elements of the array can be changed as the programm is running.
I decided to write an example about this in order to understand better the context, I am facing some problems though :
Code:
#include<stdio.h>
#include<stdlib.h>
typedef void (*p_foo) (int);
void foo(int x);
void foo2(int y);

C/C++ :: Find Repeated Words In String And Symbols Between Them
Oct 29, 2013I need to find 2 similar words in one sentence and i need to find how much symbols are between these two words. I can't figure out the algorithm.
For example sentence would be-
This is nice table and nice chair.
Similar words are- nice
Symbols between them are 11 or 8(dont know if space is count as symbol)
int main()
char text[200],*dist;
printf("Enter one sentence
");
gets(text);
Maybe first of all would be
dist=strtok(text, " ,.!?");
while(dist!=0)
{
printf("%s
", dist);
dist=strtok(NULL, " ,.!?");
}
and it wil output each word and maybe then can search for similar words if there would be 2 strings then i would use strstr but i dont know how to do with one string.
