C :: Make A String Out Of Part Of A String
Dec 9, 2013I have a string that contains a various number of lines which are each separated by and so what I want to do is to put each line into a node in a linked list.The relevant sections in my code are as follows:
Code:
typedef struct line *Line;
struct line {
char *text;
int lineNum;
Line next;
}
[code]....
Code:
strncpy(curr->text, text[prevPos], subLength);
With this line, I was hoping to make curr->text a string that is length subLength and begins at position prevPos in the text string. Except text[prevPos] is treated as a single character and not a string that begins at that position.

C++ :: How Sub String And Math Can Be Used To Make Logical Decisions
Dec 1, 2014This is an example of how sub string and math can be used to make logical decisions without using if/elses or switches. It works because of this equation

C++ :: make Program That Can Type String Into Another Window?
Apr 26, 2013I am trying to make a program that can type a string into another window. I have gotten it to the point that it can type the string, just not correctly. It will type random numbers and not the given string. The key event uses ASCII code for the arguments, and I don't see anything wrong with my numbers. Here is the code I have so far.

C :: How To Make A Function Read From Array A But Put Select Parts In Array B
Jul 30, 2013im trying to read in 1 array and get 2 as outputs from 3 different functions.my read array is easy enough were im getting confused is how to read that array, separate it and take out only the parts i want and place them into a 2nd, then again a 3rd array.i have the following so far:
Code:
#include<stdlib.h>#include<stdio.h>
#include<unistd.h>
#define SIZE 10
}
[code]....
this compiles without a complaint, but when i go to run it no longer responds after taking the 10th element (well 9th if counting from 0).I think i have the if correct for the even odd section, but when i try to populate B or C array with the output of that if statement from A is were i think things are dying...
C++ :: Determine Number Of Times Change Each Specific Character In String To Make It Palindrome
Feb 19, 2015I'm trying to determine the number of times I have to change each specific character in a string to make it a palindrome. You can only change a character one at a time from the end.
Example: "abc" -> "abb" -> "aba" should print 2. "aba" will print 0 because it's already a palindrome. "abcd" -> "abcc" -> "abcb" -> "abca" -> "abba" will print 4 because it took 4 changes to make a palindrome.
I'm not too sure how to approach this - I figured out the case where if it's a palindrome (if reversed string is the same) then it'll print out a 0.
int main() {
int number;
cin >> number; //expecting a number for first line user input
for (int i = 0; i < number; i++) {
string str;

C++ :: How To Make Array With A Range Of Numbers From 1 - 9 Only
Jan 29, 2013I want to make an array with a range of number from 1-9 only. So if the user entered more than or less than the number indicated it will be error and ask the user to reinput the data. So far my code can be used to do so that if the user enter the number one by one... But if the user entered all the number in one shot the reentered value will be prompt to the back automatically for some reason...Let say 10,2,3,4 which was suppose to be 1,2,3,4 became 2,3,4,1 instead... here is the code:
#include<stdio.h>
void main() {
int num[4][4];

C++ :: Make A Function That Checks If Array Is A Permutation
Feb 16, 2014I need to create a function with the following prototype:
bool isPermutation( const unsigned a[], unsigned elements );
unsigned a[] = {3, 0, 2, 1};
bool P1 = isPermutation( a, 4 );
would set P1 to true because the set of subscripts is {0, 1, 2, 3}, and the values are just a reordering of those values. On the other hand,
unsigned a[] = {3, 0, 2, 3};
bool P2 = isPermutation( a, 4 );
would set P2 to false because the set of subscripts is {0, 1, 2, 3}, but there’s no value that’s equal to 1.
I'm not exactly sure how to do this. I thought about it a couple different ways. I first thought about taking the range (max/min) and then checking to see if the numbers in between are equal from each other, distance-wise.
I then thought that I should just make this basically a sort function (I used bubble-sort), and then to just check if the numbers are equi-distant from each other.
This is my basic bubble-sort. Perhaps it is wrong, but I'm not certain...Perhaps I am making this function harder than it has to be.
unsigned temp = 0;
for (unsigned i = 0; i < elements; i++){
for (unsigned k = 0; k < elements-1; k++){
if (a[k] > a[k+1]){
temp = a[k+1];
a[k+1] = a[k];
a[k] = temp;
}}}
Should I do a sort like this, and then do something where I subtract a[i+1] - a[i], and see if that equals '1'?. I would think that would mean they would have to be equidistant. Even if this is correct, I feel like it could be more efficient.

Visual C++ :: How To Make Random Array To Not Repeat
Feb 17, 2013Here is my code for a simple game. paste it and try it.
#include <iostream>
#include <string>
#include <ctime>
#include <cstdlib>
using namespace std;
int main (void) {
stringg[4],
[code]...
What they do (enter 4 actions)?
";
for (int ai = 0; ai < 4; ai++)
getline(cin, a[ai]);
cout << "
Where is happening (enter 4 locations)?
";
for (int li = 0; li < 4; li++)
getline(cin, l[li]);
for (int c = 0; c < 4; c++)
cout << g[rand() % 4] << " and " << b[rand() % 4] << " are " << a[rand() % 4] << " from a " << l[rand() % 4] << endl;
return (0);
}
At the end in the 4 lines some of the names, actions and locations repeat. How do I make them to not repeat and use every name that you will enter? do I need random_shuffle? How can I integrate it in my code?

Oct 17, 2013So for class I have to make an array of structures for a basic contact list in a phone.
I understand the bones of the program and how to go about doing most of it but as far as arrays of structures go I am blind.
Code:
struct phone

char FirstName[16];
char LastName[16];
int Number[11];

struct phone numbers[friends]; //friends is a variable assigned by the user What I am a bit confused about is say the user enters 30 as how many friends they have. How would I assign a value to the 3rd struct for LastName?

C/C++ :: Enter String Into String Array Via Cin Or Getline
Mar 29, 2014Ok so I searched this site, and google string arrays, but I couldn't find anything on how to create an array to accept string input. In other words the strings are unknown, until the user inputs them..
so code would say input a name..user enters Tom, and its inserted into the array.. and if another name is entered ..lets say Lisa..Lisa is added to the array..so now in the array we have tom and Lisa..
Everything I read only shows the array already having the strings declared...
string n;
string name[n]={};
