as i am doing an encryption program on a playfair cipher. I am now stuck on a problem on decryption.If my string is helloworld (without a space), it will decrypt normally.However , if my string has a space in between it. Let`s say Hello World, it will not decrypt normally.How do i take into account the space that is in between hello & world?
I'm trying to find a < character in a document, get it's position. Then find > and get it's position. Then i want to delete all things between that but runtime is terminating my process so i don't know what to do.
So i have this program that's supposed to count all the characters including the spaces without using strlen but it only counts the number of the first word's characters and it does not include the rest of the words after the first space. how do i include spaces in the count?
I want to make a program that receives the number of lines and collumns of a matrix, a matrix of char, the number of pairs of coordinates and the coordinates. the program has to return the char (or chars) that are on those coordinates on the matrix.
Example:
receives 2 3 ABC DEF 2 1 1 1 2
returns
AB
this is how i tried to solve this problem:
Code: #include #define MAX 1000 int main() { int nlin, ncol; char mat[MAX][MAX]; int x[MAX], y[MAX]; int ncoords; int l, c, n;
/* receiving variables and storing matrix.*/
[Code] .....
For some reason that i can't seem to find, this solution is not right.
Write a function to read and display the contents of names and marks. You then ask the user for a name and using the linear search return the index to the user. If -1 is returned then the name is not in the file. Otherwise write out the name and mark for that student.
Next, sort the arrays, write them out and then ask the user for a name to search for. This time use the binarySearch to return -1 or an index. Display the student's name and mark if found.
void getNames(ifstream& inStream, string names[], int marks[], int numElts); int linearSearch(const string names[], int numElts,string who); int binarySearch(const string names[], int numElts,string who); void selectionSort(string names[], int marks[],int numElts); void displayData(const string names[], const int marks[], int numElts); [Code] ....
Now I have worked up some stuff in parts but I am so lost and confused with these specific requirements: Previous questions asked me to sort out a linear search, a binary search and
LINEAR SEARCH:
int searchList(int list[], int numElems, int value) { int index = 0; // Used as a subscript to search array int position = -1; // To record position of search value bool found = false; // Flag to indicate if value was found
The program then asks the user for a search string, which may contain white space. The program should search the file for every occurrence of the search string. When the string is found, the line that contains it should be displayed in the following format
nnnnn:Line Contents
That is the line number of the line, 5 columns wide, right justified, followed by a colon, followed by the contents of the line.
And this is what I've got so far:
Code: #include<iostream> #include<fstream> #include<string> #include<iomanip> using namespace std; int main(int argc, char *argv[]) { ifstream inFile; string fileName,
[code]....
But this doesn't work. It prints everything in the file, not just the lines where the string is found.
I want to separate this binary string every 4 characters..I am trying to get a better understanding of how variables are stored in memory and I am looking at their binary address for a pattern..I see a pattern for the last 4 bits
#include <iostream> #include <bitset> int main() { using namespace std; int x[100];
I am having some trouble tokenizing some strings in C. I am trying to take in a string dynamically and spit print it to the console tokenized using the spaces as delimiters. I have tried using frets() and scant() as well as playing around with pointer values to no avail.
Now, I have an assignment in which I am to accept arguments from the command line and copy them into a cstring and display said cstring unmolested. Then I should store it into another cstring but ignore all punctuation, spaces and capital letters. Like this:
./a5 Marge lets Norah see Sharon's telegram As is: Marge lets Norah see Sharon's telegram ---->: margeletsnorahseesharonstelegram <----: margeletsnorahseesharonstelegram Sequence entered is a palindrome =======================================================
Finally I am to chaeck to see if it is a palindrome. Most of it works and if no spaces are entered nor punctuation it works. However, punctuation causes it to malfunction.
char *FormSeqProc (int argc, char *argv[], char seqAsIs[]) { int len = 0, n = 0; for (int p = 1; p < argc; ++p) { len += strlen(argv[p]);
My application is processing a large amount of data (approx. 50 - 100 GB of txt data). given the machine regular user usually has, my app is writing some tmp data into a local tmp directory. and this is working just fine until users get comfortable with my software and start changing that content of local tmp dir (while the program is running). which does not give any problems like crashing a program if handled at the right time but produces wrong results in the end. now this is not my problem but i would still like to somehow restrict users from even peeking into the tmp dir. I am just tired of getting emails saying my software is cr.... (maybe it is but i don't think it is because of that)
So is it possible to somehow encrypt the entire dir so that only the program has access to it . it would be even better if the dir could look as some encrypted index file so that when user sees the warning :
I just want my program to run continuously until someone enters 0 to exit it. I tried doing while(x=1) and looping my entire block of code. Also there is a switch one is a for one is a while loop both doing the same function. I have basic error checking and whatnot.
/*This is a program that gets a user to input a starting and ending value. The code then prints the number ie 1 and 5 would be (1,2,3,4,5) and all the squares and cubes. There is a case statement asking weather you want to run it as a for or as a while loop. The choices are case sensitive. */
#include <stdio.h> #include <stdlib.h> #include <math.h>//allows for power and cube function int x; int main(){
I would like to store the entire content of a file in a single c-string variable or in a standard string class variable. Is there a function that will do this for me? I am familiar with functions that get one character or one line at a time but I don't think I've encountered a function that gets the entire file. Does this function keep or disregard the end-of-line character? If no such function exists, I would write my own function to create and return such a variable.
I am working on a drink machine simulation. I have a text file that holds the prices, names and inventory. My problem is It won't let me set my prices at 1.00 or higher. Ex: I set the price to 1.50 in the text file then when it reads the info and stores the price it only stores .50 instead of 1.50.
