C/C++ :: Calculating Letter Count From Array Of Pointers To Strings
Feb 28, 2015
I need to calculate how often each letter appears in a text file from a function that is called from main() with an array of pointers to char and how many pointers there are in the array. The code i have so far is:
I get no errors and it runs but it gives me the wrong output. I know my array is correct because when i print it in main() it is correct but each letter is incorrectly counted. When i give it the input .txt file of:
This is one line of a string
This is another
This is the third one
Wow heres another one
It counts a as 8
b as 1
c as 3
etc.
I have hand traced it and cant figure out why it isnt giving me correct values
I thought that if I were to access Buffer1 via BufPtrs[0], I would simply just put an * to it before printf()-ing or store it in a char[] (equivalent to a string).
I am new to c++. I am writing a program that reads in a text file and gives a count of how many times each letter appeared in the file. I got it to read the text file and do the letter count. B
X = 102 Y = 126 Z = 165 etc...
THAT IS WORNG
The sample output should be E = 165 T = 126 A = 102 O = 93 etc...
I got it to sort from lowest to highest for the frequency, but cant seem to get the appropriate letter assigned to it.
I try to use "rand" to create 100 string, I'm happy I succeed, but next step i wanna know how to count each number of letters and the frequency it shows.
Here is the code:
#include <stdlib.h> #include <string.h> #include <time.h> #include <iostream> // using namespace std; int main() { const char *c = "abcdefghijklmnopqrstuvwxyz";
how could i allocate memory is only needed for every string(as long as it is)? Cause in my code i allocate memory for 100 strings and for 10 characters for every string.
I have wrote the code below that compares to strings and sees if they are equals doesn't matter the order of the words . In the question we where asked not to use any library functions like the string functions in <string.h> and we have to do that all with pointers . I debugged my code and for some reason the first loop in the function keeps looping ...
#include<stdio.h> int IsEqual(char* str1,char* str2); #define SIZE 20 void main() { char str1[SIZE]="my name is monaya",str2[SIZE]="name monaya is my"; if (IsEqual(str1,str2))
This is my program and i dont know what is the better strategy to display the output perfectly align with the title, when i input a long variable or short the variable move and it does not align with its title. what can i do.
#include <iostream> #include <string> #include <string.h> #include <cstdlib> #include <cstring> #include <iomanip> using namespace std; struct book {
4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.
The assignment is to read a data file with a list of names, capitalize the first character of the first and last name by making an array and subtracting 32 from the character, and then outputting the names onto the screen. So far I have:
#include <iostream> #include <fstream> #include <string> using namespace std; int main () { string line; ifstream myfile ("Names.txt");
[Code] ....
this allows me to read a name, and capitalize the first letter of the first name. How to capitalize the first letter of the last name.
my code is working as expected except a slight error, i have to find min max and median values of an inputed array terminated by 0, the problem im having is with calculating the minimum, where when i enter 0 to terminate the program it uses 0 as the minimum value. my code is as follows
I have two doubts in the following code,the doubts are marked..PLs note that the following code is correct .This is a program to read 2d array using pointer ()i.e Dynamic array ,to calculate its rowsum and column sum and display this array along row sum and column sum.
#include<iostream.h> #include<conio.h> void main() { clrscr(); int *Val,*Rsum,*Csum; int MaxR,MaxC,i,j;
My program thus far is: (omitted code to shorten post and remove irrelevant information.
I don't know if it is because I have been working on other things and forgot how to proceed with the calculations and display, but I am just stuck. I'm not sure how to have the program read the numbers from columns 2 through 5 and then divide by 3. As you can see in my DisplayAverages() method I should have the ConsoleWrite and WriteLines done properly.
I am trying to fill an array with blank spaces and instead i get the number 32 over and over, i think this is the ANSI code for that character. how do i get the character itself?
So first I have to display a 2D array with all 0s, which is pretty easy.
#include <iostream> using namespace std; int main (){ int array[5][5]; for(int a=0; a<5; a++){ for(int b=0; b<5; b++){ array[a][b] = 0;
[Code] ....
So this displays
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Next, this is where it gets confusing. I have to create a virtual creature by storing a letter into a random position in the array (the array can be up to 20x20 in size). Then make a function that searches the array for creatures, so it would search for that character. When it finds a creature, it should randomly decide to either move the creature to an adjacent position, or have it stay where it is. After, it should ask the user to create a new creature, or quit.
So how would I go about adding & modifying the current code to achieve what is listed above?
iam trying to count the same numbers in an array just once like
38 38 40 38 40 37
the output should be 2 since 38 is repeated and 40 too but for my code the output is 3 thats an example of how it should be in a nutshell i want same number to be counted just once in the whole array
and here's my code :
#include <iostream> using namespace std; int main(){
So I already gave this a go and will post my code below. The question is about the last loop before the program cout's. i thought the count would keep track of the repeated numbers so i could display them but it does not. I italicized the loop i am referring to. or at least i tried to xD
#include <iostream> #include <iomanip> using namespace std; int main() { int inputs[30]; int numofloops; int maxvalue = inputs[0];
I must count the number of occurrence of all numbers in array , i wrote a code but it does not work properly
#include <iostream> int main (){ int i,n,tmp,counter=0; std::cout<<"Enter the size of the array:"<<std::endl; std::cin>>n; int *Array=new int [n]; int *counterArray=new int [n];
Arrays are by far the most fun to work with and I really need see if its possible to enable an array to count apples, pears, peaches, from a group of three each.
If any of the fruit groups were chosen how might an algorithm be put together to count how many were chosen from each group. But lets take into consideration that these fruit groups are not supposed to be randomly generated, instead they belong as an array with certain amount of chosen occurrences. To show how many fruits were chosen from each group example, 1 from group 1, 2 from group 2, 3 from group 3 the out put is the important part because it shows the group and the occurrence of that group. the algorithm should be able to display the group with an occurrence as well
I have to count the letters from a text file into an array so the first spot is the number of A's second spot number of B's and so on then take the array and sort it in decending order how could i do this without loosing track of where the numbers go so if there are more b's than a's they switch but how will i know where each letter has moved in the array after it has been sorted?
I'm trying extremely hard to understand pointers and I have the basic concept down.. I feel as though my knowledge of dynamically allocated pointers and pointers in general is not enough to understand the logic behind what I'm trying to do. The problem is that the donations array must be able to accept any number of donations. I've made it do just that, but there is also an array of pointers which must each point to the same element in the donations array. The program works if I assign int *arrPtr[100] for example, but it does not work if I try to dynamically allocate it to accept the same number of elements for donations entered by the user. Here it's the snippet
#include <iostream> using namespace std; //Function Prototypes
I am trying to initialize an array of pointers to an array of characters, I can do it in 3 lines but I really want to do it in one line at the same time keeping the #define.
