C++ :: How To Turn A String Word Into Letters
Dec 9, 2013
I'm having trouble trying to turn a word into letters. I've seen other posts but they deal with a sentence and it only outputs the words only. What I want to know is how do they take a word (Ex: "word") and break it into individual letters, where I want to store them in a vector of string?
If it's not too much trouble, I would prefer without using pointers or "std:: " marks, since I am trying to avoid pointers and I'm using "using namespace std" all the time.
Ex:
In the example "word", it should output into:
"w"
"o"
"r"
"d"
and I will push them back into a vector of string where each vector element contains a letter.

I am building a linked list and i need to display function i have. The display function displays all the letters of the word entered instead of the word itself. below is my struct, one of my functions and the display function.
Code:
//-----------struct ------------//
struct Node
{
char data;
struct Node *next;
}*Head;

i'm trying to replace letters in a word...here's the code so far
#include <algorithm>
#include <iostream>
#include <string>
using namespace std;
int main (){
string s;
[Code] ...
The problem is if i type "nm" i'm not getting "mn" as the output, it's "mm"
I'm not trying to swap letters between them

How would one cycle through a turn order in a turn-based game? I was thinking an array of every creature (including the player) and have a pointer to the array++ after the turn, but I couldn't put all the objects into an array.

int main () {
string integer1;
string integer2;
cout <<" enter your first number: " << endl;
cin >> integer1;
cout << endl;
cout << integer1 << " is your first number" << endl;
}
Now how do I turn the string integer into an array?

I am currently working on an assignment.
#include <iostream>
using namespace std;
int main(int argc, char *argv[]) {
char letter;
int count = 0;
double ppl = 0;
double finalCost = ppl * (count - 1);
[Code] ....
I am trying to create a word counter program that asks for the price per letter and then asks for the sentence they are writing. The app should then calculate the number of letters and give the total cost similar to:
You have 40 letters at $3.45 per letter, and your total is $138.00.
Everything compiles fine but when I run it the inputs don't work and it outputs:
You have -1 per letter, and your total cost is $-0.

I know strings are essentially just arrays of characters, so what would be the easiest way to take each individual digit and put it into a separate space in an array?
ex.) *str = "90210"
array[0] = 9
array[1] = 0
array[2] = 2
array[3] = 1
array[4] = 0
All my attempts at achieving this just result in an array full of garbage numbers. What I've done is
Code:
int *array;
array = malloc(sizeof(int)*(strlen(str));
for(i=0; i<strlen(str); i++) {
array[i] = str[i]
}
also, I should mention that the string will be defined in main, and its converted into an array in a separate function.

I'm doing error checks in C and I'd like to know how to restrict the input of a string to 2 letters and if it is exceeded, i'd like to loop and ask for the code to be re-entered.
Code:
for (i = 0; i < code7; i++)
{
printf("Enter number of items: ");
scanf("%d", &item_qty[i]);

I am creating a program where I count all the letters of the alphabet from a user submitted string.
How would I go about this?
I am completely new, so simplicity is best. I am suppose to use arrays.

My problem says: Have the user enter a number from 1-80 then print out a string of random letters(a to z lowercase) of that length.
I have been able to enter the number and output the correct amount of letters but i can't figure out how to get them to be in a random order and not in alphabetical. Here is what I have so far.
#include <iostream>
using namespace std;
int main() {
int i=0;
int num;
cout<<"How many letters do yu want in your random string?";

I've to use recursion function that return if the string has a same letters:
for example: - fff = true
- fFf = false
I did this but the return answer is always: NOT!
bool iSameLetters(char str[SIZE]) {
if(str[0]=' ')
return true;
else {
if((str[0] && iSameLetters(str+1) == str[0]))
return iSameLetters(str+1);
return false;
}
}

I am new to coding Here is the problem. Have a program prompt the user for a filename to open. Change every alphabetic character in the file to a capital letter. Numbers and special characters should not be changed. Print the output to the screen.
Here is my code so far but i am only returning the last line of text capitalized from the file. I am trying to get the program to display all of the three lines of text from the file capitalized. The program displays the file correctly before i try and convert everything toupper();
Code:
Code: #include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <ctype.h>
int main()
{
char line[81], filename[21];
int i;
FILE *inFile;
[Code]...

write a C program which repeatedly reads in sentences from the user and reports on how many capital letters are in the sentence and how many punctuation characters. Your program will stop asking for input once the user has entered in a blank line. Consider the following example usage with the program. User input is marked in underline:
Enter a sentence: John and Mary went to Fred's house.
You used 3 capital letters and 2 punctuation characters.
Enter a sentence: I like A&W more than McDonald's.
You used 5 capital letters and 3 punctuation characters.
Enter a sentence:
Good bye!
Hint: make use of the standard C functions ispunct and isupper. Other requirements. You must make two functions.
Make a function called find_characters, which has a return type of void, and which has three parameters: one of type char * (a string to find characters in), one of type int * (a reference to int variable indicating how many capital letters are in the string) and the last one also of type int * (a reference to an int variable indicating how many punctuation characters are in the string). Your find_characters function should scan the string and update the two variables it has references to.Make a main function.
This function should repeatedly read in a string from the user, call your find_characters function, and output the information returned to it by the find_characters function indicating how many capital letters and how many punctuation characters were in the string. Your main function should stop reading in input when the user enters in a blank string (i.e., the user just hits enter without entering anything else in). You may assume that the user will not enter in a sentence longer than 100 characters

I need to write a C function that generates a random character array (i.e. string) of uppercase letters - getchar and putchar are the only IO functions that I can use. Below is what I have already - I am iterating for as many times as I am required to, and am modulating rand() by 25, (total letters in the alphabet). I'm trying to see how to get the random letter from the % 25, and also how to do this without toupper() [not sure if I can use that function].
void getRandomStr()){
char str[40];
for (int i = 0; i < 40; i++){
char c = rand() % 25);
str[i] = toupper(c);
}}

This for loop replaces the stars ******** in an array that contains a word to be guessed with the correct letter (c) that the user inputs if the word contains that letter.
Problem: After every guess the same hidden string of stars ******* is displayed instead of ex: ***W**** (assuming W was entered by the user)
How can I update the old ******** string in the Stars array with the new string that includes the correct letters chosen, so after every correct guess at a letter in the word a new string is displayed including the correct letters chosen?
I'm pretty sure I have to use strcpy but not sure how to implement it using a loop.
Code:
for(i = 0; i < strlen(unscrambledWord); i++) {
if(unscrambledWord [i] == c) {
Stars[i] = c;
} }

1. Create a variable named index and nitialize it to zero(0)
2. Prompt for and input a string value from thekeyboard. Store the string inthe string variable newstring[80].
3. While (newstring[index] does not equal ‘ ’).
i. Display the character at newstring[index] followed by a NL
ii. Increment index ====================================== ...
And this is what i have done so far and i dont know where I am wrong ...
Code:
#include<stdio.h>
int main()
{
int index = 0; //initialize index to zero since first elementin an array is numbered zero
char newstring[80];

I want to see if the value of a string equals a certain text. But I can't make it. There are two problems :
1) It seems 'tolower' doesn't work with strings. What to use then?
2) When I delete tolower, it works, but I have an output of "You didn't enter 'add'" even when I do enter 'add'. What's the problem? Is it due to the null byte? What to change?
#include "stdafx.h"
#include <stdio.h>
#include <math.h>
#include <string.h>
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[]) //This was added automatically by Visual Studio.

I'm trying to read a string and then compare it to a word.
My code:
char* cmd = "start";
std::cin >> cmd;
if (strcmp (cmd, "eval"))
eval ();
When the program gets to the cin part, it breaks.

I have a difficulty with string methods for some reason. I tried solving a question from my book, which requires me to capitalize the first letter of every word in a string. I kept trying for maybe two hours yesterday, re-reading the string chapter to see if I'm forgetting a certain method or if something similar was discussed in the examples but I didn't find anything. I also googled it, and found a few answers, none of which I understood. They mostly had keywords or methods I wasn't familiar with. Anyway, here's where I am so far.
class Program {
static string UpperCase(string s) {
int place; string b, st1, st2,st3; char letter;
for (int i = 0; i <= s.Length - 1; i++) {
if (i == 0) {
[Code]....
The code compiles without any errors, but when I enter a string it capitalizes correctly for the first two words and then it starts capitalizing letters in the middle of the words.

I have been trying to get this to work for a while now - with no success.
Basically I am trying to write a function which the returns the first word of each input sentence in a single string - this is part of a larger cryptography program I am working on.
So for example, if this string was passed into the function:
"This is what I mean. Is it right? A poor puppy abandoned. Secret torturing of dogs are happening. Message: be on the watch."
It should return:
//declared in class "steganalyse"
string cyphertext;
string punctuation = ".?!;:'";
book is_first_word
[Code] .....
But this only returns the first word:
This
Any other way to return the first word of each sentence in a string.
