C/C++ :: Find Length Of First Sentence In Input String
Feb 13, 2015
I have a question about finding the length of first sentence in an input string.
For example, let the input string be: dream in code. community learning
The length of first sentence is 13 (blanks are included). My question is how to create conditions for multiple punctuation signs (!,?)? If while loop goes like:
printf(" Enter a line of Morse Code for decrypting"); scanf("%s",phr); len=strlen(phr); for(a=0;a<36;a++) { if(strcmp(phr, morse[a])==0) printf("%c", alpha[a]); };printf(" ");
The output :
[output] Enter line to encrypt: ..... -.... --...
converting... 5 [/output]
It should read all code, including null. between coded letter one space, between coded word three spaces.
Write a program that calculates statistics on word length for a sentence. The sentence isterminated by a ',' For each found length of a word the number of words of that length is printed. Only those lengths that are found in the input are printed. Only letters from a-z or A-Z are allowed to form words. Words are separated by a space. No punctuation characters other than ',' are allowed. If any other input character is recognized or the input is longer than 80 characters the program displays "NOT VALID" (see Hints).
Note, that in the case that no word is present in the input, nothing is printed.

Enter a sentence: Bolt was expected to use the super bark.
So, the problem is that if i inpute a text like"abc abcd abc abc" the result will be like
"length 3: 3 length 4: 1 length 3: 2".
So when the program already compared 1st (here 3) element with others, this element will not be comparing again, but i have the 3d element with same length, and it that case, the program compare it with remained elements and print 2. How can i rework my code, if i don't wont to compare already compared elements.
Second problem is that i need to get results from lowest length till highest.
I need to be able to find every possible permutation using all possible values of a char. But I have to make it be able to form permutations from a length of 1 to variable N. For example, if N=3, I need it to be able to come up with
How could I do this. (I would like to avoid recursion, since N might be as large as 50 or 60 and using recursion would most likely cause a stack overflow)
I am working on a c-programm. In this program I have to convert the amount of money I read on two variables into the corret format. I got Euros and cents on 2 ints. But now I want to add both of those variables in a String (char array). Also i want to find out the length of the new char array.
Ok my assignment has me doing vector math with some canned code provided for me by the instructor This is the header file to the class I'm working with and the .cpp file as far as I've gotten it.
#pragma once #include "Scalar.h" class Vector2D { public:
Vector2D(); Vector2D( const Vector2D& ) ;// copy constructor Vector2D( Scalar element[2] ) ; // initialize with an array
[Code] ....
I'm having trouble seeing which data members I'm multiplying together and what the initial state, continuing state, and after loop action I'm supposed to be using in the for loop.
I'm trying to find vertical paths of length n through a 2D grid of numbers. Paths may connect orthogonally or diagonally. An example grid and an example possible path looks like this:
A example possible path of length n = 3 is running from (3,2) to (3,4) - All 1s ...An example of n = 4 is the run of 3s (1,1) (0,2) (0,3), (0,4)
What is an efficient algorithm for solving this kind of problem? I would like to solve (ideally) millions of grids, giving a list for each grid of all possible paths of length for n = 3-6.
I am trying to write a program that ask the user to enter a sentence and then a word to be searched for in the sentence. The program must then search for the word in the sentence in a loop and continue to output each place the word is found. For example if the sentence is : I like pickles, pickles, pickles
and you searched for pickles it would return pickles found at 7, pickles found at 16, pickles found at 25.
I am having trouble writing the equation to make the find keep searching after each occurrence of the word being searched. Here is the code I have so far
HTML Code: #include <iostream> #include <string> using namespace std; int main() { string paragraph;
Write a function that accepts a pointer to a C-String as an argument and capitalizes the first character of each sentence in the string. For instance, if the string argument is "hello. my name is Joe. what is your name?" the function should manipulate the string so it contains "Hello. My name is Joe. What is your name?" Demonstrate the function in a program that asks the user to input a string and then passes it to the function. The modified string should be displayed on screen. Optional Exercise: Write an overloaded version of this function that accepts a string class object as its argument.
#include<iostream> #include<cctype> #include<cstdlib> using namespace std; void capitalize(char sentence[], int const SIZE);
[Code]...
Not even sure if I'm headed in the correct direction, but I'm getting the following errors:
E:CPT-233Sentence Capitalizer.cpp In function `void capitalize(char*, int)': 34 E:CPT-233Sentence Capitalizer.cpp call of overloaded `strstr(char&, const char[2])' is ambiguous note E:CPT-233<internal>:0 candidates are: char* std::strstr(const char*, const char*) <near match> note E:CPT-233<internal>:0 char* std::strstr(char*, const char*) <near match>
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.
I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code: #include <stdio.h> #include <string.h> int main() { char str[100]; int i = 0;
[Code] ....
Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0; at the beginning of the code and then made Code: count = strlen(str); why wouldn't i have the same result? Is there a way to do it also?
In this code, i declared a string constant and trying to print the length of string. I know that if i write char a1[7] or char a1[] than it runs and give aggregate output, but in this case it is giving double length of string.
For the following program, I'd like to make sure the user input is between 1 and 40 characters. To do this, how would I complete the if statement below?
Code: char p_input[41]; printf("Enter a name (1-40 characters):"); fgets(p_input, 41, stdin);
I am trying to make a program that will read in input in the following format:
| ...text... || ...more text... || ...still more text...|
i.e. every bit of "text" that gets read in is bracketed on either side by the "|" character.
The buffer that i read them into can be of a maximum length of 101 (100 characters plus a terminating null character); this is how I am currently reading in the input:
How might I design this program so that, should any of the text appearing between the "|" characters exceed 100 in length, it exits and returns a warning?
I want to ask for a number as an input during runtime and then create an 2-dimensional array of size as specified by user. i.e. if the user inputs 3, the array should be of size 3X3, and likewise...
I'm trying some codes about string arrays and taking array length. But i have some problems. I can't get length of string and can't send to a function.
------------------------ #include<iostream> #include<cstring> #include<string> using namespace std; void GetLength(string); std::string Words[]={"table","gun","programming"}; int main() {std::string InputWord;
How would I make it so that I can have someone input the length, width and height for all 3 boxes and then have it output the sum and average volume? Here's an example of what I would like:
INPUT - Enter Box 1 (Length, Width, Height): 10.1 11.2 3.3 INPUT – Enter Box 2 (Length, Width, Height): 5.5 6.6 7.7 INPUT – Enter Box 3 (Length, Width, Height): 4.0 5.0 8.0 OUTPUT – The sum of the volume is 812.806 OUTPUT – The average volume is 270.935
Here's my original code:
#include <iostream> using namespace std; double box(double length, double width, double height); // use double data int main() { double sum; sum = box(10.1, 11.2, 3.3) + box(5.5, 6.6, 7.7) + box(4.0, 5.0, 8.0);
I can't find any method of retrieving the length of an array except for doing this:
string first[] = {"a","be","see"}; int length = sizeof(first)/sizeof(first[0])
This is a very unconventional way of getting the length of an array.
first->length() would return 1 because it returns the number of letters in the first element of the array (which actually makes no logical sense).
first.size() would return 1 aswell as it's practically the same thing.
Since getting the length of an array is such a fundamental feat, how come I can't find a decent method of doing it? Is there no buildt in method for this? If there is not, why has it not been implemented in the std?
The input consists of one or more packets followed by a line containing only # that signals the end of the input. Each packet is on a line by itself, does not begin or end with a space, and contains from 1 to 255 characters.
