C++ :: Capitalize First Character Of Each Sentence In String
May 31, 2013
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>
what I'm doing wrong?

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've been agonizing over this all day. The assignment is to capitalize every other word in a user input string.
My logic is as follows:
1. I have the program get each character until it encounters white space (using for loop)
2. Then it should capitalize each character after the white space until it encounters another white space (using while loop).
My problem though is when i try to create a condition for while loop i have to terminate is when white space is encountered, but the very first character to start the while loop is a white space..
I was told to define boolean values, but after trying a few boolean conditions I'm still stuck..
Code:
#include <iostream>
#include <string>
#include <cctype>
using namespace std;
[Code] .....

I have an assigment to make program which deletes from sentence all words with character count which is equal to pair number , for example - [ I like C ] and the result of this program should be [I C] because the word like contains 4 characters which is pair and it should be removed.
So I started writing my program and I am stuck at this block of code -
#include <stdio.h>
#include <stdlib.h>
main () {
char text[100], blank[100];
int c=0,d=0,i,j;
gets(text);
[Code] ....
To explain what is happening - I go through all string and search for first ' ' space symbol and check its value. If it is pair then my program prints that it is not pair[because last character before space had not pair number of characters], but the hardest part comes in when i have two not pair words , because space takes one character and now when i check if i%2 == 1 the answer is false [0] for the second word .

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;
[Code] ....

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 have a problem with my code. You are given a sentence and you should censor the 4 letter words within the sentence.
#include<iostream>
#include<string>
using namespace std;
int main () {
int N;
cin>>N;
int k,j,counter=0;
[Code] ....

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:
while((str[i]!='.')||(str[i]!='!')||(str[i]!='?'))
it gives me an error for infinite loop.
Code:
#include<stdio.h>
int main() {
char str[100];int i=0,br=0;
printf("enter a string:");
gets(str);

I am trying to write a program that takes a sentence and reverses the word order.
For instance This is a Bird would become Bird a is This

#include <ctype.h>
int main (void) {
char input_buffer[1024];

So I'm trying to create a function that replaces any instance of a character in a string with another. So first I tried the replace() string member function:
In my implementation file
void NewString::ReplaceChar(const char& target,const char& entry)
{
this->replace(this->begin(),this->end(), target, entry);
};
Main program
#include "NewString.h"
using namespace ...;
int main()
[Code].....
Instead of replacing the the l's with y's it outputted a long string of y's. Also, NewString is derived from the string class (it's for the assignment). the header and whole implementation file, already tested.
I've also tried, instead, to use a for loop in ReplaceChar() but I need to overload the == operator and I don't know how I should exactly:
bool NewString::operator ==(const char& target)const {
if(*this == target)
return true;
[Code]....
I want the == operator to test if the value in the char array is equal to target but I'm not sure how to pass in the position. I'm guessing the this pointer in ReplaceChar() is not the same as the one dereferenced in ==() because target is never replaced by entry in the string.

So this is my homework: a user will enter a line of text, echo the input one word per line and capitalize each word(do not use toupper) and also needs word count and punctuation marks count. I know how to echo one word per line. How to capitalize each word without toupper? and how to do word count?

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.

I'm trying to get the int value of each character in a string and then add them all together so I can do a 1's complement of the total value. I'm trying to do simple checkum kinda of thing for verification of data.
For example: string DPacket = "Hello World!";
I would like to have each character added and do the ones complement. Will it be easier to convert first to int and then add or any other easier way? So my result should be the decimal value addition of each character and then do the ones complement to that.

I'm trying to write a program that capitalizes every other word of a user output. (ex: if input is "i love you", the output is "i LoVe YoU").
I am using a for loop (although an if loop might be easier?) and I'm assuming that it is possible to write this program using a for loop (although I may be wrong--maybe only if loops can write this program). I have everything down EXCEPT the last step where I have to print the entire sequence. What i have so far is:
Code:
#include <cs50.h>
#include <stdio.h>
#include <string.h>
{
// get user input
printf("Type a sentence: ");
string s = GetString();
[Code] .....
The code above basically only prints out the capital letter (ex: input is "hello", output is "EL"). I don't know how to print out the entire sequence.

I know how to remove certain characters from a string by using something like this:
Code: string str ("Hello world!");
erase (0, 6);
That's great if I want to do that manually, but say if someone entered a string, how would I automatically remove every other character they entered?

Copy some characters from char * arg to char * first using a loop with specific conditions.
Code:
char * arg;
// set arg some string...
char first_[25];
char * first;
int length;
length=strlen(arg);
for (n++; arg[n] != '}' || n>=length-1; n++)
strcpy(first,arg[n]); // first += arg[n]; I have strcpy(first,arg[n]); but arg[n] is char and strcpy expects char * ;
how to solve this?

It's been about two years since I last program c, now I need to do it for a basic project. How would I print out one letter in a string?
For example lets say I have a string called str=[Hello]. I want to display the third letter so just the "l". Here's what I have so far:
Code:
#include<stdio.h>
int main() {
char str[50] = "Hello";
printf("The third letter is : %s
",str[3]);
return 0;
}

I want to input a string, say: abcdaa so, the program should output:
a
b
c
d
In other words, the program will display each character for only ONCE!!!! And display their frequency. Here is my idea: user will input a string and such string will be copied into another string variable called "checker".There will be a loop and each character will be printed, BUT, first, the program will check if the character to be printed is not equals to all elements of the checker string.
I already have the function to count the frequency of each character
GOAL: to make a program that will accept a string and use the HUFFMAN CODING to compress it.
for(x=0; x<string_in.size(); x++) {
cout<<" "<<string_in[x]<<endl;
for(y=0; y<string_in.size(); y++) {
if(checker[y]==string_in[x])
break;
else
checker[x]=string_in[x];
}
}
