I have a problem who must print the sentences who have lenght more than 20 characters. I dont know why, but it prints just the first words. Look what i made.
#include<stdio.h>
#include<conio.h>
int main()
[Code]....
For instance :
Give the number of sentences : 3
First sentence : I like the website bytes.com
Second sentence : I like more the website bytes.com
Third sentence : bytes.com
After I compile the program it should print the first two sentences.
How I can manipulate certain strings. This program here is supposed to randomly scramble any word/sentence input. However, I notice that even the empty spaces get moved; is there any way to stop that from happening? I would want the empty spaces to stay in their input positions.

I need to write a program that reads a paragraph from a file (i dont know its length) and i need to read it with spaces
i thought of using getline() function but there were problems:
1) how to detect End Of File
2) how to use getline while reading from file
and thought of reading one character at a time but it didnt read spaces
How do I store pointers to a struct in an array ? I am using sprintf to concatenate some values together and then output it to an array in its 1st argument. A portion of my code is shown below.

Background: I'm writing a convolutional encoder (and decoder, eventually) for a microprocessor (PIC24), for which I'm using structs and pointers to move from state to state. So far as I'm aware, everything I'm using in the PIC involves nothing other than ANSI C.
I have a little experience with structures, having written a linked-list program for a class a couple years back, but nothing since and never used structure arrays. I have the feeling I'm missing something basic here, which is what's so frustrating. The most confusing error (and I suspect the root of most of them) is the 'state undeclared', which I just can't figure.
The errors I'm getting are:
encoder.c:11: warning: 'struct memstate' declared inside parameter list
encoder.c:11: warning: its scope is only this definition or declaration, which is probably not what you want
encoder.c: In function 'state_init':
encoder.c:22: error: two or more data types in declaration specifiers
encoder.c:25: error: 'state' undeclared (first use in this function)
encoder.c:25: error: (Each undeclared identifier is reported only once
[Code]....
Code:
Code: //Includes
#include <stdlib.h>
//------------------------------------------------------------------------------
//Creates state machine and passes back pointer to 00 state
void state_init(struct memstate* startpoint)
{
extern struct memstate
{
char output0; //output if next input is 0

NB: I'm aware that at the moment, this code will do nothing except spin round that do-while loop. Once it's actually compiling I'll drop in some simple button-based test code so it'll check for the correct output.
Write a program that uses a record structure to store a Student Name, Student ID, Test Scores, Average Test Score, and Grade. The program should keep a list of test scores for a group of 6 students. The program should ask for the name, ID, and four test scores for each student. Then the average test score should be calculated and stored. The course grade should be based on the following scale:
Average Test Score Course Grade
------------------ ------------
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D
59 or below F
A table should be displayed on the screen listing each student's name, ID, average test score, and course grade. Implement with functions.
My code runs but it isnt returning anything (readable/correct) and i have no clue why. This is what i have so far:
#include <iostream>
using namespace std;
const int columns = 4;
struct StuRec //user defined datatype {
int id[6];
char names[6][20];

it compiles completely but at the end instead of showing the student name ID average score and class grade it shows.... [URL] .....

In Unix (HP-UX) and Linux, the output of above program will be:
t.a=Helloworld!
Instead of the value of t.a ,i.e, "Hello" only.
Why such output? And what is the trick here to print the only value of t.a.
I'm wondering how to access Buffer 1 and 2 via the pointer array;
Code:
char *BufPtrs[3];
char Buffer1[64];
char Buffer2[64];
BufPtrs[0] = Buffer1;
BufPtrs[1] = Buffer2;
BufPtrs[2] = NULL;
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 trying to make a pointer to pointers for strings with malloc but my code isn't right.I tried something like that.
Code:
char **p;
**p=malloc(100*sizeof(char*));
for(int j=0;j<100;j++)
*(p+j)=malloc(10*sizeof(char));
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";

I am trying to copy string Line BY Line from text file into array of pointers. lets say file has only two lines for example.
This is an apple.
This is another apple.
I want to copy both of these lines from file to array of pointers. Below is the code which i am trying to use for this.

#include <iostream>

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:
#include<stdio.h>
#include<string.h>
#include<ctype.h>
#include<stdlib.h>
[Code]....
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'm trying to create an array of pointers to pointers which will point to array of pointers (to strings) I tried

I am a little confused while comparing char pointers to integer pointers. Here is the problem:
Consider the following statement;
char *ptr = "Hello";
char cArr[] = "Hello";
When I do cout << ptr; it prints Hello, same is the case with the statement
cout << cArr;
As ptr and cArr are pointers, they should print addresses rather than contents, but if I have an interger array i.e.
int iArr[] = {1, 2, 3};
If I cout << iArr; it displays the expected result(i.e. prints address) but pointers to character array while outputting doesn't show the address but shows the contents, Why??
How can I extract the number out of the string:
string my_sting = "item code = 9";
I want to get the '9' out of the string and store it in a separate int variable. I tried using sstream library and was having trouble.
I am practicing with C++ since I done most of C already and I have a problem with reading spaces from a .txt file.
I created a little program that creates a wannabe Cube in wannabe 3D xd, well to appear as 3D like:
Code:
cout << " O------O" << endl;
cout << " / /|" << endl;
cout << " / / |" << endl;
cout << " / / |" << endl;
[Code] .....
The actual code is a bit longer since it offers you to input the size and then it draws the pic. Now that wasn't so hard and I've done that but now I wanted to implement the "MessageBox" func for output.
I managed to write the cube in file cube.txt but when I'm reading from it 1 char at a time since I need to output as char array it avoids all spaces and new lines and just puts all symbols in the same row.
I didn't have that issue with C and I've found on stackoverlow a solution using strings & getline but I need it to be in "char" form.
How to actually read spaces and newlines? This is my current code for reading from file:
Code:
ifstream di("kocka.txt", ios_base::in);
char c[5000];
int br=0;
while( di >> c[br])
{
br++;
}
MessageBox(NULL, c, "Kocka", MB_ICONHAND);
di.close(); P.S kocka = cube (in croatian )
I'm unable to print out or return the inputted string modified.

//ch11_9.c

Basically, the task is to replace tabs with spaces, ensuring that the number of spaces is appropriate to get you to the next tab stop (i.e. if you were only 4 spaces away from a tab stop, don't replace the tab with 8 spaces).i've seen have included character arrays, and many have included multiple functions. I realize the text says "these exercises suggest programs of somewhat greater complexity than the ones earlie in this chapter," but it seemed like a very straightfortward task.Have i oversimplified or something?
Code:
#include <stdio.h>
#define TAB_STOP 8
int main()
{
int c, i;

i want to replace tabs with spaces but i didn't get it. I also tried to count all the chars that i read from a file but that does also not work.

int char_ = 0;

View 2 Replies View RelatedI want to store the address of a customer (with spaces) in a char variable (say cadd). First I tried to use "cin", as we know it reads until it sees any whitespace. So it reads only first word before a white space. So, I used "getline()" function. But when I used it, It didn't wait for the I/P (it skipped it).
char cadd[20];
std::cout<<"Enter Customer Address:
";
std::cin>>cadd;
std::cout<<"Enter Customer Address:

std::cin.getline(cadd,20);
