I have done an exercise from "Thinking in C++" to print text from a file to the console one line at a time, with the user pressing enter to get the next line.
My original code is below, how could I change it for one word at a time?
I tried to alter my program to print one word at a time by changing "getline(in, word)" to "in >> word", but it prints each new word on a new line, the only input I have found to make the next word appear is Enter, I assume that's why.
Is there a way to make it print one word at a time when the user says, but on the same line?
Basically I have a text file called words. I'm supposed to extract a word randomly form the file and have the user guess the word. If they guess the word correctly in x number of tries they will receive the definition.
I'm having trouble receiving that random word and I'm getting the definitions from the file.
This is what is in the words.txt file apple#the usually round, red or yellow, edible fruit of a small tree boat#a vessel for transport by water horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding television#a system for transmitting visual images and sound that are reproduced on screens soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc. bottle#a container, typically made of glass or plastic and with a narrow neck barber#a person who cuts hair toast#sliced bread browned on both sides by exposure to radiant heat radar#a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects red#of a color at the end of the spectrum next to orange and opposite violet
I'm writing a program that stores records into a file and then these records can be printed out. A last name, first name, and score is stored to be exactly 36 characters long (using leading spaces to pad) making it easier to retrieve specific records. For example, three records stored in the file would like like this: (the underscores are simply to illustrate the distance, they are not in the file itself)
When printed out, the names are formatted as follows:
lastname, firstname: 90 lname, fname: 100 last, first: 60
However, when I print them out this is what I get:
lastname, firstname: 90 lname, fname: 100$ last, first: 60H
For some reason, for any record after the first, an extra character is added to the end. These characters are not in the file, so I was thinking that the array for some reason wasn't being filled completely, (the array is initialized to size 36 and 36 characters are read from the file using fread) so it was printing out a random character assigned to the 36th array position. Except the character never changes, (always a $ for record 2, H for record 3, l for record 4 if i remember) and I've tried reducing the array size or the number of character read and it's the string that gets altered, the random character always remains. I figure the problem must be in the print_records function (appending seems to work no problem). Anyway here is my print records and appending records code.
Code: /* - Prints a single record stored in the file pointed to by ifp. */ void print_record(FILE *ifp, int record) {
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.
I'm learning programming, and C++. I've got a question, but I couldn't solve my problem so far. I need to use arrays and only basic stuff to solve this:
Create a program that reads a word from the user and then print (cout) this word on contrary. It's simple, I know, but I can't do it,. I've tried some stuff but I don't get how I will get the proper values to do this. All I know is that I can use variable.lenght().
I am reading a file then printing the data onto the other file. It is working, however when I check to see if each variable is being properly set after reading the file a issue arises.
Example of the file being read
Code: Vehicle PV50CAN passed camera 1 at 05:33:26. Vehicle W867BRO passed camera 1 at 05:33:29. Vehicle KQ63ARU passed camera 1 at 05:33:38. Vehicle K954ITQ passed camera 1 at 05:33:40. Vehicle V220MXB passed camera 1 at 05:33:42.
I've taken part the text into 1 word per line, but I can't figure out how to printf every word only once and then add (%d) in the end to show how many repetitions of that word there are.
Code: #include <iostream> #include <stdio.h> #include <stdlib.h> #include <string.h> using namespace std; int main(){ char *oneword;
The requirement is to capture statistics of uuid occurrences for ALIVE/SEARCH/BYEBYE (it can be all 3, combinations of 2 each, or one alone) in a dynamically populated file in run time.
I am able to print all 3 combinations, but not in combination of 1 or 2 e.g.
I want to generalize the code such that uuid occurrence does not have to be all 3 (ALIVE/SEARCH/BYEBYE), the occurrences can be any combination and code should work. e.g my code gives wrong results when input.txt contains the following:
these are the errors that I'm getting from an online c++ compiler
// main.cpp:4:10: error: #include expects "FILENAME" or // main.cpp: In function 'void permute(char*, int)': // main.cpp:17:9: error: 'f' was not declared in this scope
I don't understand how to print full_string to a file!// otherwise, I know that it gives the correct output -- 90 strings.
#include <string> #include <iostream> #include <fstream> #include >ios> // line 4 error using namespace std; char full_string[] = "112233";
[code]....
//iter_swap – it just swaps the elements pointed to by the respective pointers without changing the pointers themselves. so, it's basically equivalent to the function:
// min_element – finds the location of the minimum element that exists in the given range. in this case,
it is the char* pointer pointing to the location of that element. it can be implemented like:
char *min_element(char *start, char *end) { // end is 1 beyond the last valid element if(start == end) return end; // empty range char *min_pos = start; for(char *iter = start+1; iter != end; ++iter)
I am encoding some information in a binary file, and I want to check what I am doing by printing out all the bytes that represent the file.
This is being done by opening a pointer to the file with fopen, reading in each byte of data as a char, and then writing this char to the screen.
I have some image files (e.g. "image.jpg"), whose structure I know, so that I can test my program.
When I print out the chars, they are initially correct, and follow the structure of the file as expected.
However, after about 40 bytes, I find that every subsequent character is ' ' i.e. a blank character.
I then created a CharToBin function, which allows me to print out the actual bits in the char. When doing this, it shows that all the bits are 1 for the characters. i.e. most of the file is represented by 1's, which is clearly not correct.
This happens on all the image files I have tested, and furthermore, on several other non-image files. They all start printing out ' ' after a while. However, all these files are fine and not corrupted, e.g. the image files display correctly.
Code: #include <fstream> #include <iostream> #include <sstring> #include <string> #include <stdio.h> using namespace std; string CharToBin(char ch) { bool bits[8]; for (int i = 0; i < 8; i++)
I am trying to get the code to read from the txt file one bite at a time and then write this bite into the binary file but i cant seem to get it working.
FILE *fpcust, *fpcustbin; //<<<<<-----point to both sales and customers text files, and the new .bin files for both char buffer; int ch; int ch1; fpcust = fopen("c:customers.txt", "r"); //<<<<-----pointing to the file fpcustbin = fopen("c:customers.bin", "wb"); //<<<<<-----pointing to the new binary file, opening in writing binary
I have text (string) and I want to find a given word (it's ok!) and then insert another given word after the first word. The original string is beeing copied into a new string. But something is going wrong!!! Where is my mistake?
(I have some patches...)
Code:
#include <stdio.h> #include <stdlib.h> #include <string.h> //insert "new_word" after each occurence of "word" int main(){ char A[100]="In the sentence words the and the.";
How would one go about doing this? I am very fond with Windows I/O, but not so much with this subject. I am decent with fstream, probably not as skilled at it as I should be, but I assume <fstream> would be a better choice, since it isn't locked to Windows.
Anyway, say I have a .txt file like this:
Bill is a cow. Bill likes meat. Bob is a pig. Bob and Bill are friends.
And I want to count the number of times "Bill" is written. How would I do that?
I have a C++ program that performs calculations on numbers in a text file. However, suppose we have additional words in the text file such as "Title". In this instance, the program will not calculate the numbers in the file because of the text.
How do we remove text from a file using the C++ program? e.g. if I wanted to specify the program to remove any instances of the word "Title", how would I do it?
