The program works, other than if I place the cursor below the last line in my merch file, the program outputs a line of garbage. The only solution I could find is to leave the cursor on the last line.
Code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
struct vRecord {
string venue, item;
float price;
[Code]...
This code works very oddly.
Code:
#include <algorithm>
#include <cstdlib>
#include <iostream>
[Code].....
private void open(object sender, EventArgs e) {
OpenFileDialog openDialog = new OpenFileDialog();
if (openDialog.ShowDialog() == DialogResult.OK) {
string[] lines = File.ReadAllLines(openDialog.FileName);
int k = 0;
while (k < lines.Length)
[Code] ....
So in this code, the user basically opens a text file from the dialog. Then the file gets read on all the lines and gets stored in an array. Now the reason I did this is because there are more fields of text boxes I have to fill in after I fill in the table (6x3). I'm getting an out of bounds error however.

This is a sample text file that is being used. As you can see all the lines from start up until (excluding "110") will be used in the table. Now I want to read the last lines in this text file and put it in another text box. How do I do that?
Code:
// Lab0Inventory.cpp : Starter lab
//Anastasia Glyantseva
#include "stdafx.h"
#include <fstream>
#include <iostream>
#include <iomanip>
#include <sstream>

I can't figure out why my makeString gets called first and the pString its called with contains garbage. I want my allocateMem to get called first, but my program is not going to that. What is wrong with the order of my code?
Saw a thread about a program to add an extra 'b' before 'B' in a file containing 'ABC'. I tried it. Here's my code:
("file1.txt" contains "ABC")
#include<iostream>
#include<fstream>
using namespace std;
int main(){
ifstream in;
ofstream out;
[Code] ...
It works except an extra C appears at the end.
O/P in the file:
"AbBCC"
I have been asked to write a program to grade several multiple-choice exams. The exam has less than 80 questions, each answered with a letter in the range of ‘a’ through ‘f’. The data are stored on several files such as exam1.dat where the first line is the key, consisting of a string of n characters (0<n < 80). The remaining lines on the file are exam answers, and consist of a student ID number, a space, and a string of n characters.
The program should have a while loop in the main routine to ask users input a data file name through keyboard. In this way, the program has a capability of repeatedly asking for a new data file in each while loop until users input a key word “exit”. Once “exit” is encountered, the while loop terminates and your program ends. A typical input exam data file (exam1.dat) looks like:
abcdefabcdefabcdefab
1234567 abcdefabcdefabcdefab
9876543 abddefbbbdefcbcdefac
5554446 abcdefabcdefabcdef
4445556 abcdefabcdefabcdefabcd
Apply strlen( ) or the length( ) of string to the first line of the above data file for determining the number of questions in the problem. If a student gives more answers than necessary, the extra answers will be automatically truncated. On the other hand, if a student provides less number of answers, the remaining unanswered questions are considered as being answered wrongly.
After users input an exam data file, your program should ask users to input another grade-curving file name (e.g., gradeCurving.dat). This second file contains the information to convert a percentile score to a curved grade in levels of ‘A’ through ‘E’. For instance, a grade-curving file takes the following format: a curved alphabetic grade, a space, a percentile grade served as marker.
A 90
B 80
C 70
D 60
E 50
The above information means that ‘A’ = 90 through 100; ‘B’=80 through 89; ‘C’=70 through 79; ‘D’ = 60 through 69; “E”=50 through 59; For the remaining grades, you can assign an ‘F’.
Furthermore, in each while loop in the main routine, your program should ask users to input an output file name such as score1.dat. The output file will store the scores for each student in a format: student ID number, a space, a percentile score, and a curved grade in ‘A’ though ‘E’. The program should also compute and display the following statistics for the graded answers: Average score, Maximum score, and Minimum score.
A typical output on a data file looks like:
1234567 90% A
9876543 85% B
5554446 95% A
4445556 75% C
5551112 80% B
Statistics:
Average Score: 85%
Minimum Score: 95%
Maximum Score: 75%
This Is what I have so far. It compiles fine and everything but when I input the files it says "There was an error opening the corresponding files. Check input name perhaps?" and it exits out ....

A program that outputs all numbers divisible by both 5 and 6.This is what i have written :
#include<stdio.h>
int main () {
int i=200;
int b=10;
while(i<1000)
i b/6%==0
}
where could i have gone wrong.
a program that allows the user to enter a statement and outputs statistics; number of vowels, number of constants, percentage of vowels and constants, number of words, number of punctuation characters
View 2 Replies View RelatedI need to do a code that gave me Original string, uppercase string, lowercase string, reverse string (if letter is upper then convert to lower, and if lower then convert it to upper) and uppercase first (first character of each word in uppercase).
I need to do it in functions but i dont know hot to use strings. The program should provide the option to save the outputs in a file.
For class I need to write a program that inputs a file (the dividend), performs binary division on the file (using 0x12 as the divisor), and outputs the remainder(checksum).
I have researched binary division algorithms and I get the general gist, but I'm still unsure where to start. How would I store the dividend and divisor? As two arrays of bits?
Then, I need to figure out how to perform shifts and XORs on the the binary numbers. Maybe I should use bitwise operations?
I seem to be missing a concept or 2 here ... I am tasked with writing a program that reads text from a file and outputs each line to the screen as well as to another file PRECEDED by a line number ...
In addition, I have to Print the line number at the start of the line and right-adjusted in a field of 3 spaces ...
Follow the line number with a colon then 1 space, then the text of the line.
Another kicker, is I have to grab the data 1 character at a time and write code to ignore leading blanks on each line.
Here is what I have so far:
#include <iostream>
#include <conio.h>
#include <fstream>
#include <string>
#include <cstdlib>
#include <cctype>
using namespace std;
int main() {
char next;
int count = 0;

This program must take user input(from stdin) that contains both a number and then a punctuation character, either a single quote(') or double quote(") that specifies feet or inches. It keeps prompting the user to enter a length until the user enters the sentinel value of 0. For example:
Enter a measurement and unit: 1'
Enter a measurement and unit: 2"
Enter a measurement and unit: 0
Total: 14 inches
The ultimate goal of this program is to then write an Assembly language program that is structurally similar and makes use of these 4 functions:
void printStr(char *)
Arguments:
edi = address of null-terminated string to print
Returns:
Nothing
[Code] ...
So here is what I have:
int main() {
char value[50];
char *end;
int sum = 0;
long conv;
while(conv !=0)
[Code] .....
I was told to use fgets instead of scanf for for stdin to parse the number and the quotation marks. I think I converted the number from string to integer correctly with strtol, but I really do not know how to obtain the (") or (') from user input so the program knows whether to convert the number to feet or just inches. No matter what I type in, even if it's without a quotation mark, it still multiplies the number by 12. In the IF and ELSE IF statement, it should state
if(value = ''')
and...
else if(value = '"')
I am working on a program that deletes same lines in a text file. I already wrote it, but it still doesn't work.
Code:
#include <stdio.h>
main(){
FILE *f1,*f2;
char oneword[100],filename[25];
int c;
long int i,j;
char *norstring[500000]; /* I count from 1 */
[Code] ....
how could this program tell the ID's and Passwords of more than one line in the text document?
# include <stdio.h>
# include <conio.h>
# include <stdlib.h>
# include <string.h>

So I am writing a program that counts the letters of 3 lines of input from the user. I am using a 3 x 80 character array as the "notepad". Upper and lower case characters are incremented on the same counter array.
Code:
/*Letters in a string*/
#include <stdio.h>
#include <string.h>
#include <ctype.h>
void countAlphabet(char *);
/*Character counting array*/
int alphabet[26] = {0};
[Code]...
My program does compile and counts the number of lines of code, which is LOC: 20. My issue this, according to my code instruction it should not count comments (//) and also shouldn't count blank lines of code. Unfortunately my code is counting // and white space.
What seems to be working is #, all three includes are not being counted. That’s a good sign. I’m using the same technique not to count #. Why isn't working for comments and blank lines? I’m pretty sure that my logic is correct. I think my problem is maybe syntax.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
//read my file

I have a .txt file that contains, together with a few characters, columns of values that I want to save in different files like is written in the program (file 1, file2, file3 - a with x, b with y, c with z). The pattern of the source text file is like this:
known_vector frame1 151 65 0 frame2 151.000763 64.538582 0.563737
known_vector frame1 152 65 0 frame2 152.000702 64.542488 0.560822
known_vector frame1 153 65 0 frame2 153.000671 64.546150 0.558089
Until now I could manage to split the files, but the output gives me only zeros. First the program count the number of lines of the read text file, then it should display the desired columns of double values in three other .txt files.I've got for the three .txt files columns like this:
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
So I need to make a program that counts the number of words, lines, and vowels in a program. Punctuation and white spaces are not counted in any of the counts. I have this so far and the words, and lines work and are correct but I can't seem to get the vowel count to work.
#include <iostream>
#include <fstream>
#include <cmath>
#include <cstdlib>

I'm making some progress. My program does compile and output the number of line per code, but it shouldn't count comments and blank lines. I tried using (s.substr(0,2) == "//") as suggested but it didn't work.
This is my improved code:
Code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
const int A = 3;
int main() {
string s;
[code].....
C program to count the number of lines in a text file and reverse the contents in the file to write in an output file.
ex :
input
one
two
three
output:
three
two
one
Code:
#include <stdio.h>
main() {
int c, n1;
n1 = 0;
while ((c = getchar()) != EOF)
if (c == '')
++n1;
printf("%d", n1);
}
I have a more complicated program I'm wishing to have display the output, however, to save some time I'm using an example of a shorter version. count the lines in input and display the output in terminal when ./program is executed after compilation. To count and compute lines, words and within arrays.
Using cin.sync() works great so far, but my program still breaks if you copy something with multiple lines into the console.
string test = "";
while(true) {
cin.sync();
getline(cin, test );
cout << endl << "test: " << test << endl;
}
However, if you were to copy this:
1
2
3
and paste it into the program, the output would be1
2
3
test: 1
test: 2
And if you press enter one more time:1
2
3
test: 1
test: 2
test: 3
The 3 finally pops out.
So i have this code:
if (get_brick_at(Position(row, column)) == NULL)
Where get_brick_at is defined like this:
>Brick& get_brick_at(const Position & p) {
return board[p.get_row()][p.get_column()];
}
Now, of course this does not work since the compiler cannot convert from long int to a Position. So how do i know if the return value of get_brick_at is garbage?
I also have a couple of other situations where i want to return some kind of NULL-like value under certain circumstances.
My question is: How do i handle situations like that?
Im programming client/server app that client provide the file name then the server send it to client then the client will save it ..this is part of code in client
Code:
char buffer[1024];
printf("FIle is being downloaded ...
");
printf("%s
",buffer);
}
[code],...
So i have 2 problems ::
1st one is when i write to file the file permission i cant define it with data type mode_t ,so the file does not open at all after creation...
2nd one is: the data in buffer is less than 1024 ,the data wrote to buffer but with garbage data . How to make the file read only the real data with garbage ??
