I read one csv file in which it contains different types of data like string, integer etc.I want to fetch only integer data from that file and store in vector.Below i copy some code that read line from file,store in vector.I tried to convert string to integer or double and do some operations on it as i know that string values,but how to identify only integer values and store that in vector?
#include<iostream>
#include<vector>
#include<string>
#include<fstream>
#include<sstream>
#include<iterator>
#include<algorithm>
using namespace std;
int main() {
string line;
int cnt=0,val1,val2;

input file like

write a c++ program that reads an unknown number of integer values and then print count, sum and average of odd values, even values, positive values, negative values!!
I am trying to read an array values from Tmin.txt file. I take array size from user viz. number of raw & column and then, read the following data from Tmin.txt file which look like this:
20 40 20 25 30
20 30 40 20 25
20 40 20 25 30
20 30 40 20 25
30 40 40 30 40
I am using getline, and then converting it to int by using atoi. But my code is not working.
Code : // reading a text file #include <iostream> #include <fstream> #include <string> using namespace std;
I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.
I am trying to get my program to calculate what point goes in what quadrant using a file. But msy program is not reading the values from the file and also it is not running so im not sure what's wrong with it.
//This program uses a fstream object to write data that will read the values of a (x,y) point from a file. //add the appropriate preprocessor #include <fstream> #include <iostream>
For an assignment I have to write a program which basically converts 8 bit binary numbers to ASCII and outputs the assembled text. Here's the catch:
The 8-bit binary numbers are provided by some external file (which only contains 8 bit binary numbers); the name and hence length is not known. The external file is called with a pointer upon execution
(./"conversion program" < external_file.in).
I'm getting the 8 bits as a string, calculate/convert decimals, output char type. HOW do I know when to stop the loop? If I just pick an insanely high number I get random stuff at the end; no boundaries obviousely lead to an infinite loop. Can I determine the lenght of this random ext file somehow nonetheless?
Is it possible to create a vector which dynamically adjusts itself until there are no more strings = end of the file?
I've been working on a homework assignment that randomly generates integers and populates them into an array (array1). The program is then supposed to:
1.) copy those values to a second empty array (array2)
2.) sort the values already in array1 (using an inline function)
3.) enqueue the unsorted integers from array2 into a heap vector
4.) a third empty array (array3) is supposed to be populated with those unsorted integers (by dequeuing them from the heap), sorted in reverse order.
But no matter what I do, I always get garbage values like these:
I've tried using both a standard random number generator:
array1[i] = rand()%100+1;
And the d_random.h file my instructor gave us, but nothing works.
Here's the code from all 3 files:
HeapTester.cpp
Code: #include <iostream> // Provides cin, cout #include <cstdlib> // Provides EXIT_SUCCESS, rand, srand #include "d_random.h"//Provides random number generator #include "Heap.h" using namespace std; // Use C++ Standard namespace //Elements in each array. const int arrayLength = 15;//100;
I'm trying to get my program to read a series of comma delimited values from a file into a vector. However, I am unsure how to actually go about doing this. I've posted my best guess below but it's really just a stab in the dark and I always receive a compiler error.
Im trying to swap the values of an integer and a character, however Im not sure where to insert the static_cast<type> part that I need for this to happen?
// Program to demonstrate a function template #include <iostream> using namespace std; // Interchanges the values of variable1 and variable2 template<class T> void swap_values(T& variable1, T& variable2)
I was just wondering whether or not it is possible to "mix" characters and integer values in a text document that is to be read by C.
I am to read and use values for length around the hip, neck and such, however, most of the tutoring examples I am finding online seem to strictly deal with either integers or characters alone.
Basically my text file looks a bit like:
Abdominal length: 90.000 Neck length: 26.500 and so on
So, before I move further into this subject, is it possible at all to isolate and use only the double values or will I have to format my text file differently?
this program is not giving to chance to enter the ooplevel value.
Code:
#include <iostream> using namespace std; const int SLEN = 30; struct student { char fullname[SLEN]; char hobby[SLEN]; int ooplevel; }; // getinfo() has two arguments: a pointer to the first element of // an array of student structures and an int representing the
how to carry out the conversions. The assignment is the normal hex to octal and Quart (base 4) via bit munipulation which I have worked out myself. However, I have been trying all day to figure out how to read in a string such as H1234, or O4567. How to parse the input I can handle the remainder myself. I'm just stuck and I've tried for hours.
I need to assign unique integer values to words in a dictionary that have the same alphabets, for example 'act' and 'cat' should have the same integer value. Would just adding the ascii values of the letters be sufficient?
I am trying to make my program read an integer until a space, namely ' ', is pressed, and then move on to the next command. However, all my attempts hitherto with both scanf() and getchar() have been to no avail. Every time it proceeds to the next command only upon pressing Enter, which is not quite what I want.
I have been working on some C++ code that doesn't seem to be going right. I'm wanting it to read a (three-digit) integer representing the value to be encrypted, a (one-digit) integer representing the encryption key, encrypt the value and print the encrypted value. The encrypting method used is that each digit in the given number is replaced by ((the sum of that digit plus key) modulo 10) then the first and last “encrypted” digits are swapped.
For example, if the number entered was 216 and the key given was 7, after applying the encryption procedure described the first digit (2) would become 9, the middle digit (1) would become 8 and the last digit (6) would become 3. The first and last encrypted digits are then swapped. The program displays the encrypted number: that is 389 in this case.
#include <iostream> using namespace std; int main() { int isolateDigits(); int replaceDigits(); int swapDigit1withDigit3();
