I'm trying to pass these numbers into the array using the for loop: 1, 2, 3, 4, 5. I created two files in my project called "inStuff.txt" and "OUTPUTS.txt". I know I have an error at my input in the for loop, which is a bit similar to my problem or something? I'm also on linux using a crossGCC complier(not sure if that makes a difference).
#include <iostream> #include <fstream> 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 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?
#include <stdio.h> void define (int integer, int IntArr[0], int *IntP); int main(void) {int integer = 0, IntArr[1] = {0}, IntP = 0; define(integer, IntArr, &IntP);

Why does the integer with array change after passing trough the function and the normal integer doesn't? (I know why the normal one doesn't, but I dont get the array one)
I wanted to print the values of a array from a function by passing the array as well as the number of elements to be read. For a single dimensional array, this is how i have written it. It's pretty straight forward. I want to read 5 elements from the 5th element in the array.
Code: #include<stdio.h> void display(int array[],int size) { int i;
[Code]....
With this code I want to print the five elements from the element present in [0][4].
But shows an error that
Code: D:BennetCodeblocks CLearning CSingleDimentionalArray.c||In function 'main':| D:BennetCodeblocks CLearning CSingleDimentionalArray.c|18|warning: passing argument 1 of 'display' from incompatible pointer type [enabled by default]| D:BennetCodeblocks CLearning CSingleDimentionalArray.c|2|note: expected 'int (*)[10]' but argument is of type 'int *'| ||=== Build finished: 0 error(s), 1 warning(s) (0 minute(s), 0 second(s)) ===|
I know when you pass a array as an argument it gets decomposed into a pointer, but with a multi-dimensional array this is not the case. how this works for mult- dimensional array's?
This read a file (arrival time , brust time) for n processes and suppose to do shortest job first scheduling. the file read correctly but passing the value to SJF function gives read of 0's to all values .
#include<stdio.h> #include<stdlib.h> typedef struct { int brust_time[10]; int arrival_time[10]; }Time;
I'm working on a homework assignment that asks me to roll two die a user given number of times, find the roll sums, and a few other things. I'm working on it one module at a time and I'm running into two big problems so far.
The first problem is that my int variable rolls changes to a number within the random number generator range of numbers after I run rolldie. I got around this by making a const equal to the user entered value of rolls just so that I could continue developing the program.
My second problem is that the values of the arrays resultsOne[] and resultsTwo[] are changed after running findsum(). Why this is happening and I even tried passing them as const, but that changed nothing. We just started learning about passing arrays to functions, so there might be something big that I'm missing.
Code: #include <iostream> #include <cstdlib> using namespace std; void rolldie(int resultsOne[], int sizeOfresultsOne, int resultsTwo[], int sizeOfresultsTwo); void findsum(int resultsOne[], int sizeOfresultsOne, int resultsTwo[], int sizeOfresultsTwo, int tossSums[], int sizeOftossSums);
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;

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 want to count all the numbers in my text file (read.txt). Read text file consist of floating and integer number. Answer for the above file would be integer=2 and float =10.
in the following code how would i set a txt file up to where i can have say name = whatever in it and the program will find it and set it to the corresponding global value.
I have a report that's generated by a piece of software, and (I'm assuming because it was intended for Linux/Unix) when I open to read it in notepad, it has a bunch of funky symbols in it, and incorrect line feed characters instead of returns that windows uses.
I looked at the txt file with a hex editor and can see all the hex codes for the symbols I want deleted. One of the symbols 0A.
How can I do a "find and replace" command but do it with hex codes? These symbols cant be simply placed into my code file because VS does not know how to interpret it.
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'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 would like to extract and analyse the data but the data behind the NUL entry is not accessible for me maybe due to the fact that NUL normally marks the end of a line. Is there a method to remove the NUL entries in this text file?
I have chosen C# as our language . Students have to enter a name of a recipe, followed by the number of people it will serve, followed by a list of ingredients for a recipe. This, then, needs to be exported to a text file. This bit I am fine with.
They then have to import the file back into C# and recalculate for a new number of people. This is the bit I am struggling with. The calculation is fine, I can do that. The issue is getting it to loop around each column of data to not only perform a calculation (I have just set it up to multiply by an entered value for now). I have set up a text file with the following data in it:
I have to develop a C program that reads a very complex txt file (output of a calculation code, so full of mixed text and numerical tables), search for a specific table in it and individuate/print or replace a specific value with assigned position in the table.
5502 5202.3 1523 2536.1 1254 1256.2 17846 8956.2 and so on
left one is time and right one is pressure, I need to show the time value as it is but i need to use the pressure value to calculate air speed. I don't know how to use the strings to pick up the list properly. I did the calculation formula for the air speed but i can't pick the pressure value up from the text file. here's what i did:
#include <iostream> #include <fstream> #include <string> using namespace std;
There are 7 candidates and 365 votes in total. I need to do this using an array of structures. I need to read from a text file each of the names of the candidate and the number of votes they get. At the end i need to output the winner of the election.
Each candidate gets +1 vote for their number electionCandidate[0] for each one he gets one vote and so on for the rest. 365 voters in total.
I was able to input the name for each Candidate from the text file. Now the problem is putting each vote to the corresponding candidate. Also any vote that is above 7 is a spoilt vote which i am trying to count in the above code. The code compiles but it crashes.
I am using while(!feof) but it seems that its not working or this is not the correct way.
all i want to do is to read a fixed char array sized 4 from user and pass it to Binary File then Print Encrypted content from the the File to the console screen .. but it seems it prints the same input every time .. and i tried everything .. it works fine with integers and strings .. but when it come to char array nothing ..
#include <iostream> #include <fstream> #include <cstring> using namespace std;
