I'm a basic C++ programmer, and I am stuck on this problem. You work for a company that collects a set of numbers. The numbers are located in a data file named "./Data_File". The data file contains two columns. how do you count a certain number on the left column.
#include <windows.h> int main() { int i; int y=6; int x=9; gotoxy(x,y); //gotoxy(x,y) must be the coordinate that the number lies in.

How to make this program that the output is a number that counts up to infinite (or we say just like a timer but there's no minute just all whole number counting up ) using for loop ? and when the number changes it also change in color ! and the color of a number is according to the color attribute of console output.
I am unsure how to write a function which modifies the content of the 1D character array and counts the number of the vowels. the following is the array that i have.
I have recently hit a stump with C++ and have been getting pretty frustrated with this assignment. I just can't seem to find out how to start the assignment. Basically for the first part of the assignment, I need to find the number of characters in this .txt file my teacher provided for me. The only exception is that I can only count the actual letters themselves, not spaces or punctuation. How would I go about doing this? I have read about functions like isalpha but can't figure out on how to fit them into code to do the first part of this assignment.
it looks like a popular method for determining the total lines in a file is to read the entire file character by character in search of ' '. I have a file with 5 lines, but for some reason this code isn't finding any instances of ' '. Is this possible? Is there a better way to get the number of lines in a file?
The file looks like this:
Code: NAME: John FRIEND 1: Steve FRIEND 2: Andrea FRIEND 3: Ken OCCUPATION: Programmer
I'm trying to write a program and I'm stuck. In order to continue on I simply need to know if there is a way of counting how many times the remainder of some number n when divided by some number x is 0.
For example
int lockers, i; cin>>lockers; //how can I count the amount of occurrences where lockers%i==0 while i<=lockers
A bit hard for me to articulate so let me know if it's unclear.
I was trying to make a function that would return how many lines are in a certain file. I was looking at [URL] which talks about how to count how many characters are in a text file. I just want the number of lines with in a file.
I am trying to write a function that will count the number of distinct values in an array of N size and return that number. For example array a[n] = {1, 2, 3, 1, 2, 3, 1}. My code won't look exactly like this because I am using an array that can be modified by user input. it is part of a bigger program that will also has a function for finding the Equilibrium Index for that same array. This is what my Code looks like:
void findDistinctValues() { int t = 0; int j = 0; int disValue = 0; for( i = 0; i < arraySize; i++) {
[Code] .....
This function works but the problem is it returns 16, or the number of times that the number being compared does not equal the one it is being compared to. how do I get it to only return the number of distinct values? The data set mentioned above is what I am using for input data so it should only have 3 values.
I'm trying to copy a file into another file and copy the number of characters copied but my while loop doesn't even enter into a loop indicating the file is already at the EOF file character. I've confirmed this by placing the printf() statement inside the while loop, which doesn't print anything and by keeping it out of the while loop and changing the chars_copied to something like 9, it prints 9 for number of chars_copied. I don't understand why the file is already at the EOF character, I've tried this with a few more files, it's the same result.
Code: #include <stdio.h> int main(void){ FILE *input_file, *output_file; int c, chars_copied=0;
if((input_file=fopen("C:workmarks.txt", "r"))==NULL) perror("input file open failed");
How can i count total number of each topic separately? For example total number of topic 1 between all nodes. To begin enter 10 and 7 to initial node number and number of topic.
I've been struggling with this for a while, I have to write a function that accepts a word (in my case the word is "the") and file pointer, and counts the number of times the given word appears (case insensitive) within the file associated with the pointer. This means the two words "the" and "THE" should both be counted.
Here is my code:
int WordCount :: countWords(string wrd) { int counter=0; string temp = ""; while (getline(*file,temp)) { for (int i = 0; i < temp.length();i++) {
[Code] ....
This is what I have come up with, but I get an incorrect value. It was suggested to us to consider using the strcpy() or strstr() functions, but I don't know how to use them.
Ok, so I am writing this program with 10 different functions, and one of those functions needs to count how many times 0 appears in a text file. I've done this before, but I am so stumped right now. Should I get the numbers from the 2d array I have, or should I just use the text file here? Here is what I have right now:
int toursMissed(int scores[][COLS]){ int counter; for(counter=0;counter<=96;counter++){ if(scores==0){ counter++; return counter; } }

So I'm trying to count the number of lines in a text file that is inputted by the user. Also the code doesn't sum up the last number of the text file (exmp it calculates and print only 14 from 15 numbers). I'm a beginner in c++ programing.
I'm creating a program to read information about class schedules at my school, reformat the information, and allow the user to search for specific semesters. There are eight fields of information. I'm reading the info from a text file using eight parallel arrays, but I'm having trouble declaring the arrays. I can run this code in one compiler (Dev-C++) with no problems, but I get errors when trying to compile it using Visual Studio stating that arrays must be declared with a constant value. I have a loop to run through the text file, with a counter to increment with each subsequent line, then I create a constant int equal to the counter, and declare the arrays of size equal to the constant int. Here's the section of code in question:
// Counting the number of lines in the text file inFileForLines.open("CIS225HW1DA.txt"); string countLine; int numberOfLines = 0; //Discarding the first line of the text file containing only column headings getline(inFileForLines, countLine);
I'm attempting to pass a couple of variables over to my Item.cpp class, that is description and item_price. However under item.set(description,item_price), i get three errors. One under the . (period) saying : expected an identifier and two more under description and item_price stating that variable " xxx " is not a type name.
Main.cpp
#include <iostream> #include "item.h" using namespace std; using namespace items; int main(){ int n;
So I have a template, part of a larger code, that is designed to calculate the number of multiplications it took to reach a certain number. The problem is, whenever I execute the program, mults is always printing out a strange number, perhaps its actual address.
template <class T> T power3(T x, unsigned int n, unsigned int& mults) { if (n == 0) return 1; if (n == 1) return x; if (n == 2){
I have code already and am looking to incorporate something new into it. I am trying to specify a bit size. A snippet of something similar I have is,
Code: //header.h int x; Code: //main.cpp int func1(int a) { x = a; }
Is there anyway I can recast the variable x into another type? For example, if func2 had a char parameter instead, can I somehow make x become char type?
I just compiled some code I've been working on at a different OS/compiler and realised that Code: sizeof(unsigned long) returns 4 in one pc and 8 in another.
I've heard that bytesize conventions for basic variables were not particularly "universal" before but this is the 1st time I've had a problem with it.
how do I make a typedef that clearly indicates to whatever compiler compiler I want u32 to be an 32bits unsigned and u64 to be 64bits?
I have two char variables, m_GPSOffset[13] and m_FileName[100]. When m_GPSOffset has a value assigned to it, say for instance +11:25:30. The first entry of the value, in this case +, is always stored in m_FileName. I am clueless on why this is occurring.
The code below is supposed to be a program that allows the user to enter in 2 matrices and add them together, and gives an error when they're not the same dimensions.
The error I'm getting is on line 11 of MAIN.CPP and is saying "The Variable has incomplete type 'Matrix'".
MAIN.CPP
#include <iostream> #include <vector> #include <string> #include "Matrix Class Input.h" using namespace std; int main() { Matrix A,B,C; int r,c=0;
