Answer to Question #216993 in C++ for Srikanth Kodamasim

Question

Create a file called "DATA" to store the set of integer elements. Search whether the given element is present or not within the file. If the element is present, then write the factors of that searching element in the "FACTORS" file. Write a formatted IO file program to demonstrate the above operation and display the contents of "FACTORS" file.

Answer 1

#include<iostream>
#include<fstream>
using namespace std;


int main(){
	int arr[10] = {90,100,200,400,40,60,80,30,60,70};
	ofstream file("DATA.txt", ios::out);
	for(int i=0; i<10; i++){
		file<<arr[i]<<endl; //Writing the set of integers to the file
	}
	file.close();
	ifstream file1("DATA.txt", ios::in);


	int arr1[10];
	for(int i=0; i<10; i++){
		file1>>arr1[i]; //Putting the content of the file in the array
	}
	
	for(int i=0; i<10; i++){
		cout<<"The element1  is\t"<<arr1[i]<<endl;
	}
	file1.close();
	int given_element = 400; //400 is the given element but any element can be searched
	ofstream file2("FACTORS.txt", ios::out);
	
	for(int i=1 ;i<10; i++){
		if(arr1[i] == given_element){
			for(i=0; i<given_element; i++){
				if(given_element % i == 0){
					file2<<i<<"\n";
				}
			}
		}
	
	}
	
	file2.close();


	ifstream file3("FACTORS.txt", ios::in);
	int arr2[10];
	for(int i=0; i<10; i++){
		file3>>arr2[i]; //Writing the set of integers to the file
	}
	file3.close();
	for(int i=0; i<10; i++){
		cout<<"The element is\n"<<arr2[i]<<endl;
	}
}
