Question

Need help with number 1, mainly about setting up an array with the numbers from an input file.

In C++ specifically

This is an example of an input file, the first number is the size of the array and the others are the values to be put into the array. I need to set this up so it could fit any type of size a user could choose for the array so not just this example specifically.

Explanation / Answer

Please find below code to create an array dynamically from a file.:

#include <iostream>

#include <fstream>

using namespace std;

Void main(){

int size;

int *array; //creating array as pointer.

int i;

ifstream input (“cl_test.txt”); // Replace file name with desired file name

input >> size; // First value is treated as size of an array

for (i = 0; i < size; i++) {

input >> array[I]; // taking input from file one by one and storing the same in array

}

   input.close();

cout << “Array is:”<<endl;

for (I = 0; I < size; i++) {

cout << array [i] << endl;

}

}
