Answer to Question #259634 in C++ for jye

Question

Write a function that categorizes negative and positive numbers of a given innial array into two separate arrays with sufficient allocated array space. Write the main program using the upper function in two cases:

The input array is a static array with the value of the given elements.

The input array is a dynamic array with the value of elements entered from the keyboard

Displays two arrays of results to the screen.

Answer 1

#include <iostream> 
#include <string> 


using namespace std; 


void categorizesNegativePositiveNumbers(float innialArray[],int size){
	float positiveNumbers[100];
	int positiveNumbersSize=0;
	float negativeNumbers[100];
	int negativeNumbersSize=0;


	for(int i=0;i<size;i++){
		if(innialArray[i]>=0){
			positiveNumbers[positiveNumbersSize]=innialArray[i];
			positiveNumbersSize++;
		}else{
			negativeNumbers[negativeNumbersSize]=innialArray[i];
			negativeNumbersSize++;
		}
	}
	//Displays two arrays of results to the screen.
	cout<<"All positive numbers:\n";
	for(int i=0;i<positiveNumbersSize;i++){
		cout<<positiveNumbers[i]<<" ";
	}
	cout<<"\nAll negative numbers:\n";
	for(int i=0;i<negativeNumbersSize;i++){
		cout<<negativeNumbers[i]<<" ";
	}
}


int main(){ 
	//The input array is a static array with the value of the given elements.
	float staticArray[]={-54,4,44,87,56,-23,66,50,-8,-48};
	categorizesNegativePositiveNumbers(staticArray,10);
	//The input array is a dynamic array with the value of elements entered from the keyboard
	int size=-1;
	cout<<"\n\nEnter the number of elements in the dynamic array: ";	
	cin>>size;
	float* dynamicArray= new float[size];
	for(int i=0;i<size;i++){
		cout<<"Enter the element "<<(i+1)<<": ";
		cin>>dynamicArray[i];
	}
	categorizesNegativePositiveNumbers(dynamicArray,size);
	delete[] dynamicArray;
	cin>>size;
	return 0;
}
