QUESTION 1d.

, PROGRAM.
#include <iostream>

using namespace std;

const int LIMIT =10;

int main()

{



float counter;

//The declaration of variables can be on the same line separated by a comma.

int number, zeros, odds, evens;

//The counter variables are inirialised to assure that they don’t acquire an unknown initial value.

zeros=0;

odds=0;

evens=0;



cout<<"Please enter "<<LIMIT<<" integers, positive,negative or zeros."<<endl;

cout<<"The number you entered are "<<endl;

for(counter=1;counter<=LIMIT; counter++)

{

cin>>number;



switch(number%2) //The switch statement is working on a remainder and (%) is used.

{

case 0:

evens++;

if (number==0) //correcting the boolean operator for number is equal to zero…(==) not (=)

zeros++;

break;
