Question

divide even number by 2 and what is the reminder?

duvid odd number by 2 and what is the reminder?

here modulus is a remiander function.

MY_ARRAY[] is an array if 49 elements or DINT[49]. Create four versions of structured text code that sets all even elements of MY_ARRAY[] =3 and all odd elements = 7 using. You can use any function or construct in structured text however each version will contain only 1 type of loop construct:

1) 1 While loop, 1 Repeat loop , 1 For loop incrementing by 1 and 2 For loops, each incrementing by 2

Hint, the modulus function may help for even/odd numbers.

Answer 1

• When you divide an even number by 2, the remainder is 0.
• When you divide an odd number by 2, the remainder is 1.
• A number is identified as even number when the number is divided by 2 leaves remainder as 0.
• A number is identified as odd number when the number is divided by 2 leaves remainder as 1.
• Modulus is the remainder function in most of the programming languages.
• Modulus is denoted by '%'

Code Without Snippet Using One For Loop:

#include <iostream>

using namespace std;

int main()
{
// Declare the array of size 49
int my_array[49];
  
// Initialize the array. Initialising with consecutive numbers
for(int i=0;i<49;i++)
{
my_array[i]=i;
}
  
// Printing the array before changing
cout<<"Before Changing: "<<endl;
for(int i=0;i<49;i++)
{
cout<<my_array[i]<<" ";
}
  
// Using One For Loop
// Now Replacing every even number with 3 and Odd with 7
for(int i=0;i<49;i++)
{
// Checking if the element is Even
if(my_array[i]%2==0)
{
my_array[i]=3;
}
  
// Checking if the element is Odd
else
{
my_array[i]=7;
}
}
  
cout<<endl;
  
// Printing the result after changing
cout<<"After Changing using For Loop: "<<endl;
for(int i=0;i<49;i++)
{
cout<<my_array[i]<<" ";
}

}
