Computer Science homework question answer, step 1, image 1

 

Example by using the above given syntax:

 

Computer Science homework question answer, step 1, image 2

Here, int is the return type of function

abc is the function name

int a, int b, int c are the list of formal parameters.

Step 2

Consider the below given program code:

Sample program code:

 

 

#include <iostream>

using namespace std;

//function defination

//here a[] array is the formal parameter

//that is the copy of the original array

void addition ( const int a[3])

{

//declaring array

int i;

int add=3;

int c[3];

//for loop to add

for( i=0; i<3;i++)

{

c[i]=a[i]+add;

}

//for loop to display the array elements

cout<<"Modified array: ";

for( i=0; i<3;i++)

{

cout<<"  "<<c[i];

}

}

//main method

int main()

{

//declaring array

 const int a[3]={1,2,3};

//calling method

addition(a);

return 0;

}//end of main method
