Arrays and Functions

Question

Write a C program using a function called find_divisible_by_2() that gets an array and prints the elements of that array which are divisible by 2. Assume that the size of the array is 10.

Here is the function declaration/prototype: void find_divisible_by_2(int a[],int size);

Sample Run:

Enter array’s elements: 10 15 4 1 20 54 6 79 15 63

Elements divisible by 2: 10 4 20 54 6

Answer 1

#include <stdio.h>

#define MAX (10)

void find_divisible_by_2(int a[],int size)

{

int iLoop=0;

printf(" Elements divisible by 2:");

for (iLoop=0; iLoop<size; iLoop++)

{

if (a[iLoop]%2==0)

{

printf("%d ",a[iLoop]);

}

}

printf("\n");

}

void input_array(int a[],int * size)

{

int iLoop=0;

int rspAgain=1;

for (iLoop=0; iLoop<MAX; iLoop++)

{

printf("Input integer value # %d :>",(iLoop+1));

scanf("%d",&a[iLoop]);

rspAgain=-1;

while (rspAgain!=0 && rspAgain!=1)

{

printf(" another ??? (1 = YES 0=NO ) :>");

scanf("%d",&rspAgain);

}

if (rspAgain==0) { break; }

}

*size = iLoop+1;

}

main()

{

int A[MAX];

int N;

input_array(A,&N);

find_divisible_by_2(A,N);

}
