Question:4
C Program to take input for “n” elements using an array. Pass the entire array to a function, Further print total number of -ve elements in the array.
Sol:

#include<stdio.h>
void show(int a[],int n)
{
	int i,p=0;
	for(i=0;i<n;i++)
	{
		printf("%d\n",a[i]);
		if(a[i]<0)
		p++;
	}
	printf("Total -ve elements = %d\n",p);
}
int main()
{
	int a[50],i,n;
	printf("Enter total elements ");
	scanf("%d",&n);
	/* input  */
	for(i=0;i<n;i++)
	{
		printf("Enter element ");
		scanf("%d",&a[i]);
	}
	/* to display elements */
	show(a,n);
	return(0);
}

/* Output */

Enter total elements 5
Enter element 25
Enter element -9
Enter element -35
Enter element 65
Enter element -12
25
-9
-35
65
-12
Total -ve elements = 3

Question:5
C Program to take input for “n” elements using an array. Pass the entire array to a function, Further print total number of even elements in the array.
Sol:

#include<stdio.h>
void show(int a[],int n)
{
	int i,e=0;
	for(i=0;i<n;i++)
	{
		printf("%d\n",a[i]);
		if(a[i]%2==0)
		e++;
	}
	printf("Total even elements = %d\n",e);
}
int main()
{
	int a[50],i,n;
	printf("Enter total elements ");
	scanf("%d",&n);
	/* input  */
	for(i=0;i<n;i++)
	{
		printf("Enter element ");
		scanf("%d",&a[i]);
	}
	/* to display elements */
	show(a,n);
	return(0);
}

/* Output */

Enter total elements 5
Enter element 25
Enter element 634
Enter element 45
Enter element 24
Enter element 3
25
634
45
24
3
Total even elements = 2

Question:6
C Program to take input for “n” elements using an array. Pass the entire array to a function, Further print total number of odd elements in the array.
Sol:

#include<stdio.h>
void show(int a[],int n)
{
	int i,e=0;
	for(i=0;i<n;i++)
	{
		printf("%d\n",a[i]);
		if(a[i]%2==1) /* if(a[i]%2!=0) */
		e++;
	}
	printf("Total odd elements = %d\n",e);
}
int main()
{
	int a[50],i,n;
	printf("Enter total elements ");
	scanf("%d",&n);
	/* input  */
	for(i=0;i<n;i++)
	{
		printf("Enter element ");
		scanf("%d",&a[i]);
	}
	/* to display elements */
	show(a,n);
	return(0);
}

/* Output */

Enter total elements 5
Enter element 25
Enter element 63
Enter element 42
Enter element 18
Enter element 69
25
63
42
18
69
Total odd elements = 3
