Numeric Array and Functions

Question:1
C Program to take input for “n” elements using an array. Pass the entire array to a function and display all the array elements.
Sol:

#include<stdio.h>
void show(int a[],int n)
{
	int i;
	for(i=0;i<n;i++)
	{
		printf("%d\n",a[i]);
	}
}
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 10
Enter element 20
Enter element 30
Enter element 40
Enter element 50
10
20
30
40
50

Question:2
C Program to take input for “n” elements using an array. Pass the entire array to a function, Further calculate and print their sum of all the elements.
Sol:

#include<stdio.h>
void show(int a[],int n)
{
	int i,s=0;
	for(i=0;i<n;i++)
	{
		printf("%d\n",a[i]);
		s=s+a[i];
	}
	printf("Sum = %d\n",s);
}
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 10
Enter element 2
Enter element 6
Enter element 32
Enter element 14
10
2
6
32
14
Sum = 64

Question:3
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 10
Enter element -96
Enter element -3
Enter element 5
Enter element 97
10
-96
-3
5
97
Total +ve elements = 3
