💻 Program Code

#include <stdio.h>
#define MAX 50
int main()
{
	int arr[MAX],n;
	int getdata(int *, int);
	void show(int *, int);
	n = getdata(arr, MAX);
	show(arr, n);
	return 0;
}
/* Function reads scores in an array. */
int getdata(int *a, int n)
{
	int x, i = 0;
	printf("\n Enter the array size\n");
	scanf("%d",&n);
    printf("\n Enter the array elements one by one\n");
	while(i < n)
	{
		scanf("%d", &x);
		*(a + i) = x;
		i++;
	}
	return i;
}
void show(int *a, int n)
{
	int i;
	for(i=0;i<n;++i)
	printf("\n %d", *(a+i));
}

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
