C Program to Read integers into an array and Reversing them using Pointers
#include<stdio.h>
#include<conio.h>
#define MAX 30
void main() {
int size, i, arr[MAX];
int *ptr;
clrscr();
ptr = &arr[0];
printf("\nEnter the size of array : ");
scanf("%d", &size);
printf("\nEnter %d integers into array: ", size);
for (i = 0; i < size; i++) {
scanf("%d", ptr);
ptr++;
}
ptr = &arr[size - 1];
printf("\nElements of array in reverse order are :");
for (i = size - 1; i >= 0; i--) {
printf("\nElement%d is %d : ", i, *ptr);
ptr--;
}
getch();
}
Enter the size of array : 5
Enter 5 integers into array : 11 22 33 44 55
Elements of array in reverse order are :
Element 4 is : 55
Element 4 is : 44
Element 4 is : 33
Element 4 is : 22
Element 4 is : 11
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.
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.
