Write C Program to Reversing an Array Elements in C Programming

#include<stdio.h>

int main() {
int arr[30], i, j, num, temp;

printf("\nEnter no of elements : ");
scanf("%d", &num);

//Read elements in an array
for (i = 0; i < num; i++) {
scanf("%d", &arr[i]);
}

j = i - 1; // j will Point to last Element
i = 0; // i will be pointing to first element

while (i < j) {
temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
i++; // increment i
j--; // decrement j
}

//Print out the Result of Insertion
printf("\nResult after reversal : ");
for (i = 0; i < num; i++) {
printf("%d \t", arr[i]);
}

return (0);
}

Enter no of elements : 5
11 22 33 44 55
Result after reversal : 55 44 33 22 11
