C – Reverse Array

Program to reverse the array elements:

C program to read elements into array and display:

int main () {             int arr[5], i;             printf(“Enter 5 elements : \n”);             for(i=0 ; i<5 ; i++){                         scanf(“%d”, &arr[i]);             }             printf(“Array elements are : \n”);             for(i=0 ; i<5 ; i++){                         printf(“%d \n”, arr[i]);             }             return 0; }

C program to display array elements in reverse order:

int main () {             int arr[5] = {10, 20, 30, 40, 50}, i;             printf(“Reverse Array : \n”);             for(i=4 ; i>=0 ; i–){                         printf(“%d \n”, arr[i]);             }             return 0; }

C Program to find sum of array elements:

int main () {             int arr[5] = {10, 20, 30, 40, 50}, i, sum=0;             for(i=0 ; i<5 ; i++){                         sum = sum + arr[i];             }             printf(“Sum of Array elements : %d \n”, sum);             return 0; }

C Program to find average of array elements:

int main () {             int arr[5] = {10, 20, 30, 40, 50}, i, sum=0, avg;             for(i=0 ; i<5 ; i++){                         sum = sum + arr[i];             }             printf(“Sum of Array elements : %d \n”, sum);             avg = sum/5;             printf(“Average of array elements : %d \n”, avg);             return 0; }

C Program to display only even numbers in the array:

int main () {             int arr[8] = {8, 5, 1, 7, 4, 3, 2, 9}, i;             printf(“Even numbers of Array : \n”);             for(i=0 ; i<8 ; i++){                         if(arr[i]%2==0)                                     printf(“%d \t”, arr[i]);             }             return 0; }

C program to display the largest element in the array:

int main() {             int arr[8] = {7,2,9,14,3,27,5,4};             int large=arr[0], i;             for(i=1 ; i<8 ; i++){                         if(arr[i]>large)                                     large = arr[i];             }             printf(“Largest element is : %d \n”, large);             return 0; }
