Write C code to reverse the contents of the array.For example, [1,2,3,4,5] should become [5,4,3,2,1] : - Ans : #include<stdio.h> int main() { int arr[20], limit, i; printf("Enter Limit:\t"); scanf("%d", &limit); printf("\nEnter %d Elements in 1-Dimensional Array\n", limit); for(i = 0; i < limit; i++) { scanf("%d", &arr[i]); } printf("\nArray Elements\n"); for(i = 0; i < limit; i++) { printf("%d\t", arr[i]); } printf("\nReverse of Array\n"); for(i = limit - 1; i >= 0; i--) { printf("%d\t", arr[i]); } printf("\n"); return 0; }
