Apr 10, 2018 · To swap elements of two arrays you have to swap each pair of elemenets separatly. And you have to supply the number of elements in the arrays. Otherwise the arrays need to have a sentinel value. Here is a demonstrative program …

void swap(double *array, int a, int b) { double temp = *array[a]; /* <- it's a double */ *array[a] = *array[b]; *array[b] = temp; } And to call it, this. swap(double array[0],double array[2]); should be. swap(array,0,2); finally, if you prefer, pass in two pointers with the temp variable and call it with swap(array[0], array[2]),

Swapping is done using pointers. 1. Declare an array and define all its elements. 2. Create a function with two parameters i.e. two pointer variables. 3. Inside this function, first create a temporary variable. Then this temporary variable is assigned the value at first pointer. 4. Now, value at first pointer changes to the value at second pointer.

Aug 26, 2022 · Given an array arr[], the task is to rearrange the array elements by swapping adjacent elements such that no element remains at the same position after swapping. Examples: Input: arr[] = { 1, 2, 3, 4, 5 }

For the swap_arrays() function, here’s what I concocted: void swap_arrays(int *y, int *z) { int x,temp; for(x=0;x<SIZE;x++) { temp = y[x]; y[x] = z[x]; z[x] = temp; } } All you need to swap elements is a temporary storage int variable, temp. The value of y[x] element is saved to temp.

Same program by using pointers. #include void swap(int *, int *); main() {int a[10],b[10],i; printf("Enter First array->"); for(i=0;i<10;i++) scanf("%d",&a[i]); printf("\nEnter Second array->"); for(i=0;i<10;i++) scanf("%d",&b[i]); for(i=0;i<10;i++) swap(&a[i], &b[i]); printf("\nArrays after swapping"); printf("\nFirst array->"); for(i=0;i<10;i++)

Nov 27, 2017 · Below is the step by step descriptive logic to swap two arrays using pointers. The logic is same for same or different length of arrays. Input array elements in two arrays say sourceArray and destArray. Initialize a pointer to both arrays say *sourceArr = sourceArray and *destArr = destArray.

Aug 7, 2012 · I am trying to write a program that 'given a list (array) of 10 integers, find the one with the smallest absolute value and swap its position with the last one and output the new list. Here's what I have coded but its not swaping.. int array[10]; int arraynew[10]; int absmallest = 0; int index = 0; int i; for (i = 0; i < 10; i++) {

Oct 1, 2009 · I'm trying to write a function to swap 2 elements in a 2D array: void swap(int surface[][], int x1, int y1, int x2, int y2) { int temp = surface[x1][y1]; surface[x1][y1] = surface[x2][y2];...

Dec 22, 2022 · This C program demonstrates how to accept an array of elements and swap the elements at desired positions using pointer. Before going into the program, we need to know more about pointers in C, and how this swapping of elements in …
