The elements of 2-D array can be accessed with the help of pointer notation also. In C an array is not a single "thing" you can swap. Example: Input: Input first array: 100 330 30 40 50 60 70 80 90 10 Input second array: 10 9 8 7 6 5 4 3 2 1 Output: First array after swapping: 10 9 8 7 6 5 4 3 2 1 Second array after swapping: 100 … Write a function which takes two arrays as parameters (assume both arrays have the same size). Now create a function passing two pointer variables of float type as parameters to this function. Read the elements of the two arrays and print them after swapping using pointers. For example, if the array is [1,2,3,4,5,6], after swapping it will become [2,1,4,3,6,5]. /** * C program to swap two arrays using pointers */ #include #define MAX_SIZE 100 // Maximum array size /* Function declarations */ void inputArray(int *arr, int size); void printArray(int *arr, int size); void swapArray(int *sourceArr, int *destArr, int size); int main() { int sourceArr[MAX_SIZE]; int destArr[MAX_SIZE]; int size; // Input array size printf("Enter size of array: "); scanf("%d", &size); // Input elements of destination array … Then, the value of the first variable is assigned to the second variable. C > Pointers Code Examples. C program to swap two strings, i.e., their contents are interchanged. If we want to swap two arrays, then we have to swap the data. Inside a function a variable temp is declared of float type, which will store the value pointed by first pointer variable. Arrays are closely related to pointers in C programming. By the way, data [0] is equivalent to *data and &data [0] is equivalent to data. Pointers with 1-D arrays: An array variable name itself represents a pointer to the first element of that array.
