Can anybody tell me methods about how to pass a 2d array to a function in c language?

• please tell me about function prototype if i have to pass a pointer to array related with a 2d array.which is best method to pass a 2d array to a function?

• Answer:

  arrays in c are really just pre allocated pointers. You have a couple ways you can pass them to a function. you can declare your function to accept a 2d array void myFunct(int array[5][5]); to call it -- int myArray[5][5]; myFunct(myArray); think of an array of integers as a pointer that points to the first integer in the array. when you use an index [ ] you are just telling it the offset from the starting pointer. so you declare an int x[5] array x would be a pointer essentially. if you want to access the third int x[2] that is telling the compiler take the pointer x (a memory location and add the size of integer * 2 to it. Basically it is just pointer math but the compiler does it for you to prevent memory leaks and helps prevent access of non-allocated memory. you can actually allocate something dynamically and access with the array [] index feature. int *x; //pointer of type int //allocate a dynamic array of 5 ints x = (int*) malloc(sizeof(int) * 5); x[0] = 1; //is the same as *x=1; x[1] = 2; //is the same as *(x + (sizeof(int) *1)) = 2; //manual pointer math a 2d array is simply a pointer to a pointer. int my2d[5][5]; the first index is pulling a pointer to the actual array (and since and array is simply a pointer) it's a pointer to a pointer. if you wanted to pull out individual arrays you could int my2d[5][5]; int *ptr; //ptr is now an array of my2d[0][0-4] ptr = my2d[0] //ptr[4] is the same as my2d[0][4] so another way to pass a 2d array would be. void myFunct(int **array); called by same int myArray[5][5]; myFucnt(myArray);
