How can I get the number of elements in an array in C?
Ah, honey, in C, you can get the number of elements in an array by dividing the total size of the array by the size of one element. So, if you have an array of integers, you can do something like int size = sizeof(array) / sizeof(array[0]); and voilà, you've got the number of elements. Just be careful with those pesky pointers and make sure you're not trying to count elements in a pointer instead of an actual array.
How do you count the number of elements in an array using PHP?
Using the function "count". <?php $foo = array("John", "Jacob", "Jingleheimer", "Schmidt"); echo count($foo); // <-- outputs the number 4 ?>
How do you access and store the elements of array?
#include<stdio.h> #include<conio.h> int main(void) { int a[10],i;//array declaration clrscr(); printf("\n enter the elements of array"); for(i=0;i<10;i++) scanf("%d",&a[i]); printf("\n the elements you enter into the array"); for(i=0;i<10;i++) printf("%5d",a[i]); getch(); return 0; }
Program to print sorting of an array in clanguage?
/* PROGRAM TO SORT ARRAY ELEMENTS USING BUBBLE SORT*/ #include #include void main() { int i,j,n,t,a[50]; clrscr(); printf("ENTER THE ARRAY SIZE:\n"); scanf("%d",&n); printf("ENTER THE ARRAY ELEMENTS:\n"); for(i=0;i
The maximum number of records you might want to store in an array is defined as MAX When using 0 based indexing what index will reference the last allocated position of an array of size MAX?
If all elements of the array are in use then the last record is referred to as MAX-1. If you are using a count variable to remember how far into the array you are using then this variable will keep track of the last allocated value in the array.
Sum of n numbers using array?
Set sum = 0, then add each of the elements of the array, one by one. Use a for loop to process each element of the array.Set sum = 0, then add each of the elements of the array, one by one. Use a for loop to process each element of the array.Set sum = 0, then add each of the elements of the array, one by one. Use a for loop to process each element of the array.Set sum = 0, then add each of the elements of the array, one by one. Use a for loop to process each element of the array.
What is the algorithm using c to delete duplicate elements from an array?
To detect the duplicate, you will have to write a nested loop that compares each element with all the previous elements.To actually delete the duplicate, once you find it, you have to move over all the elements after the duplicate. If the order of the elements doesn't matter, it is faster to just move the LAST array element, overwriting the duplicate element. Use a variable to keep track how many elements of the array are "usable". For example, if your array had 10 elements, and you delete 1, the array size will still be 10... but (after moving the elements over) only 9 of those elements have useful information.
How do you access 2D array elements by using single variable?
int main() { int array[3][3]; int i; for(i=0; i <9;i++) { printf("the element is %d\n", array[i/3][i%3]); } return 0; }
Can array size be determined using sizeof operator in c?
Yes. The array name is a reference to the array, so you can use sizeof (name) / sizeof (name[0]) to determine the number of elements. Note that sizeof (name) alone gives the length of the array in bytes.
What is peep operation in stack using array in c?
I guess you mean operation top: return the topmost element without deleting it from the stack.int top (const struct stack *from, stacktype *into){if (from->elements==0) return -1; /* EMPTY */*into = from->array[from->elements -1];return 0; /* OK */}compare with pop:int pop (struct stack *from, stacktype *into){if (from->elements==0) return -1; /* EMPTY */*into = from->array[from->elements -1];--from->elements;return 0; /* OK */}
Why multidimensional array element access using indirection operator?
The number of dimensions is immaterial. All arrays are implemented as a one dimensional array. A multidimensional array is simply an array where every element is itself an array. The only thing actually known about any array is that its name is a reference to the start address. Unlike an ordinary (non-array) variable, the elements in the array do not have names, we can only refer to them by their memory offsets from the start of the array. As such, in order to obtain the values stored at those offsets, we must dereference them. While the subscript operator gives us notational convenience, it's easy to forget that there's actually pointer arithmetic and dereferencing going on behind the scenes.
