Length of the array data structure by R4R Team

Array:

Array is the collection of different values having same data type.
-We have a integer Array that having all integer values.
-Character array is known as String.

Size of Array:
Total elements*sizeof(one element)

Length of Array:
Formula:
length=sizeof(array)/sizeof(a[i])
-Here a[i] shows the one element of the array.

Example-
Array is {1,2,3,4,5}
Then sizeof(Array) is 20
and sizeof(int) is 4
then length is 20/4=5

program-

#include < stdio.h>
int main()
{
int a[6],b[100],c[500];
printf("Size of first array is %d",sizeof(a)/sizeof(a[0]));
printf("Size of second array is %d",sizeof(b)/sizeof(b[0]));
printf("Size of third array is %d",sizeof(c)/sizeof(c[0]));
}


output-

Size of first array is 6
Size of second array is 100
Size of third array is 500
