Write a C Program to Find the Array Length or size of it. In this programming language, we can use the sizeof operator to find the array’s size or length.
#include <stdio.h>
int main()
{
int arr[] = {10, 20, 30, 40, 50, 60, 70};
int num;
num = sizeof(arr);
printf("The Total Number of Array Items = %d", num);
return 0;
}

The standard way to find the size or length of an array in this Programming is
#include <stdio.h>
int main()
{
int arr[] = {15, 25, 35, 45, 55};
int num;
num = sizeof(arr)/ sizeof(arr[0]);
printf("The Size of a Given = %d", num);
return 0;
}
The Size of a Given = 5
