Question

6. As a practical joke, a friend gives you an int array for your birthday. As if that weren’t bad enough, your friend tells you that the array contains almost all 0’s except for a small string of consecutive 1’s contained somewhere in the middle. Overwhelmed by the novelty of this you decide to write a function that will print out the location of the first 1 in the array, the location of the last 1 in the array, and the total number of 1’s in the list of consecutive 1 values. Given below is the function prototype where num is the array of int values and max contains the number of elements in the array. void joke (int num[], int max);

7. Write a function day_of_year(month, day, year) that returns the day of the year (an integer between 1 and 360) specified by the three arguments.

8. Write a function num_digits(n) that returns the number of digits in a positive integer n. Hint: To determine the number of digits in a number n, divide n by 10 repeatedly. When n reaches 0, the number of divisions indicates how many digits n originally had.

Answer 1

6)

int []num = { 0, 0, 0, 1, 0, 0, 1, 1, 1, 0, 0, 0 };
int firstIndex = Array.IndexOf(num, 1);
int lastIndex = Array.LastIndexOf(num, 1);
int count=0;

for(int i=0;i<num.Length;i++)
{
if(num[i]==1)
{
count=count++;
}
}

Console.WriteLine("First index is " + firstIndex);
Console.WriteLine("Last index is " + lastIndex);
Console.WriteLine("Total count is " + count);
Console.ReadLine();
