8. large=a[i];

How do you find min and max in C?

Logic to find maximum and minimum element in an array in C:

1. Create two intermediate variables max and min to store the maximum and minimum element of the array.
2. Assume the first array element as maximum and minimum both, say max = arr[0] and min = arr[0].
3. Traverse the given array arr[].

How do you find the largest and smallest number in an unsorted integer array C++?

The program output is shown below.

1. #include
2. using namespace std;
3. int main ()
4. {
5. int arr[10], n, i, max, min;
6. cout << “Enter the size of the array : “;
7. cin >> n;
8. cout << “Enter the elements of the array : “;

How do you find the smallest element in an array?

For an array of ascending order the first element is the smallest element, you can get it by arr[0] (0 based indexing). If the array is sorted in descending order then the last element is the smallest element,you can get it by arr[sizeOfArray-1].

How do you find the length of an array in C?

Calculate the size of the array using sizeof operator e.g. sizeof(arr). Calculate the size of an int value using sizeof(int). To get the length of the array( number of elements), divide total size of array by size of 1 int.

Which of the following methods can be used to find the largest and smallest element in an array?

Which of the following methods can be used to find the largest and smallest element in an array? Explanation: Both recursion and iteration can be used to find the largest and smallest element in an array.

How do you find the maximum and minimum?

Finding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f.

How do you find the largest value in an array?

To find the largest element from the array, a simple way is to arrange the elements in ascending order. After sorting, the first element will represent the smallest element, the next element will be the second smallest, and going on, the last element will be the largest element of the array. Sort the array.

How do you find the minimum of 3 numbers in C?

Program Explanation Get three inputs num1, num2 and num3 from user using scanf statements. Check whether num1 is smaller than num2 and num3 using if statement, if it is true print num1 is smallest using printf statement. Else, num2 or num3 is smallest. So check whether num2 is smaller than num3 using elseif statement.

How do you find the second smallest element in an array?

Method 2 to find the second smallest element in an array

1. Declare an array and input the array elements.
2. Find the smallest element (first_smallest) in the array in the first traversal.
3. Find the smallest element (second_smallest) by skipping the first_smallest element.
4. Display second_smallest.

How do you find the length of a string in C?

Use the strlen() function provided by the C standard library string. h header file. char name[7] = “Flavio”; strlen(name); This function will return the length of a string as an integer value.
