C++ Min



c++ program to find maximum and minimum of n numbers

We will follow simple steps to write a program to find the maximum and minimum of n numbers.

We would like to show you a description here but the site won’t allow us. C Find max and min Element and Respective Index in a Vector Example. To find the largest or smallest element stored in a vector, you can use the methods std::maxelement and std::minelement, respectively. These methods are defined in header. If several elements are equivalent to the greatest (smallest) element, the methods return. In this tutorial, we will learn about the Concept of Min Heap and implementing it using a Priority Queue, in the C programming language. Min Heap Data Structure: Heap data structure is always a Complete Binary Tree, which means all levels of the tree are fully filled.

Steps:
1. Flowchart
2. Algorithm
3. Code

Step 1 and step 2 are baby steps, even you can skip step 1 and what I mean by skipping is just draw a flowchart in your mind. Step 2 is to write your algorithm and then code.

Algorithm
Your first element should be maximum or minimum.
Compare all elements with a minimum or maximum.
Then we tell our system to take a look at whether the element is greater than max or smaller than min, then we change the value of max/min.
Then we give the output.

There are many ways to write code for this given problem and they are given below:

Basic

C++ min max

720p 38 min Fakings - 956.8k Views - 360p. Perversioni Confidenziali 1 h 38 min. 360p 1 h 38 min Miraparaqueteenamores - 3.2M Views - 720p. Returns an iterator pointing to the element with the smallest value in the range first,last). The comparisons are performed using either operator.

The logic behind this code is the same as explained in the algorithm.

Functions

I have used two functions, one for finding the maximum number and the one for the minimum. Then we have to pass the array to the function parameters. The remaining logic is same as previous one.

Pointers

If we use pointers for this function we have to use a little different algorithm. we declared two pointers max and min. max and min are pointing the first element of the array. Now we use “*” operator to access the value.
Now, *max and *min, work similarly to a normal variable containing max/min value of an array.

Returns the smaller of the given values.

3-4) Returns the smallest of the values in initializer list ilist.

The (1,3) versions use operator< to compare the values, the (2,4) versions use the given comparison function comp.

[edit]Parameters

a, b - the values to compare
ilist - initializer list with the values to compare
cmp - comparison function object (i.e. an object that satisfies the requirements of Compare) which returns ​true if a is less than b.

The signature of the comparison function should be equivalent to the following:

bool cmp(const Type1 &a, const Type2 &b);

While the signature does not need to have const&, the function must not modify the objects passed to it and must be able to accept all values of type (possibly const) Type1 and Type2 regardless of value category (thus, Type1 & is not allowed, nor is Type1 unless for Type1 a move is equivalent to a copy(since C++11)).
The types Type1 and Type2 must be such that an object of type T can be implicitly converted to both of them.​

Type requirements
-T must meet the requirements of LessThanComparable in order to use overloads (1,3).
-T must meet the requirements of CopyConstructible in order to use overloads (3,4).

[edit]Return value

1-2) The smaller of a and b. If the values are equivalent, returns a.
3-4) The smallest value in ilist. If several values are equivalent to the smallest, returns the leftmost such value.

[edit]Complexity

3-4) Exactly ilist.size() - 1 comparisons

[edit]Notes

Capturing the result of std::min by reference produces a dangling reference if one of the parameters is a temporary and that parameter is returned:
