Question

(For the following assignment, please answer in the most SIMPLEST FORM possible. Nothing too intricate as I am only a beginner.

Label each one my its exercise, so I know which one is which.

THANK YOU)

Exercise 5
Write a function that takes an array a of integers and its size n and returns the minimum value of the array. Propose a prototype for the function. Write its code and a tester to demonstrate its use.

Continuation of Exercise 5
Redo exercise 5 using vectors. The problem statement becomes: write a function that takes a vector of integers and returns the minimum value in the vector.

C++ LANGUAGE

Explanation / Answer

Exercise 5.

#include<iostream>

using namespace std;

int fxn( int arr[], int n )

{

    int i;

    int min =INT_MAX;

    for( i = 0 ; i < n ; i++ )

        // if the current element is smaller than min

        if( arr[i] < min )

            min = arr[i];

    return min;

}

int main()

{

    int arr[] = { 5, 3, 6, 1, -2, 5 };

    cout<<"Min element : "<<fxn( arr, 6 );

    return 0;

}

With Vectors

#include<iostream>

#include<vector>

using namespace std;

int fxn( vector<int> arr )

{

    int i;

    int min =INT_MAX;

    for( i = 0 ; i < arr.size() ; i++ )

        // if the current element is smaller than min

        if( arr[i] < min )

            min = arr[i];

    return min;

}

int main()

{

    vector<int> arr;

    arr.push_back(6);

  arr.push_back(4);

    arr.push_back(7);

    arr.push_back(1);

    arr.push_back(-2);

    arr.push_back(4);

    cout<<"Min element : "<<fxn( arr );

    return 0;

}
