Question

Question 5: Recommend / Explain a C++ program which uses an array of 20 integers whose input is taken by user, the array is passed to a functions named i.e. smallest(int A[20) and largest(int B[20]) to determine minimum and maximum values respectively.

Also create a function named modify(int *p) which modifies the value at the index given by user.

Answer 1

//C++ code:

#include <bits/stdc++.h>
using namespace std;

int largest(int B[20]) {
    int i;
    
    // Initializing maximum element
    int max = B[0];

    // Traverse array elements
    // from second and compare
    // every element with current max
    for (i = 1; i < 20; i++)
        if (B[i] > max)
            max = B[i];

    return max;
}
int smallest(int A[20]) {
    int i;
    
    // Initializing minimum element
    int min = A[0];

    // Traverse array elements
    // from second and compare
    // every element with current min
    for (i = 1; i < 20; i++)
        if (A[i] < min)
            min = A[i];

    return min;
}
void modify(int *p){
    int index,val,i;
    cout<<"Enter the index of element to be modified: ";
    cin>>index;
  
    cout<<"Enter the value to modify it with: ";
    cin>>val;
  
    p[index]=val;
    cout << "The array after modification: ";

    //printing array elements
    for(i=0;i<20;i++){
        cout << p[i]<<" ";
    }
    return;
  
}

// Driver Code
int main()
{
    int a[20],i;
    cout<<"Enter the elements of array: ";
    for(i=0;i<20;i++){
        cin>>a[i];
    }
  
  

    cout << "Largest value in the array is "
         << largest(a)<<endl;
    cout << "Smallest value in the array is "
         << smallest(a)<<endl;
  
     modify(a);

return 0;
}
