Q.Write a C++ program to find minimum element in an array.

#include <iostream>     
using namespace std;
  
int main()
{  
    int a[100], size, i, min;
    cout << "Enter the number of elements in array: ";
    cin >> size;
    cout << "Enter the integers: ";
    for (i = 0; i < size; i++)
    {
        cin >> a[i];
    }
    min = a[0];
    for (i = 1; i < size; i++)
    {
        if (a[i] < min)
        {
            min  = a[i];
        }
    }
    cout << "Minimum element in an array is " << min;
    return 0;

Q. Write an algorithm to find minimum element in an array.

1. Start
2. Declare an array `a` with a maximum size (e.g., 100).
3. Declare integer variables `size`, `i`, and `min`.
4. Prompt the user to enter the number of elements and read the input into `size`.
5. Prompt the user to enter the integers.
6. For `i` from 0 to `size - 1`:
    - Read the element and store it in `a[i]`.
7. Initialize `min` with the value of the first element of the array `a[0]`.
8. For `i` from 1 to `size - 1`:
    - Compare `a[i]` with `min`.
    - If `a[i] < min`, update `min = a[i]`.
9. After completing the loop, `min` will hold the minimum element in the array.
10. Print the minimum element.
11. End
