minimum value in array using c++

Code to Find the Minimum Value in an Array Using C++

#include <iostream>

int findMinValue(int arr[], int size) {
    int minValue = arr[0];
    for (int i = 1; i < size; i++) {
        if (arr[i] < minValue) {
            minValue = arr[i];
        }
    }
    return minValue;
}

int main() {
    int array[] = {5, 3, 8, 2, 1};
    int size = sizeof(array) / sizeof(array[0]);
    int minVal = findMinValue(array, size);
    std::cout << "The minimum value in the array is: " << minVal << std::endl;
    return 0;
}

Explanation:

1. Include Necessary Library: The code includes the iostream library to enable input and output stream operations.

2. Define findMinValue Function: A function named findMinValue is defined, which takes an integer array and its size as parameters. It iterates through the array to find the minimum value and returns it.

3. Initialize minValue: The variable minValue is initialized with the first element of the array.

4. Iterate Through Array: A for loop is used to iterate through the array starting from the second element.

5. Check for Minimum Value: Inside the loop, each element is compared with the current minimum value, and if it is smaller, it becomes the new minimum value.

6. Return Minimum Value: After the loop, the minimum value is returned by the function.

7. Main Function: In the main function, an array of integers is defined, and its size is calculated using the sizeof operator.

8. Call findMinValue Function: The findMinValue function is called with the array and its size as arguments, and the result is stored in minVal.

9. Output Result: The minimum value is then printed to the console using cout.

10. Return 0: The main function returns 0 to indicate successful execution.
