Question

Using C++

And

#include <stdio.h>

#include <stdlib.h>

#include <time.h>

a) Write a main function and declare an array with 100 elements.

b) In the main, initialize each number in the array to be a random number between 100 and 200.

c) Write a function that returns the value of the smallest number in the array. Call this function from the main and print the result.

d) Declare a 2D array with dimensions 2x2 and initilize the array, as follows:

[1, 2;

3, 4]

Answer 1

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

// Write a function that returns the value of the smallest number in the array.
int smallest(int arr[], int size) {
    int min = arr[0];
    for (int i = 0; i < size; ++i) {
        if (arr[i] < min) {
            min = arr[i];
        }
    }
    return min;
}

int main() {
    srand(time(NULL));
    // a) Write a main function and declare an array with 100 elements.
    int arr[100], i;

    // b) In the main, initialize each number in the array to be a random number between 100 and 200.
    for (i = 0; i < 100; ++i) {
        arr[i] = 100 + (rand() % 101);
    }

    // c) Call this function from the main and print the result.
    printf("%d\n", smallest(arr, 100));

    // d) Declare a 2D array with dimensions 2x2 and initialize the array, as follows
    int matrix[2][2] = {{1, 2}, {3, 4}};
    return 0;
