C Exercises: Check if the value of each element is equal or greater than the value of previous element of a given array of integers

C-programming basic algorithm: Exercise-74 with Solution

Write a C program to check if the value of each element is equal or greater than the value of the previous element of a given array of integers.

C Code:

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

// Function prototype for 'test'
int test(int nums[], int arr_size);

int main(void){
    int arr_size;
    int array1[] = {5, 5, 1, 5, 5};
    arr_size = sizeof(array1)/sizeof(array1[0]);
    printf("%d", test(array1, arr_size));

    int array2[] = {1, 2, 3, 4};
    arr_size = sizeof(array2)/sizeof(array2[0]);
    printf("\n%d", test(array2, arr_size));

    int array3[] = {3, 3, 5, 5, 5, 5};
    arr_size = sizeof(array3)/sizeof(array3[0]);
    printf("\n%d", test(array3, arr_size));
}       

// Definition of the 'test' function
int test(int nums[], int arr_size)
{
    // Loop to iterate through the array
    for (int i = 0; i < arr_size - 1; i++)
    {
        // Check if the next element is less than the current element
        if (nums[i + 1] < nums[i])
            return 0; // If true, the array is not in non-decreasing order
    }

    return 1; // If the loop completes without returning 0, the array is in non-decreasing order
}

Sample Output:

0
1
1

C Programming Code Editor:

Previous: Write a C program to create new array from a given array of integers shifting all even numbers before all odd numbers.
Next: Write a C program to check a given array (length will be atleast 2) of integers and return true if there are two values 15, 15 next to each other.
