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 previous element of a given array of integers.

C Code:

#include <stdio.h>
#include <stdlib.h>
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));
    }       
  int test(int nums[], int arr_size)
         {
           for (int i = 0; i < arr_size - 1; i++)
            {
                if (nums[i + 1] < nums[i]) return 0;
            }
            return 1;
        }

Sample Output:

0
1
1

C Programming: Tips of the Day

Why doesn't a+++++b work?

printf("%d",a+++++b); is interpreted as (a++)++ + b according to the Maximal Munch Rule!.

++ (postfix) doesn't evaluate to an lvalue but it requires its operand to be an lvalue.

! 6.4/4 says the next preprocessing token is the longest sequence of characters that could constitute a preprocessing token"
