Count the positive, negative and zero values from an Array elements using C Programming Language
C program to count Positive , Negative and zero numbers in an Array
Last Updated : 12 Sep, 2022
Given an array arr of integers of size N, the task is to find the count of positive numbers and negative numbers in the array Examples:
Input: arr[] = {2, -1, 5, 6, 0, -3} Output: Positive elements = 3 Negative elements = 2 There are 3 positive, 2 negative, and 1 zero. Input: arr[] = {4, 0, -2, -9, -7, 1} Output: Positive elements = 2 Negative elements = 3 There are 2 positive, 3 negative, and 1 zero.
Approach:
Traverse the elements in the array one by one.
For each element, check if the element is less than 0. If it is, then increment the count of negative elements.
For each element, check if the element is greater than 0. If it is, then increment the count of positive elements.
Print the count of negative and positive elements.
Below is the implementation of the above approach:
see the video
Output:
Array: 2 -1 5 6 0 -3
Count of Positive elements = 3
Count of Negative elements = 2
Time complexity: O(n) where n is size of the given array
Auxiliary space: O(1)
