In this tutorial you will learn about the C example to Count Even and Odd Numbers in an Array and its application with practical example.
C example to Count Even and Odd Numbers in an Array
In this tutorial, we will learn to create a C program that will Count Even and Odd Numbers in an Array using C programming.
Prerequisites
Before starting with this tutorial, we assume that you are the best aware of the following C programming topics:
- Operators in C Programming.
- Basic Input and Output function in C Programming.
- Basic C programming.
- For loop in C programming.
- Arithmetic operations in C Programming.
What is Even and Odd number?
A number is said to be an even number when that number is divided by two into two equal whole numbers. A number is said to be an odd number when that number is divided by two into two, not equal whole numbers.
What is An array?
The array is a collection of similar data types. An array can store multiple values with different indexes in memory by using a single variable. The array can be both single as well as multidimensional.
Program to Count Even and Odd Numbers in an Array.
In this program, we will first take the input array size and the elements from the user. Then we will separate the even and odd numbers from that array. After that, we will count the even as we as odd valued elements. At last, we will print that number of even and odd elements.
With the help of this program, we can Count Even and Odd Numbers in an Array.

/* C Program to Count Even and Odd Numbers in an Array */ #include<stdio.h> int main() { //declaring the required variables for the program int Size, i, a[10]; int Even_Count = 0, Odd_Count = 0; //i = it will hld the integer value for the prorgam. //a[10] = it will hld the integer value for the prorgam. //Size = it will hld the integer value for the prorgam. //Even_Count = it will hld the integer value for the prorgam. //Odd_Count = it will hld the integer value for the prorgam. //Taking the input size of the array. printf("\n Please Enter the Size of an Array : "); scanf("%d", &Size); //Taking the elements of the array. printf("\nPlease Enter the Array Elements\n"); for(i = 0; i < Size; i++) { scanf("%d", &a[i]); } //Seperating the even and odd numbers from the array. for(i = 0; i < Size; i ++) { if(a[i] % 2 == 0) { Even_Count++; } else { Odd_Count++; } } //Printing the even and odd numbers from the user. printf("\n Total Number of Even Numbers in this Array = %d ", Even_Count); printf("\n Total Number of Odd Numbers in this Array = %d ", Odd_Count); return 0; } |
Output:-
In the above program, we have first initialized the required variable.
- Even_Count = it will hold the integer value.
- Odd_Count = it will hold the integer value.
- i = it will hold the integer value.
- Size = it will hold the integer value of the input.
Input number of elements from the user.
Program Logic Code.
Printing output of the program.
