In this tutorial you will learn about the C Program to Count Total Number of Duplicate Elements in an Array and its application with practical example.
C Program to Count Total Number of Duplicate Elements in an Array
In this tutorial, we will learn to create a C program that will Count the Total Number of Duplicate Elements 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 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.
Count Total Number of Duplicate Elements in an Array.
In this program, First, we will first take the size of the array from the user. Then we will take the elements of the array from the user. After that, we will Count the Total Number of Duplicate Elements in an Array. Then we will print the result array to the user.
With the help of this program, we can be Count the Total Number of Duplicate Elements in an Array.

/* C Program to Count the Total Number of Duplicate Elements in an Array */ #include <stdio.h> int main() { //Declaring the required variables for the program. int arr[10], i, j, Size, Count = 0; //i = it will hold the integer values for the program. //j = it will hold the integer values for the program. //Size = it will hold the integer values for the program. //Count = it will hold the integer values for the program. //arr[10] = it will hold the integer values of the array. //Taking the input size of the array. printf("\n Please Enter Number of elements in an array : "); scanf("%d", &Size); //Taking the input array elements of the. printf("\n Please Enter %d elements of an Array : ", Size); for (i = 0; i < Size; i++) { scanf("%d", &arr[i]); } //Finding the dublicate elements in the array. for (i = 0; i < Size; i++) { for(j = i + 1; j < Size; j++) { if(arr[i] == arr[j]) { Count++; break; } } } //Printing the Duplicate Elements in that Array. printf("\n Total Number of Duplicate Elements in this Array = %d ", Count); return 0; } |
Output:-
In the above program, we have first initialized the required variable.
- j = it will hold the integer value.
- i = it will hold the integer value.
- arr[10] = it will hold the integer value.
- count = it will hold the integer value.
Taking the size of the array and the elements.
Program Code to find the duplicate elements.
Printing output of the program.
