Frequency count of the Element in an array
Download as PPTX, PDF0 likes172 views
The document outlines a C++ program designed to count the frequency of a specific element in an array. It includes steps for array declaration, inputting values, and using a for loop to determine how many times the specified element appears. A sample code snippet is presented to demonstrate the implementation of the logic.
![Logic
• Given array for example:
• arr[]={1,2,3,2,3,2,2}
• Element to be find is 2 (No.of times repeated)
• How to find the repeated element present in an
array
• Soln:Using for loop:
• for (i=0;i<n;i++)
• if(a[i]==ele)(main logic)
• counter++;](https://image.slidesharecdn.com/frequencycount-200912121451/85/Frequency-count-of-the-Element-in-an-array-3-320.jpg)

Frequency count of the Element in an array
- 1. Find the frequency of presence of an element in an array???
- 2. Agenda 1. Program in c++ 2. Array declaration and definition 3. Enter the element to be counted 4. Counter or freq variable declaration 5. Print the particular element along with a number how many times that number gets repeated in the given array
- 3. Logic • Given array for example: • arr[]={1,2,3,2,3,2,2} • Element to be find is 2 (No.of times repeated) • How to find the repeated element present in an array • Soln:Using for loop: • for (i=0;i<n;i++) • if(a[i]==ele)(main logic) • counter++;
- 4. Let’s See Practically by writing the program
- 5. • #include<iostream.h> • #include<conio.h> • void main() • { • int a[100],ele,n,i,freq; • clrscr(); • cout<<"Enter the size of array"<<endl; • cin>>n; • cout<<"Enter the elements of array"<<endl; • for(i=0;i<n;i++) • { • cin>>a[i]; • } • cout<<"Enter the element to be counted"<<endl; • cin>>ele; • freq=0; • for(i=0;i<n;i++) • { • if(a[i]==ele) • { • freq=freq+1; • } • } • cout<<"Frequency of "<<ele<<" is "<<freq; • getch(); • }
