Write a program to find the frequency of presence of an element in an array
#include<iostram.h>
#include<iomanip.h>
#include<conio.>
class frequency{
private:
int n, m[100], ele, freq;
public:
void getdata();
void findfreq();
void display();
};
void frequency::getdata(){
cout<<"Enter the size of the array: ";
cin>>n;
cout<<"Enter "<<n<<" elemens into the array: ";
for(int i=0; i<n; i++)
cin>>m[i];
cout<<"Enter the search element: ";
cin>>ele;
}
void frequency::findfreq(){
freq = 0;
for (int i=0; i<n; i++)
if(m[i] == ele)
freq++;
}
void frequency::display(){
if(freq > 0)
count<<"Frequency of "<<ele<<" is "<<freq;
else
cout<<ele<<" does not exist";
}
void main(){
frequency F;
clrscr();
F.getdata();
F.findfreq();
F.display();
getch();
}

OUTPUT: ------------------- Enter the size of the array: 5 Enter 5 elements into the array: 10 50 40 30 40 Enter the search element: 40 Frequency of 40 is 2 -------------------- ------------------- Enter the size of the array: 5 Enter 5 elements into the array: 10 50 40 30 40 Enter the search element: 35 25 does not exist --------------------
