Counting frequency of the character by using map function / implementation of map /stl c++

 Here we are going to implement a map function of STL . and by using this map function we will count the frequency of the elements. 

Code:-

#include<bits/stdc++.h>

using namespace std;

int main()

{

map<int ,int > m;

int t;

cout<<"Enter number of elements"<<endl;

cin>>t;

cout<<"Enter the elements"<<endl;

while(t--)

{

int a;

cin>>a;

m[a]+=1;

}

cout<<"The Frequency of the elements : "<<endl;

for(auto &p:m)

cout<<p.first<<" "<<p.second<<endl;

return 0;

}

Output:-

Enter number of elements

5

Enter the elements

1

2

3

1

2

The Frequency of the elements :

1 2

2 2

3 1
