Write a c++ program to enter a text and count how many times one letter appear in the text?

#include <iostream>

#include<map>//to inlude hashmap..

#include<string>

using namespace std;

int main() {

   string sa;//declaring a string s.

   map<char,int>m;// A hashmap of char type key and integer type value.

   cout<<"Enter the text"<<endl;

   cin>>sa;//taking input of the string..

   for(int i=0;i<sa.length();i++)

   {

       m[sa[i]]++;//increasing the count of character in the hashmap..

   }

   for(auto i:m)//iterating oveer the hashmap m

   {

       cout<<i.first<<" "<<i.second<<endl;//displaying the character and the count..

   }

return 0;

}

Explanation:

I have taken a hashmap m and a string s .I am taking input of text in the string s.The hashmap is of type key =Char and value = int to store the count.After that iterating over the string and updating the count in the hashmap of each character and then printing the count of each character..

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
