Question

Question 2 Write a program that will read in a line of text up to 100 characters as string, and output the number of words in the line and the number of occurrences of each letter. Define a word to be any string of letters that is delimited at each end by whitespace, a period, a comma, or the beginning or end of the line. You can assume that the input consists entirely of letters, whitespace, commas, an<d periods. When outputting the number of letters that occur in a line, be sure to count upper- and lowercase versions of a letter as the same letter. Output the letters in alphabetical order and list only those letters that do occur in the input line. For example: I say Hi.

Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

// C++ program to print words in a sentence
#include <iostream>
using namespace std;

void CountAll(string str,int& numw,int a[])
{
string word = "";
for (int i=0;i<str.length();i++)
{
char x=str[i];
if (x == ' '||x==','||x=='.')
{
numw++;
word = "";

}
else
{
if(x>='a'&&x<='z')
a[x-'a']++;
if(x>='A'&&x<='Z')
a[x-'A']++;

word = word + x;
}
}
if(word.length()>0)
numw++;
}

// Driver function
int main()
{
cout<<"Enter a text line: ";
string str;
getline(cin,str);
int numw=0;
int a[26]={0};
CountAll(str,numw,a);
cout<<"Number of words are: "<<numw<<endl;
cout<<"Count of all letters are: ";
cout<<endl;
for(int i=0;i<26;i++)
cout<<(char)('a'+i)<<" "<<a[i]<<endl;
return 0;
}

Kindly revert for any queries

Thanks.
