Question

Write a program that asks the user to give you a number, then use that number to read a number of strings equal to that number, and finally compute the total length

Answer 1

/**
The c++ program that prompts user to enter number of string to enter.
Then prompt for strings. Then print total length of the strings entered
by user.
*/

//include header files
#include <iostream>
#include <string>
using namespace std;

int main()
{  

   //declare variables
   int size;
    int length=0;
   //create an pointer of type string
   string *words;

   cout<<"Give me some words."<<endl;
   cout<<"I will count the total number of characters they have. "<<endl;
   cout<<"How many words : ";
   //prompt for size
   cin>>size;

   //create array of pointers to read strints
   words=new string[size];
    for(int i = 0; i < size; i++)
   {

       cout<<"Enter a string : ";
       //prompt for words
        cin>>words[i];

       //The method length() retunrs length of the string
       //add lenght of the words to lenght
       length+=words[i].length();
    }

   //print total lenght of the strings
   cout<<"Your strings have total length "<<length<<endl;

   system("pause");
    return 0;

}

Give me some words I will count the total number of characters they have How many words2 Enter a string hello Enter a string hello Your strings have total length 10
