Question

C++

A Program for Examining String

(1) Ask the customer to type any string they like and then print it to the console.

Example:

Type a sentence:

The CIS161 Computer Science II course is so much fun!

You typed: The CIS161 Computer Science II course is so much fun!

(2) Write the remaining code for the CountOfLetters() function, which returns the number of characters in the string that was entered. To get full credit for this question, this should be implemented with the use of a for loop.

(3) The CountOfLetters() function should be called from main() and the value returned must be printed.

(4) Implement the PrintEverythingExceptWhitespaces() function.

PrintEverythingExceptWhitespaces() prints the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'. Call the PrintEverythingExceptWhitespaces() function in main().

Ex:

The CIS161 Computer Science II course is so much fun!

You typed: The CIS161 Computer Science II course is so much fun!

Number of characters: 53

String with no whitespace:

TheCIS161ComputerScienceIIcourseissomuchfun!

This is what we are given to work with:

#include <iostream>
#include <string>
using namespace std;

//Returns the number of characters in usrStr
int CountOfLetters(const string usrStr) {

/* Type your code here. */

}

int main() {

/* Type your code here. */

return 0;
}

Answer 1

Please find the code below.

#include <iostream>
#include <string>

using namespace std;

int CountOfLetters(const string usrStr) {

int count = 0;
for (int i=0;i<usrStr.length();i++) {
count++;
}

return(count);
}

void PrintEverythingExceptWhitespaces(string str){
int i=0,j=0,k=0;
string str1;
while (str[i])
{
   if(str[i]!=' ')
   str[j++]=str[i];
   i++;
}
   str[j]='\0';
   for(k=0;k<str.length()-8;k++)
cout << str[k];
}

int main()
{   
string str;
cout<<"Type a sentence:\n";
getline(cin, str);
cout << "You typed: " << str;
cout<<"\n";
cout<<"Number of characters: "<<CountOfLetters(str);
cout<<"\n";
cout<<"String with no whitespace :";
PrintEverythingExceptWhitespaces(str);
return 0;
}

Output:
