Prompt the user to enter a string of their choosing. output the string. (1 pt) ex: enter a sentence or phrase: the only thing we have to fear is fear itself. you entered: the only thing we have to fear is fear itself.(2) complete the getnumofcharacters() function, which returns the number of characters in the user's string. we encourage you to use a for loop in this function. (2 pts)(3) in call the getnumofcharacters() function and then output the returned result. (1 pt)(4) implement the outputwithoutwhitespace() function. outputwithoutwhitespace() outputs the string's characters except for whitespace (spaces, tabs). note: a tab is '\t'. call the outputwithoutwhitespace() function in (2 pts) ex: enter a sentence or phrase: the only thing we have to fear is fear itself. you entered: the only thing we have to fear is fear itself. number of characters: 46 string with no whitespace: .' c++ c++ c++ is what i have so far: #include #include using namespace std; //returns the number of characters in usrstrint getnumofcharacters(int usrstr) {usercount = usrstr. length(); return usercount; }const outputwithoutwhitespaces(string& ; usrstr) {string text; text = text. replace(" ",""); return text; }int main() {string usrstr; cout < < "enter a sentence or phrase: "; getline(cin, usrstr); cout < < "you entered: " < < usrstr < < endl; int count = getnumofcharacters(); cout < < "number of characters: " < < count < < endl; cout < < "string with no whitespace: " < < outputwithoutwhitespace() < < endl; return 0; }

Explanation:

Section 1) Enter String and Output String

#include<iostream> //for input and output  

#include <string>  // for string  

using namespace std;  

int main()  

{  

   string sentense;

   cout<<"Enter a sentence or phrase: ";

 getline(cin,sentense);

 cout<<"You Entered :"<<sentense;

   return 0;  

}

Output

Enter a sentence or phrase: The only thing we have to fear is fear itself

You Entered :The only thing we have to fear is fear itself

Explanation

To get full sentence or phrase, we need to call getline function in string package which will get the overall entered string. cin will not get the whole sentence

Section 2) GetNumOfCharacters

int getNumberOfCharacters(string sentence){

int count =0;

for(int i=0; i<sentence.size(); i++){

 count++;

}

return count;

}

Explanation

As we have taken sentence as string in previous section, we need to count total number of characters in the input string. for that purpose we are iterating over all the characters within string through for loop. declaring count variable and initializing it with 0 and increment on every for loop iteration. at the end returning the count variable.

Section 3) Call the GetNumOfCharacters() in main method.

int main()  

{  

   string sentence;

   cout<<"Enter a sentence or phrase: ";

 getline(cin,sentence);

 cout<< getNumberOfCharacters(sentence);  //Here we call out method and output its value

   return 0;  

}

Explanation

In main method first we get the sentence with getline and then by using cout and calling the getNumberOfCharacters(sentence) function it will show the number of characters in string.

Output

Enter a sentence or phrase: The only thing we have to fear is fear itself

45

Section 4) Implement OutputWithoutWhitespace() function

#include<iostream> //for input and output  

#include <string>  // for string  

using namespace std;  

int getNumberOfCharacters(string sentence){

int count =0;

for(int i=0; i<sentence.size(); i++){

 count++;

}

return count;

}

void OutputWithoutWhitespace(string sentence){

string output="";

 for(int i=0; i<sentence.size(); i++){

 if(sentence[i]!=' ' && sentence[i] != '\t'){  // checking the tab and spaces

 output+=sentence[i];  //then add that into output string

 }

}

cout<< output;

}

int main()  

{  

   string sentence;

   cout<<"Enter a sentence or phrase: ";

 getline(cin,sentence);

 OutputWithoutWhitespace(sentence);

   return 0;  

}  

Code Explanation

In OutputWithoutWhitespace() function we get string as a parameter and iterating all the characters and if current iteration character from sentence string is not equal to tab('\t') and space then add that character into output string. After the loop is finished, output the result.

Output

Enter a sentence or phrase: The only thing we have to fear is fear itself       hello
