Write a function that accepts a pointer to a C-string as an argument and returns the number of words contained in the string. For instance, if the string argument is 'Four score and seven years ago,' the function should return the number 6. Demonstrate the function in a program that asks the user to input a string and then passes it to the function. The number of words in the string should be displayed on the screen.

To preserve the original format of the answer, I've added it as an attachment

Explanation:

This line defines the function

int countWords(const char ptr){

This line initializes number of words to 0

   int words = 0;

The following iteration is repeated until the last character in the argument is reached

   while(*(ptr) != \0){

This checks if current character is blank

       if(*ptr==  ){

If yes, then it increments number of words by 1

       words++;

 }

This moves the pointer to the next character

       ptr++;

   }

This returns the number of words in the argument

   return words+1;

}

The main begins here

int main() {

This declares user input as a character of 200 length

   char userinput[200];

This prompts user for input

   cout << Enter a string: (200 max): ;

This gets user input

cin.getline(userinput, 200);

This passes the c-string to the function and also prints the number of words

cout << There are  << countWords(userinput)<< words;

the answer is d.

the correct answer is a) her connection with a character

this is correct on edgnuity : )
