Chapter 8, Problem 1P

Create a C-string variable that contains a name, age, and title. Each field is separated by a space. For example, the string might contain “Bob 45 Programmer” or any other name/age/title in the same format. Assume the name, age, and title have no spaces themselves. Write a program using only functions from cstring (not the class string) that can extract the name, age, and title into separate variables. Test your program with a variety of names, ages, and titles.

Program Plan Intro

Program plan:

  • Include the necessary header files.
  • Declare the namespace.
  • Define the “main()” function.
    • Declare the necessary variables.
    • Initialize the character array.
    •  Use the functions “strtok()” to split the string into tokens.
    • Use the function “strcpy()” to copy the source string into the destination string.
    • Print the result.
Program Description Answer

Program to display name, age and title into separate variables using the function “cstring”.

Explanation of Solution

Program:

//Include the header file iostream

#include<iostream>

//Include the header file cstring

#include<cstring>

//Declare the namespace

using namespace std;

//Define the main() function

int main()

{

  //Declare the necessary variables

  char name[20];

  char age[4];

  char title[50];

  //Initialize the char array

  char res[] = "Bob 45 Programmer";

 /*Call the function strtok() to split str into tokens and assign the result in *pch*/

  char *pch = strtok(res," ");

/*Call the function strcpy to copy the value in pch into     name*/

  strcpy(name,pch);

/*Call the function strtok() to split str into tokens and assign the result in *pch*/

  pch = strtok(NULL," ");

/*Call the function strcpy to copy the value in pch into age*/

  strcpy(age,pch);

/*Call the function strtok() to split str into tokens and assign the result in *pch*/

  pch = strtok(NULL," ");

/*Call the function strcpy to copy the value in pch into title*/

  strcpy(title,pch);

  //print the name

  cout<<"Name: "<<name<<" ";

  //print the age

  cout<<"Age: "<<age<<" ";

  //Print the title

  cout<<"Title: "<<title;

  //Return zero

  return 0;

}

Sample Output

Output:

Name: Bob Age: 45 Title: Programmer

In C programming language, the name of a variable is a string that can contain uppercase letters, lowercase letters, digits, or underscores. Further, the first character in the string must be a letter, either uppercase or lowercase, or an underscore. If the name of a variable is determined by its first eight characters, how many different variables can be named in C? (Note that the name of a variable may contain fewer than eight characters.)
How do I create a wordle like game using C++? Instructions are to create a “target word” by assigning a five-letter word to a string variable. Remember the user’s guess must be: exactly 5 letters long and contain only lowercase letters from a to z. have 6 guesses to get the word Don’t worry about whether it is a valid 5-letter word at this point. Just compare it to the “target word” and report whether it is a match.
Java Program - Functions With Parameters and No Return Values Create a function named palindrome that asks the user a string input if called. If the string is a palindrome, print “{input} is a palindrome!”, otherwise print “{input} is not a palindrome!”.   In the main function, call the palindrome function. Input 1. One line containing a single string Output Enter a string: racecar racecar is a palindrome!
