Question

Write the c++ program that will take form the user his/her personal details: firstname, lastname,

adres and will save them in the character arrays. The program should contain the function that
will return the number of characters stored in the particular strings.

Answer 1

#include <iostream>

#include <cstring>

using namespace std;

const int MAX_LEN = 100; // maximum length of character arrays

// Function to return the number of characters in a string

int getStringLength(char* str) {

return strlen(str);

}

int main(){
char firstName[MAX_LEN];

char lastName[MAX_LEN];

char address[MAX_LEN];

// Get user's personal details

cout << "Enter your first name: ";

cin.getline(firstName, MAX_LEN);

cout << "Enter your last name: ";

cin.getline(lastName, MAX_LEN);

cout << "Enter your address: ";

cin.getline(address, MAX_LEN);

// Print the number of characters in each string

cout << "Number of characters in first name: " << getStringLength(firstName) << endl;

cout << "Number of characters in last name: " << getStringLength(lastName) << endl;

cout << "Number of characters in address: " << getStringLength(address) << endl;

return 0;
