Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in
Zina [86]

Answer:

Here is the C++ program:

#include <iostream> // to include input output functions

using namespace std; // to identify objects like cin cout

int counter(string userString, char character) { //function counter

   int count = 0;   // counts the no of times a character appears in the string

   for (int i=0;i<userString.length();i++)  

// loop to move through the string to find the occurrence of the character

       if (userString[i] == character) //if characters is found in the string

           count++;   //counts the occurrence of the character in the string

   return count; }   //returns the no of times character occurs in the string

int main() { //start of the main() function body

   string s; // stores the string entered by the user

   cout<<"Enter a string: "; //prompts user to enter the string

   cin>>s; //reads the string from user

   char ch; //stores the character entered by the user

   cout<<"Enter a character: "; //prompts user to enter a character

   cin>>ch; //reads the character from user

   cout << counter(s, ch) << endl; }  

//calls counter function to find the number of times a character occurs in the //string

Explanation:

The counter function works as following:

It has a count variable which stores the number of occurrences of a character in the userString.

It uses a for loop which loops through the entire string.

It has i position variable which starts with the first character of the string and checks if the first character of userString matches with the required character.

If it matches the character then count variable counts the first occurrence of the character and in the userString and is incremented to 1.

If the character does not match with the first character of the userString then the loops keeps traversing through the userString until the end of the userString is reached which is specified by the length() function which returns the length of the string.

After the loop ends the return count statement is used to return the number of occurrences of the character in the userString.

The main() function prompts the user to enter a string and a character. It then calls counter() function passing string s and character ch arguments to it in order to get the number of times ch appears in s.

The output is attached in a screenshot.

Liono4ka [1.6K]

Answer:

public class Main

{

public static void main(String[] args) {

    int carYear = 1995;

   

    if(carYear < 1967)

        System.out.println("Probably has few safety features.");

    if(carYear > 1971)

        System.out.println("Probably has head rests.");

    if(carYear > 1992)

        System.out.println("Probably has anti-lock brakes.");

    if(carYear > 2002)

        System.out.println("Probably has tire-pressure monitor.");

   

}

}

Explanation:

The code is in Java.

Initialize the carYear

Use if statements to handle year before 1967, after 1971, after 1992 and after 2002.

Print the required message for each if statement
