Given a four digit number N as input write a program to print first and last digit of the number

Quite tiring to write those things separated by commas and a single space, isn't it?

Then let's try coding it instead

Five lines containing a string on each.

A single line containing all the strings separated by a comma and a space.

Have you ever answered a test question that tells you to enumerate a series of things, but the answer must be in a sentence? Quite tiring to write those things separated by commas and a single space, isn't it?

Then let's try coding it instead

Given a list of integers, write a program to print the count of all possible unique combinations of numbers whose sum is equal to k.

Input:

The first line of Input will contain space-separated Integer.

The second line of Input will contain an 8nteger,denoting K.

Sample Input:

2 4 6 1 3

Output:

3

1. In the code editor, you are provided with a main() function that asks the user for two integers and calls the slowDisplay() function.
2. This slowDisplay() function is a recursive function which should perform the functionality explained in the problem description above.
3. This function is only partially implemented as it lacks a base case. Your task is to add the base case needed by this recursive function.

Example:

Starting num = 2

Next num = 3

It should then print 3 4 5

Given code:

#include <iostream>

using namespace std;

void slowDisplay(int, int);

int main(void) {

  int start, nextCount;

  cout << "Enter starting integer: ";

  cin >> start;

  cout << "Enter how many next integers: ";

  cin >> nextCount;

  slowDisplay(start + 1, nextCount);

  return 0;

}

void slowDisplay(int start, int nextCount) {

  // TODO: Add the base case here

  if(start == 0) {

    cout << start << " ";

    slowDisplay(start + 1, nextCount - 1);

  }

}

1. In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString().
2. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function.

To do: Print the string repeatedly, each time it prints the string, exclude the last letter until only 1 letter is left.

Given code:

#include <iostream>

#include <cstring>

using namespace std;

#define STR_MAX_SIZE 100

void preserveString(char*, int);

int main(void) {

  char str[STR_MAX_SIZE];

  cout << "Enter string: ";

  fgets(str, STR_MAX_SIZE, stdin);

  preserveString(str, strlen(str));

  return 0;

}

void preserveString(char *str, int size) {

  if(size > 0) {

    for(int i = 0; i < size - 1; i++) {

      cout << str[i];

    }

    cout << endl;

    // TODO: Add the recursive case of the function here

  }

}

#include <iostream>

ung namespace std;

#include <string> class snident

string name="DefaultName":

string birthyear= "9999":

Your Code Here

int main(){

sident $1;

student $2("Geoffrey Hinton"); student $3("Yann LeCun", "1960");

s1.print_info(); print_info();

$3.print_info():

$2.change year(1947");

s1 change_name("YourName");

s1.change year("YourBirth Year>");

$2.print info(); $1.print_info();

return 0;

Complete the student class so the main function above produces the following output:

Name: DefaultName, Birth Year: 9999

Name: Geoffrey Hinton, Birth Year: 9999.

Name: Yann LeCun, Birth Year: 1960 Name: Geoffrey Hinton, Birth Year: 1947.

Name: YourName, Birth Year: <Your Birth Year>

• Using Php Script write a program that will compute the students average

• The user will input the following:

 Name

 Math

 Science

 English

• If the average is equal and above 75, it will display “Congratulations. You passed the semester” otherwise “You failed the semester.”
