Answer:
1st question:
Use the variables k, d, and s so that they can read three different values from standard input an integer, a float, and a string respectively. On one line, print these variables in reverse order with exactly one space in between each. On a second line, print them in the original order with one space in between them.
Solution:
In Python:
k = input() #prompts user to input value of k i.e. integer value
d = input() #prompts user to input value of d i.e. float value
s = input() #prompts user to input value of s i.e. a string
print (s, d, k) #displays these variable values in reverse order
print (k, d, s)#displays these variable values in original order
In C++:
#include <iostream> // to use input output functions
using namespace std; //to identify objects like cin cout
int main() { //start of main function
int k; //declare int type variable to store an integer value
float d; // declare float type variable to store a float value
string s; // declare string type variable to store an integer value
cin >> k >> d >> s; //reads the value of k, d and s
cout << s << " " << d << " " << k << endl; //displays these variables values in reverse order
cout << k << " " << d << " " << s << endl; } // displays these variable values in original order
Explanation:
2nd question:
You would like the user of a program to enter a customer’s last name. Write a statement that asks user "Last Name:" and assigns input to a string variable called last_name.
Solution:
In Python:
last_name = input("Last Name:")
# input function is used to accept input from user and assign the input value to last_name variable
In C++:
string last_name; //declares a string type variable named last_name
cout<<"Last Name: "; // prompts user to enter last name by displaying this message Last Name:
cin>>last_name; // reads and assigns the input value to string variable last_name
The programs alongwith their outputs are attached.
Answer:
Following are the code to this question:
#include<iostream>//declaring header file
using namespace std;
int main()//main method
{
int n= 6,j=0;//declaring integer variable
int X[n];//defining an array
for(j=0;j<=n;j++)//defining a loop for input value
cin>>X[j];//input value from the user
if(j==0) //defining if block that checks value at beginning
{
if(X[j]>=X[j+1])//defining if block to check to compare first and second value
{
cout<<"A peak is at array index "<<j<<" and the value is "<<X[j];//use print method to largest value with index number
}
}
else//defining else block
{
for(j=0;j<=n;j++)//defining for loop for compare other value
{
if(j==n-1) //use if block that checks next index
{
if(X[j]>=X[j-1])//use if block to compare value
cout<<"A peak is at array index "<<j<<" and the value is "<<X[j];//use print method to largest value with index number
}
else
{
if(X[j]>=X[j-1] && X[j]>=X[j+1])//comapre value
cout<<"A peak is at array index "<<j<<" and the value is "<<X[j];//use print method to largest value with index number
}
}
}
return 0;
}
Output:

Explanation:
In the given code, inside the main method two integer variable "n and j", is declared, in the next step, an array "x"is defined which input the value from the user end.
- In the next step, multiple if block is used, in the first if block it comapre the first and second value if it grater then it will print the value with its index number.
- In the next if block, it comapre is next value and if it grater then it will print the value with its index number.
