Answer:


Program Plan Intro

Program plan:

  • Declare the variable number of integer type.
  • The cout statement is used to prompt a message to user and display output.
  • The cin statement is used to take an input from user.

Program description:

The following program will take an input from user and display its integer output.

Program Explanation

Program

//header file included
#include<iostream>
//namespace included
usingnamespace std;
//main function
intmain()
{
//Declare variable number of int type
int number;
//cout statement
cout<<"Enter a number:"<<endl;
//cin statement
cin>>number;
//display output
cout<<number;
//exiting from program
return 0;
}

Explanation:

In the above program, inputted number from a user using cin statement. Displayed the inputted number immediately using cout statement.

Observed output:-

if inputted number is of integer type then displayed output is also the same number.

if inputted number is of double-precision type then displayed output is also only the integer part of number.

if inputted number is of character type then displayed output is 0.

QUESTION 6 (a) The bar shown in Figure Q2(a) is subjected to tensile load of 150 Kn. If the stress in the middle portions is limited to 160 N/mm², determine the diameter of the middle portion. Find also the length of the middle portion if the total elongation of the bar is to be 0.25 mm. E E = 2.0 + 105N/mm².
