Question

Write a Visual Logic program that prompts the user for a whole number, N, that is less than or equal 50

Answer 1

Answer:

//program in C++(Visual studio).

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variable

int num;

cout<<"Enter a number greater than 1 and less than 51:";

// read input number

cin>>num;

// check input is in between 1-50

if(num<=1||num>50)

{

    cout<<"Invalid input!!"<<endl;

    // exit the program

    exit;

}

else

{

// sum variable

    int sum=0;

    // find sum of all odd numbers

    for(int a=1;a<=num;a++)

    {

        if(a%2!=0)

        sum+=a;

    }

    // print sum

    cout<<"Sum of odd numbers from 1 to "<<num<<" is:"<<sum<<endl;

}

return 0;

}

Explanation:

Read a number from user and assign it to variable "num".If input number

is less than 1 or greater than 50 exit the program.otherwise find the sum

of all odd numbers from 1 to "num".Print the sum of odd numbers.

Output:

Enter a number greater than 1 and less than 51:-5                                                                          

Invalid input!!

Enter a number greater than 1 and less than 51:55                                                                          

Invalid input!!

Enter a number greater than 1 and less than 51:15                                                                          

Sum of odd numbers from 1 to 15 is:64
