PROGRAM 1
#include <iostream>
using namespace std;
int main() {
int n;
// user input taken for n
cout<<"Enter any number greater than five: ";
cin>>n;
cout<<"The multiples of 5 between 1 to "<<n<<" are shown below."<<endl;
// displaying multiples of 5 between 1 to n
for(int h=1; h<=n; h++)
{
// if number is completely divisible by 5, remainder will be 0
if( (h%5)==0)
cout<<h<<endl;
}
return 0;
}
OUTPUT
Enter any number greater than five: 22
The multiples of 5 between 1 to 22 are shown below.
5
10
15
20
The program does not implements any input validation since this is not mentioned in the question.
User input is taken. All the multiples of 5 computed inside a for loop, and displayed to the console.
PROGRAM 2
#include <iostream>
using namespace std;
int main() {
// variables to hold respective values
int n;
int sum=0;
double avg=0;
do
{
// user input taken for n
cout<<"Enter any number between 1 and 100: ";
cin>>n;
if(n<1 || n>100)
cout<<"Invalid number. Enter valid number."<<endl;
cout<<""<<endl;
}while(n<1 || n>100);
// computing sum and average of numbers from 1 to n
for(int h=1; h<=n; h++)
{
sum = sum+h;
}
avg=avg+(sum/n);
cout<<"Sum of all the numbers from 1 to "<<n<<" is "<<sum<<endl;
cout<<""<<endl;
cout<<"Average of all the numbers from 1 to "<<n<<" is "<<avg<<endl;
return 0;
}
OUTPUT
Enter any number between 1 and 100: 111
Invalid number. Enter valid number.
Enter any number between 1 and 100: 0
Invalid number. Enter valid number.
Enter any number between 1 and 100: 23
Sum of all the numbers from 1 to 23 is 276
Average of all the numbers from 1 to 23 is 12
The program not implements any input validation since this is mentioned in the question.
User input is taken inside do-while loop till valid input is obtained.
The sum of all numbers from 1 to n computed inside a for loop, average computed outside for loop.
Both values are displayed to the console.
