Question

Write a program to do the following:

1. Inputs the values for variables ‘n’ and ‘m’. 

2. Prints the numbers between ‘m’ and ‘n’ which are exactly divisible by ‘m’. 

3. Checks whether the numbers divisible by ‘m’ are odd or even.

OR

Write a program using nested loop that inputs a number ‘n’ which generates an output as follows. Hint: if the value of ‘n’ is 5, the output will be as ‘n’

Answer 1

1. 

25 

25 16 

25 16 9 

25 16 9 4 

25 16 9 4 1

2.

#include<iostream.h>

#include<conio.h>

void main() 

{ 

clrscr(); 

int i,n,m; 

cout<<“Enter values for n and m”;

cin>>n>>m; 

for(i=1;i<=n;i++) 

if(i%m == 0)

cout<<i<<",";

getch();

 } 

3.

#include<iostream.h>

#include<conio.h>

void main() 

{ 

clrscr(); 

int i,n,m; 

cout<<“Enter values for n and m”;

cin>>n>>m; 

for(i=1;i<=n;i++) 

if(i%m == 0)

{

cout<<i<<"\t";

if(i%2 == 0)

cout<<"even"<<endl;

else

cout<<"odd"<<endl;

}

getch();

 }
