Program Generate all possible combinations of 1, 2 & 3

#include<conio.h>

#include<iostream.h>

void main()

{

clrscr();

int a,b,c;

cout<<”All possible combinations are as: “;

for (a=1;a<=3;a++)                                                                                                            

{                   

for (b=1;b<=3;b++)

{

for (c=1;c<=3;c++)

{

                               cout<<a<<" "<<b<<" "<<c<<endl;

}

}

}

getch();

}

Output

All possible combinations are as:

1 1 1       1 2 1       1 3 1

1 1 2       1 2 2       1 3 2

1 1 3       1 2 3       1 3 3

2 1 1       2 2 1       2 3 1

2 1 2       2 2 2       2 2 2

2 1 3       2 2 3       2 3 3

3 1 1       3 2 1       3 3 1 3 1 2       3 2 2       3 3 2 3 1 3       3 2 3       3 3 3

Programe read input and print its table up to giver limit

#include<conio.h>

#include<iostream.h>

void main()

{

clrscr();

long n, l, i;

cout<<"Enter the Number: ";

cin>>n;

cout<<"Enter limit: ";

cin>>l;

for (i=1;i<=l;i++)

{

cout<<n<<"*"<<i<<"="<<n*i<<endl;

}

getch();

}

Output

Enter the Number: 7

Enter limit: 4

7*1=7

7*2=14

7*3=21

7*4=27

Transpose the value by using while loop

#include<conio.h>

#include<iostream.h>

void main()

{

clrscr();

int n,a;

cout<<"Enter number: ";

cin>>n;

cout<<”Transpose of number is: ”;

while (n>0)

{

a=n%10;

n=n/10;

cout<<a;

}

getch();

}

Output

Enter number: 7890

Transpose of number is: 0987
