Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
void switch_fun(int input)
{
//array to store binary of input number
int bin[7];
// convert the number into binary
for(int i=0; input>0; i++)
{
bin[i]=input%2;
input= input/2;
}
// print the switch number and their status
cout<<"Switch number:\t 1\t 2\t 3\t 4\t 5\t 6\t 7 \n";
cout<<"status: ";
for(int j=6;j>=0;j--)
{
// if bit is 1 print "ON" else print "OFF"
if(bin[j]==1)
cout<<"\t ON";
else
cout<<"\t OFF";
}
}
int main()
{
int n;
cout<<"enter the number between 1-100 only:");
// read a number in decimal
cin>>n
// validate the input
while(n<1 ||n>100)
{
cout<<"wrong input!! Input must be in between 1-100:"<<endl;
cout<<"enter the number again :";
cin>>n;
}
// call the function with input parameter
switch_fun(n);
return 0;
}
Explanation:
Read a decimal number from user. If the number is not between 1 to 100 the it will again ask user to enter the number until the input is in between 1-100.Then it will call the fun() with parameter n. First it will convert the decimal to binary array of size 7.Then print the status of switch.If bit is 1 then print "ON" else it will print "OFF".
Output:
enter the number between 1-100 only:-5
wrong input!! Input must be in between 1-100:
enter the number again :125
wrong input!! Input must be in between 1-100:
enter the number again :45
Switch number: 1 2 3 4 5 6 7
Status: OFF ON OFF ON ON OFF ON
