Question

1) Write Single-line comments for each code in programming C++

2) Prompt the user to enter a number from 1 to 100, inclusive. If the number is not valid, meaning out of range, then indicate that the number is not valid and that they should try again. This program should test for negative numbers, which are not valid. Prompt the user to indicate that the number must be greater than 0 and that they should try again. If the number is greater than 100, then indicate that the number must be equal to or less than 100. If the number valid, then indicate to the user that the number is valid.

Answer 1

input code:

output:

code:

#include <bits/stdc++.h>
using namespace std;

int main()
{
//initialize variables
int numbers;
cout<<"Enter the number between 1 to 100:";
a: //define label for use in goto
//take input from user
cin>>numbers;
  
//check number is between 1 to 100 or not
if(numbers>=1 && numbers <=100)
{
//if true than print this
cout<<"the number is valid."<<endl;
}
//check numbers is less than 0 or not.
else if(numbers<=0)
{
//if true than print this and goto label a
cout<<"the number must be greater than 0.Please try again.:";
goto a;
}
//check numbers is less than 0 or not.
else if(numbers>100)
{
//if true than print this and goto label a
cout<<"the number must be equal to or less than 100.Please try again.:";
goto a;
}
return 0;
}
