Question

C++

Write a function named “hasDescendingDigits” that accepts a string of numbers. It
returns true if the string contains the digits in descending order. The function can
ignore (e.g. skip checking) all the characters that are not digits in the string. Empty
string will return false.
For example, string of “95421” or “862” or “8622” or “88” or “9” will return true and
string of “95423” or “889” or “9445” or “449” or “” will return false.

Answer 1

main.cpp

#include<iostream>

using namespace std;

bool hasDescendingDigits(int n)

{

int wh = n%10;

while (n / 10 > 0)

{

n /= 10;

if (wh > n % 10)

{

return false;

}

wh = n % 10;

}

return true;

}

int main()

{

  int n;

cout<<"Enter numbers without spaces: ";

   cin>>n;

cout<<hasDescendingDigits(n)<<endl;

return 0;

}

Output:

Enter numbers without spaces: 95421 1

Enter numbers without spaces: 449 00
