Question

Problem 1: Write a program that reads a positive float number and displays the previous and next integers. Sample Run: Enter a float: 3.5 The previous and next integers are 3 and 4.

Problem 2: Write a program that reads two integers and displays their sum, difference, product, and the result of their division. Sample Run: Enter two integers: 8 5 Sum: 8, Difference: 3, Product: 40, Division: 1.6

Problem 3: Write a program that reads a three-digit integer from the keyboard and prints out the sum of its digits. The number entered by the user is guaranteed to be three-digit and will not start from a zero. You can use divisions by powers of 10 to isolate each of the digits. Sample Run: Enter an integer: 358 The digit sum of 358 is: 16

Problem 4: Write a program that reads a number that represents seconds and converts it into hours, minutes, and seconds. Sample Run: Enter the time in seconds: 8140 8140 seconds equal 2h, 15m, and 40s

Answer 1

Note:

As U didnt mentioned In which language you want me to develop ,I developed in c++.Plz tell me if u need this in Java ,Python,or c
Could you plz go through this code and let me know if u need any changes in this.Thank You
=================================

1)

#include <fstream>
#include <iostream>
#include <iomanip>
#include <cmath>

using namespace std;

int main() {
   //Declaring variables
float a;
  
   cout<<"Enter a float :";
   cin>>a;
  
   cout<<"The previous and next integers are "<<floor(a)<<" and "<<ceil(a)<<endl;
  
   return 0;
}

========================

Output:

================================

2)

#include <fstream>
#include <iostream>
#include <iomanip>
#include <cmath>

using namespace std;

int main() {
   //Declaring variables
int a,b;
  
   cout<<"Enter two integers :";
   cin>>a>>b;
  
   cout<<"Sum :"<<(a+b)<<endl;
   cout<<"Difference :"<<(a-b)<<endl;
   cout<<"Product :"<<a*b<<endl;
   cout<<"Division :"<<(float)a/b<<endl;
     
   return 0;
}

Output:

===============================

3)

#include <fstream>
#include <iostream>
#include <iomanip>
#include <cmath>

using namespace std;

int main() {
   //Declaring variables
int a,sum=0;
  
   cout<<"Enter a number :";
   cin>>a;
  
   while(a>0)
   {
       sum+=a%10;
       a=a/10;
   }
  
   cout<<" Sum of digits :"<<sum<<endl;
  
     
   return 0;
}

Output:

=============================

4)

#include <fstream>
#include <iostream>
#include <iomanip>
#include <cmath>

using namespace std;

int main() {
   //Declaring variables
int secs,hours,mins;
  
   cout<<"Enter the time in seconds: ";
   cin>>secs;
  
hours=secs/3600;
secs%=3600;
mins=secs/60;
secs%=60;
  
   cout<<secs<<" seconds equal "<<hours<<"h, "<<mins<<"m, and "<<secs<<"s"<<endl;

   return 0;
}

=====================Could you plz rate me well.Thank You
