Answer:
I am writing a simple program in C++ However, let me know if you need this program to be implemented in some other programming language .
Program
#include <iostream>
using namespace std;
#define MINUTE_TO_SECOND_FACTOR 60
int main()
{ int minutes;
cout<<"enter the time in minutes: ";
cin>>minutes;
int output;
output = minutes * MINUTE_TO_SECOND_FACTOR;
cout<<minutes<<" minutes = "<<output<<" seconds.";
Output:
enter the time in minutes: 45
45 minutes = 2700 seconds
Step-by-step explanation:
I will explain every line of the code .
- The first statement contains a pre-processor directive which is a library that contains input and output functions for a program.
- The next line namespace is used so that the computer can identify cout, cin and endl used in the program.
- This is a define directive #define MINUTE_TO_SECOND_FACTOR 60
- Here define directive is used for declaring a macro which is MINUTE_TO_SECOND_FACTOR.
- Here this macro is given a value 60.
- Now wherever in the program this macro is used, it will be replaced by 60. This macro MINUTE_TO_SECOND_FACTOR can be used as a constant and cannot be changed.
- Next line enters the body of the main function.
- variable minutes is declared which is used to store the value in minutes.
- variable is declared which will store the result of the conversion from minutes to seconds.
- output = minutes * MINUTE_TO_SECOND_FACTOR; statement works as follows:
In this statement written above the value of minutes is multiplied by 60 ( value of the macro MINUTE_TO_SECOND_FACTOR) and the result of this multiplication is stored in the output variable.
- As we know that 1 minute =60 seconds
- Let suppose the input number is 45 minutes
Then output= 45 * 60
output= 2700 seconds.
- Last statement displays the converted value of minutes into seconds which is stored in output variable.
