Question

Write a program that prompts the user to enter a floating point number. Then ask them if they want to print the value using 1 digit of precision or 4. Add some error checking that alerts the user if they enter an invalid choice (not 1 or 4).

Example #1 Please enter a floating point number: 23.789456

Do you want to print with 1 or 4 digits of precision (Enter 1 or 4): 4 23.7890

Example #2 Please enter a floating point number: 23.789456

Do you want to print with 1 or 4 digits of precision (Enter 1 or 4): 1 23.7

Example #3 Please enter a floating point number: 23.789456

Do you want to print with 1 or 4 digits of precision (Enter 1 or 4): 3 That is not a valid choice!

Explanation / Answer

this is a simple program which will take input as a floating value and print it with your choice of precisions

#include<stdio.h>
#include<iostream.h>
#include<conio.h>

#include<stdio.h>
#include<conio.h>

void main()
{
   float number=0;
   int choice=0;
   clrscr();
   printf(" Hello sir pls enter a floating point number");
   scanf("%f",&number);
   printf(" Your entered number is %f",number);
   printf(" do you want to print the value using 1 digit of precision or 4 digit of precision..(enter 1 or 4)");
   scanf("%d",&choice);
   printf(" %d",choice);
   if(choice==1)
       printf(" your %d digit precision number is %10.1f",choice,number);
   else if(choice==4)
       printf(" your %d digit precision number is %10.4f",choice,number);
   else
       printf(" this is not a valid choice.. pls enter 1 or 4 only ");
   getch();
}

this code gets executed on turbo c++ compiler with perfect results.

thank you.
