Question

write a program that prompts the user to enter a length in feet and inches and outputs the equivalent length in centimetres.

Answer 1

import java.util.Scanner;

import java.lang.Math;

class Test

{

public static void main(String[] args)

{

Scanner input=new Scanner(System.in);

System.out.println("Enter Length in Feet:");

int feet= input.nextInt();

System.out.println("Enter Length in Inches:");

int inches= input.nextInt();

double centi=0;

centi=(feet*30)+(inches*2.54);

int c=(int)Math.round(centi);

System.out.println("Centimetres :"+c);

}

}

Output :

Enter Length in Feet:5

Enter Length in Inches:6

Centimetres :165

Answer 2

C program that prompts the user to enter a length in feet and inches and outputs the equivalent length in centimetres is shown below.

• First we convert feet to inches using the formula that 1 feet = 12 inches and then we find total inches.

• Next we convert the total length in inches to cm as 1 inch = 2.54cm.

#include<stdio.h>

int main()

{

 int feet,inches,cm;

 

 printf("Enter the value of feet: ");

 scanf("%d",&feet);

              printf("Enter the value of inches: ");

       scanf("%d",&inches);

 

 //converting into inches

 inches= inches + (feet*12);

               .//converting to cm.

               cm = 2.54*inches

 

 printf("Total value in cm will be: %d\n",cm);

 return 0;

}
