meters = cms / 100;

meters_tf.setText(df.format(meters));

inch_tf.setText(df.format(inches));

yards_tf.setText(df.format(yards));

}

Explanation:

Inside the action performed method, pass the strings in text box.
check if the value has been modified then do the relevant conversions inside the conditional statement.
When the user clears, it will not do to the inch conversion.

g Write a program that prompts the user for an integer n between 1 and 100. If the number is outside the range, it prints an err

grin007 [14]

Answer:

The cpp program is given below.

#include<iostream>

#include<iomanip>

using namespace std;

int main() {

// variables declared

int n;

int sum=0;

float avg;

do

{

// user input taken for number

cout<< "Enter a number between 1 and 100 (inclusive): ";

cin>>n;

if(n<1 || n>100)

cout<<" Number is out of range. Enter valid number."<<endl;

}while(n<1 || n>100);

cout<<" "<<endl;

// printing even numbers between num and 50

for(int num=1; num<=n; num++)

{

sum = sum + num;

}

avg = sum/n;

// displaying sum and average

cout<<"Sum of numbers between 1 and "<<n<<" is "<<sum<<endl;

cout<<"Average of numbers between 1 and "<<n<<" is ";

printf("%.2f", avg);

return 0;

}

OUTPUT

Enter a number between 1 and 100 (inclusive): 123

Number is out of range. Enter valid number.

Enter a number between 1 and 100 (inclusive): 56

Sum of numbers between 1 and 56 is 1596

Average of numbers between 1 and 56 is 28.00

Explanation:

The program is explained below.

1. Two integer variables are declared to hold the number, n, and to hold the sum of numbers from 1 to n, sum. The variable sum is initialized to 0.

2. One float variable, avg, is declared to hold average of numbers from 1 to n.

3. User input is taken for n inside do-while loop. The loop executes till user enters value between 1 and 100. Otherwise, error message is printed.

4. The for loop executes over variable num, which runs from 1 to user-entered value of n.

5. Inside for loop, all the values of num are added to sum.

sum = sum + num;

6. Outside for loop, average is computed and stored in avg.

avg = sum/n;

7. The average is printed with two numbers after decimal using the following code.

printf("%.2f", avg);

8. The program ends with return statement.

9. All the code is written inside main() and no classes are involved.
