Answer:

C code :

#include<stdio.h>

int main()

{

int j;

float k,l, x;  //taking float to give the real results.

printf("Enter your two operands: ");  //entering the numbers on which      //the operation to be performed.

scanf("%f %f", &k, &l);

 

printf("\n Now enter the operation you want to do: ");

printf("1 for Addition, 2 for Subtraction, 3 for Multiplication, 4 for Division ");

scanf("%d", &j);  //j takes the input for opearation.

 

switch(j)  

{

 case 1:  

  x=k+l;

  printf("%.2f+%.2f=%.2f",k,l,x);   //we write %.2f to get the result //upto 2 decimal point.

  break;

   

 case 2:

  x=k-l;

  printf("%.2f-%.2f=%.2f",k,l,x);

  break;

 case 3:

  x=k*l;

  printf("%.2f*%.2f=%.2f",k,l,x);

  break;

 case 4:

  if(l!=0) //division is not possible if the denominator is 0.

  {

   x=k/l;

   printf("%.2f/%.2f=%.2f",k,l,x);

  }

  else  

   printf("Division result is undefined");

               default:

   printf("\n invalid operation");

}

}

Output is in image.

Explanation:

At first we take two numbers.

Then we take integers from 1 to 4 for Addition, subtraction, multiplication, division respectively.

Then accordingly the case is followed and the operation is performed.

Write a statement that defines a double variable named result, initialized with the value 6.759.
In-s [12.5K]

Answer:

"double result=6.759;" is the correct answer for the above question.

Explanation:

  • In c-programming language, the double is a data type which stores the decimal value up to 6 decimal point.
  • This data type takes 8 bytes space in memory when it is used in the c-programming language.
  • When the user wants to declare the double data type, then he should need to declare by the help of the following syntax-- double variable_name_or _identifier_name;
  • When the user wants to declare the double data type and initialize the value on its then he can do this with the help of the following syntax--double variable_name_or _identifier_name= value_which_needs_to_store;
  • The above question asked the one-line statement which declares the result variable of double data type and initializes the "6.759" value on its then he can do this by the help of "double result=6.759;" statement which is described above. Hence the answer is "double result=6.759;".

int nob=sc.nextInt();

ModifiedPayroll obj=new ModifiedPayroll(salary,nob);

obj.printOutput();

}

}

Explanation/Output:

// For Payroll.java

State Tax: $350.0

Federal Tax: $81.25

Dependents: $62.5

Salary: $1250.0

Take Home Pay: $881.25

// For ModifiedPayroll.java

Enter Salary:$1550.0

Enter number of Dependents:$3

State Tax: $434.0

Federal Tax: $100.75

Dependents: $116.25

Salary: $1550.0

Take Home Pay: $1131.5
