Question

    Design a class to overload a function num_calc as follows:

    a. void num_calc(int num, char ch)    with one integer argument and one character argument , computes the square of integer argument if choice ch is

    ‘s’ otherwise find its cube.

    b. void num_calc(int a,int b, char ch) with two integer arguments and one character argument if ch is ‘p’ multiply else adds the integers.

    c. void num_calc(int s1, int  s2) with two integer arguments, which prints whether the integers are equal or not.

​

Design a class to overload a function num_calc as follows:

1. void num_calc(int num, char ch)    with one integer argument and one character argument , computes the square of integer argument if choice ch is 's’ otherwise find its cube.
2. void num_calc(int a,int b, char ch) with two integer arguments and one character argument if ch is ‘p’ multiply else adds the integers.
3. void num_calc(int s1, int  s2) with two integer arguments, which prints whether the integers are equal or not.

class Overload

{

void num_calc(int num, char ch)

{

if(ch=='s')

num*=num;

else

num*=num*num;

System.out.println("Result is: "+num);

}

void num_calc(int a, int b, char ch)

System.out.println("Numbers are equal.");

else

System.out.println("Numbers are not equal.");

}

public static void main(String args[])

{

Overload obj=new Overload();

obj.num_calc(5,'s'); // computes square of 5.

obj.num_calc(5,10,'p'); //find the product of 5 and 10.

obj.num_calc(5,10); //prints that both are not equal.

}

Result is: 25

Result is: 50

Numbers are not equal.
