Give an example of an if/else statment and a case statment that are equivalent. Your example should contain at least three choic

zimovet [89]

Answer:

The if - else and equivalent switch case statements in c++ language are given below.

if ( ch == 1 )

cout << " sum is " << x + y << endl;

else if ( ch == 2 )

cout << " difference is " << x - y << endl;

else if ( ch == 3 )

{

cout << " Quitting " << endl;

exit;

}

switch( ch )

{

case 1 : cout << " Sum is " << x + y << endl;

break;

case 2 : cout << " Difference is " << x - y << endl;

break;

case 3 : cout << " Quitting " << endl;

break;

}

Explanation:

The above statements use three variables which are declared and initialized as shown.

int x = 10;

int y = 25;

int ch;

The above statements execute for of addition, subtraction or to quit the program.

cout << " 1. Addition " << endl;

cout << " 2. Subtraction. " << endl;

cout << " 3. Quit " << endl;

cout << " Enter your choice " << endl;

The variable ch holds the numerical option entered by the user.

cin >> ch;

For if - else statements, the if statement is executed based on the value of variable ch entered by the user. After execution, the compiler goes out of the statements automatically.

Following the if – else, if any statement is present, it will be executed.

For switch case, every case ends with break keyword. After the required case is executed based on the value of variable ch entered by the user, the break statement is executed which causes the switch case to terminate the control goes out of the statements.

Following the switch case, if any statement is present, it will be executed.

Which of the following statements about global variables is true? 1.A global variable is accessible only to the main function. 2

Korvikt [17]

Answer:

A global variable can have the same name as a variable that is declared locally within the function.

Explanation:

In computer program, we refer to a global variable as that variable that comes with a global perspective and scope, ensuring its visibility throughout the program, except it is shadowed. The set of this kind of variable is referred to as global state or global environment. One feature of global environment is that it can have similar name as a variable declared locally within the function.

Write Python algebraic expressions corresponding to the following statements: (a) The sum of the first five positive integers (b

lbvjy [14]

Answer:

#part a

#sum of first 5 positive number

Sum=5*(5+1)/2

print("sum of first 5 positive integer is: ",Sum)

#part b

# declare age of all

Sara_age=23

Mark_age=19

Fatima_age=31

ave_age=(Sara_age+Mark_age+Fatima_age)/3

print("average age of Sara,mark and Fatima is: ",ave_age)

#part c

#find number of times

no_of_times=int(403/73)

print(" number of times when 73 goes into 403 is: ",no_of_times)

#part d

#find remainder

rem=403%73

print("when 403 is divided by 73 then remainder is: ",rem)

#part e

#calculate 2 to pawer 10

two_pow=2**10

print("2 to power 10 is: ",two_pow)

#part f

#declare height of both

sara_h=54

mark_h=57

diff_h=abs(sara_h-mark_h)

print("The absolute difference between height of Sara and Mark is: ",diff_h)

#part g

#find the minimum among three

print("lowest price among the three($34.99,$29.95,$31.50) is: $",min(34.99,29.95,31.50))

Explanation:

In part a, sum of first 5 positive number is calculated as 5*(5+1)/2.In part b, add the age of three and divide it by 3. In part c, use "/" to find number of times 73 goes into 403.In part d, use "%" to find remainder when 403 is divide by 73.In part e, 2 to the 10th power is calculated as 2**10.In part f, use abs() to find the absolute difference.In part g, min() function is used to find lowest among the 3 prices.

Output:

sum of first 5 positive integer is: 15.0

average age of Sara,mark and Fatima is: 24.333333333333332

number of times when 73 goes into 403 is: 5

when 403 is divided by 73 then remainder is: 38

2 to power 10 is: 1024

The absolute difference between height of Sara and Mark is: 3

lowest price among the three($34.99,$29.95,$31.50) is: $ 29.95
