The program should then declare a fourth variable sum, and assign the sum of num 1 and num 2 to the variable sum. Lastly, the values of num 1 and sum should be displayed.

Explanation / Answer

Give an example of:

i. Expression. 2+3*4

ii. Assignment Statment. variable = 2+3*4;

iii. Conditional Expression.

if(variable < 10):
print variable;

What is the value of the following expressions:
i. 1/2 0

ii. 20 - 4 * 8 + 2 -10

Code for your requirement.

num2 = -32;           #initialize num2 to -32.
name = "Simon";       #initialize name to Simon.
sum = num1 + num2;   #assign num1 + num2 to sum.
print "num1: ", num1;   #display num1 value.
print "sum : ", sum;    #display sum value.
