Explanation of Solution

Analyzing the given English statement:

The program is to add the two values. Initially declare and initialize with the value to the variables. Then, increment both the variables by 1. Addition operation is performed, finally display the output.

The step by step operations are as follows:

Step1: the “x” variable stores the value of 0.

x = 0

Step2: the “y” variable stores the value of 5.

y = 5

Step3: the variable “x” is incremented by 1.

x = x + 1

x = 0 + 1

x = 1

Step4: the variable “y” is incremented by 1.

y = y + 1

y = 5 + 1

y = 6

Step5: add the value of “x” and “y” and store the result in “y”.

y = x + y

y = 1 + 6

y = 7

Step6: display the output.

The value of “y” is 7

The output for the given statement:

The value of y is 7.
