Chapter 5.6, Problem 7QE

Explanation of Solution

The given program is,

# Initialize Sum is 0

Sum = 0

# Initialize K is 0

K = 0

# Consider N is 10

N = 10

# While loop for iteration

while(K < N):

# Compute K

  K = K+1

# Compute Sum

  Sum = Sum + K

# Display Sum

print(Sum)

In order to ensure the validity of this program, let’s consider the number “N” is “10”.

Explanation:

• In the first step, the program initiates values to variables “Sum” and “K” by “0”.
• The next step is “while” statement along with a condition that says if the value of “K” is less than any number “N”, then execute the block of instructions within the “while” loop.
• The program executes the set of instructions within the “while” statement that says increment the value of “K” and “Sum” subsequently, the value of “K” becomes “1” and the value of $\text{Sum}$ becomes “1” as well
