Exercise Solutions – NCERT Solutions Computer Science Chapter 6 Flow Of Control (2025-26)

1. What is the difference between else and elif construct of if statement?

Answer: The else construct is used to specify a block of code that runs when all preceding if and elif conditions are false. It does not check any condition. The elif construct (short for "else if") is used to check multiple conditions sequentially after the initial if; each elif has its own condition to check.

2. What is the purpose of range() function? Give one example.

Answer: The range() function in Python is used to generate a sequence of numbers, primarily used for iterating through loops. For example: for i in range(3, 7): print(i) outputs: 3, 4, 5, 6.

3. Differentiate between break and continue statements using examples.

Answer: The break statement immediately terminates the nearest enclosing loop, skipping any remaining iterations. For example:
for i in range(5): if i == 3: break; print(i) prints 0 1 2.
The continue statement skips the rest of the code inside the loop for the current iteration and continues with the next iteration. For example:
for i in range(5): if i == 3: continue; print(i) prints 0 1 2 4.

4. What is an infinite loop? Give one example.

Answer: An infinite loop is a loop that runs endlessly because its termination condition is never met. For example: while True: print('Hello') will keep printing 'Hello' without stopping unless interrupted externally.

5. Find the output of the following program segments:

(i)

a = 110

while i < 9:
    if i % 4 == 0:
        sum = sum + i
    i = i + 2
print(sum)

Answer: 12

(v)

for x in range(1,4):
    for y in range(2,5):

    print ('Current variable value: ', var)
    var = var -1
    if var == 3:
        break
else:
    if var == 6:
        var = var -1
        continue
