b. They are difficult to understand.
c. They make it easy to identify errors.
d. They are not effective for problem-solving.
B. Fill in the blanks using the words given below:
Control structure, Diamond, Sequential, True, Start
1. .............................. shape is used to represent decision making in case of branching or looping
in a flowchart.
2. If the condition is .............................., a certain block of instructions is executed.
3. .............................. is the simplest form of control structure, where instructions are executed
in an order, one after the other.
4. .............................. is defined as an order of execution of a statement in an algorithm.

1. Visuals have more impact on the human brain as compared to text. ....................
2. Flowcharts are effective in analysing and solving problems but are not used
in preparing documentation of software. ....................
3. Algorithms are difficult to find errors in, whereas flowcharts make it easy to
identify errors. ....................
4. Both algorithms and flowcharts can represent branching and looping, but
flowcharts do so more easily through symbols. ....................
