Answer:
Structured programming also known as Modular programming in which the program is made as a single structure.The execution is instruction by instruction.It mainly focuses on improving the quality,clarity and development time of a computer program.
The top-down approach works by breaking a complex algorithm into smaller parts called modules. The modules keep breaking until there is no space left for breaking them without hindering the originality.The breaking of the modules is prohibited after achieving a certain level of modularity . C language uses this approach.
Bottom up works exactly opposite of how the top-down approach works.This approach works in the most elemental level of solving a problem and going up with combination of several parts of the solution to achieve required results.
Answer:
Revisiting "Build a Tower"
Recall in the last section how we made Karel make a tower of tennis balls. We told Karel to move() and turnLeft() and putBall() until we had a tower. At the end of the program, Karel was still at the top of the tower, like as in the picture below.
Stuck at top
Suppose that now we want Karel to come back down from the top of the tower. The first thing we need to do is get Karel facing in the right direction. One way to do this is to tell Karel
turnLeft();
turnLeft();
turnLeft();
And then tell Karel to
move();
move();
move();
back to the bottom of the tower.
However, telling Karel to turnLeft() three times is not very readable. That's a lot of writing when all we really want is to tell Karel to "turn right."
