What is modular programming? Mention any four advantages of modular programming.

Modular programming is a programming technique in which a program is divided into many small logical, manageable and functional parts.

Any four advantages of modular programming are listed below:
1) The same procedure can be used more than once without rewriting it. So, it reduces the length of the program.
2) Individual procedure can be written independently so;it is suitable for a teamwork.
3) The debugging of the program becomes easier and faster.
4) The procedure can be tested and...

Define control structure. Explain different types of control structure.

Control Structuresare just a way to specify flow of control in programs. Any algorithm or program can be more clear and understood if they use self-contained modules called as logic or control structures. It basically analyzes and chooses in which direction a program flows based on certain parameters or conditions.

1. Sequential Logic (Sequential Flow)

   Sequential logic as the name suggests follows a serial or sequential flow in which the flow depends on the series of instructions given to the...

Define functions. Write the advantages of function with program example.

Afunctionis basically a block of statements that performs a particular task. Suppose a task needs to be performed continuously on many data at different points of time, like one at the beginning of the program and one at the end of the program, so instead of writing the same piece of code twice, a person can simply write it in a function and call it twice. And after the execution of any function block, the control always comes back to themain()function.

Here are several advantages of using...
