Structured Programming

Structured Programming

• Structured Programming is the one in which the program is made as a single structure
• It means that the code will execute the instruction by instruction one after the other.
• It doesn’t support the possibility of jumping from one instruction to some other with the help of any statement like GOTO, etc.
• Therefore, the instructions in this approach will be executed in a serial and structured manner.

Example

The languages that support Structured programming approach are:

• C
• C++
• Java

The structured program mainly consists of three types of elements:

• Selection Statements
• Sequence Statements
• Iteration Statements

The structured program consists of well-structured and separated modules. But the entry and exit in a Structured program is a single-time event. It means that the program uses single-entry and single-exit elements. Therefore, a structured program is well maintained, neat and clean program. This is the reason why the Structured Programming Approach is well accepted in the programming world.

Structure of Structed programming

Advantages

• Easier to read and understand
• User Friendly
• Easier to Maintain
• Development is easier as it requires less effort and time
• Easier to Debug
• Machine-Independent, mostly.

Disadvantages

• Since it is Machine-Independent, so it takes time to convert into machine code.
• The program depends upon changeable factors like data-types. Therefore, it needs to be updated with the need on the go.
