0 What are the Limitations of Structured Programming?

In structured programming, focus is on the algorithm and importance is given to the procedure (logic) and not to the data on which these procedures operate.
The entire problem was divided into a number of smaller units Functions or Procedures.
All these units need to work on a data item to produce the result.
The data need to be global,Global data makes the code complex.
As the code size grows, maintaining code becomes difficult, sometimes impossible.
