Debugging Feature of Turbo C++

Debugging Feature of Turbo C++:

·          Turbo C++ is an IDE (integrated development environment) tool. It provides us the facility to create, edit, delete, run, compile, and debugging the programs.

·         Turbo C++ provides many useful Debugging feature. Through these features, We can easily locate logical

·         And syntax errors. Debugging option is provided us a separate menu named Debug in the menu bar. Here is the brief description of these features.

Compiling a single line:

·         TC compiler provides an excellent option to compile the program line by line. This enable the programmer to easily locate errors. For compiling the single line at a time, select run Trace into OR pressing F7 shortcut key.

Watches:

·         Watches or watch expressions are used to check the value of a variable during the program execution. It shows that how and when the value particular variable is change. It is normally in combination with compiling single lines.

Follow the procedure is used to apply the watch or watch expressions.

·         Compile the program line by line through shortcut key F7.

·         During the execution, when control come to  the line that contain required variable, place the cursor on that variable whose value is to be checked.

·         Select debug watch from Menu bar. A sub will appear.

·         Select add watch from the sub menu OR simply use ctrl+F7 shortcut key. A dialog box will appear with selected variable shown in Watch expression field.

·         Click OK or Press Enter. TC sub window shows an error message automatically that shows the current value of the selected variable.

Breakpoints:

It is the most successful and an effective technique of the debugging. A breakpoint is a point in the program where the compiler temporarily stops the program execution, so that the programmer can analyze necessary values. TC provide easy way to use the mechanism for apply the breakpoints. A breakpoint applied through two simple steps:

Place the cursor on the line where you want to apply the breakpoint.

Select Debug Toggle breakpoint OR use Ctrl +F8 shortcut key. Turbo C++ automatically stops the program execution when control reached at that particular line.
