he chapter starts with the introduction of strings which is nothing but at an array of characters terminated with null character. In the introduction part definition of string, declaration and defining them in C is given. The next section follows presents number of programming examples of strings which makes your concepts of strings better.

Array of strings is covered in section 8.3 with lots of programming examples. Small programs like reading and displaying the array of strings are given, program for sorting the string and many other programs are covered.

Discussion of few built-in library functions for string manipulation is presented in the last section. The most frequently used functions for string manipulation are covered only. A brief idea of other useful functions is given in the form of tables for the user so he can check out the functions by referring Turbo C help.

Testing of Concrete

The need for non-destructive testing (NDT) of concrete may arise due to variety of reasons.

These are: assessment of structural integrity or safety following material deterioration, structural damage caused by fire, fatigue or overload, adequacy of members suspected to contain unspecified material, fault in design, and monitoring long term changes in material properties and structural performance. NDT is generally defined as not impairing the intended performance of element or member under test, and when applied to concrete is taken to include methods which cause localized surface zone damage. All NDT methods can be performed directly on the in-situ concrete without removal of a sample.

Broadly speaking, there are two classes of NDT methods. The first class consists of those methods that are used to estimate strength. The surface hardness, penetration resistance, pullout, pull-off, break-off, and maturity techniques belong to this category. Some of these are not truly

Photogrammetric surveying or photogrammetry is the science and art of obtaining accurate measurements by use of photographs, for various purposes such as the construction of planimetric and topographic maps, classification of soils, interpretation of geology, acquisition of military intelligence and the preparation of composite pictures of the ground. The photographs are taken either from the air or from station on the ground. Terrestrial photogrammetry is that branch of photogrammetry wherein photographs are taken from a fixed position on or near the ground.

Aerial photogrammetry is that branch of photogrammetry wherein the photographs are taken by a camera mounted in an aircraft flying over the area. Mapping from aerial photographs is the best mapping procedure yet developed for large projects, and are invaluable for military intelligence. The major users of aerial mapping methods are the civilian and military mapping agencies of the Government.

Using the Accept and Discard Buttons

When you enter information in the editor, the previous and next buttons change to accept and discard. Click Accept to save information. Click Discard to discard information.

Events Creation

An event is made up of an expression and an action. When the expression changes from false on the previous evaluation to true on the current evaluation, the action is triggered. The following illustration shows an event file.

1. In the Action field, type an RSView32 command, a macro, or a symbol that will run when the expression goes from false to true.

2. To disable the event, clear the Enabled check box. When the event file runs, this disabled event will not be evaluated.

3. In the Description field, type a brief description to document the event�s function.

4. In the Expression area, create an expression to specify the conditions that will trigger the action.
