In general the lap and wave winding consists of a number of coils connected in series and number of such series circuits are connected in parallel. The coils are diamond shaped and are made in special forming machines. The coils may be single turn or multi turn coil, and a turn consists of two conductors.

It is likely that we discover later, the previously allocated memory is not sufficient and we need additional space for more elements. It is also possible that the memory allocated is much larger than necessary and we want to reduce it. In both the cases, we can change the memory size already allocated with the

calloc in c is another memory allocation function that is normally used for requesting memory space at run time for storing derived data types such as arrays and structures. While malloc allocates a single block of storage space, calloc in c allocates multiple blocks of storage, each of the same size, and then sets all

We can access and assign values to the accessing structure members in a number of ways. As mentioned earlier, the members themselves are not variables. They should be linked to the structure variables in order to make them meaningful members. For example, the word title, has no meaning whereas the phrase ‘title of book3’ has

We use arrays structures to describe the format of a number of related variables. For example, in analyzing the marks obtained by a class of students, we may use a template to describe student name and marks obtained in various subjects and then declare all the students as structure variables. In such cases, we may

Variables in C differ in behavior from those in most other languages. For example, in a BASIC program, a variable retains its value throughout the program. It is not always the case in C. It all depends on the ‘storage’ class a variable may assume. In C not only do all variables have a data

C permits nesting of function in c freely. main can call function1, which calls function2, which calls function3, ….. and so on. There is principle no limit as to how deeply functions can be nested. Consider the following program float ratio (int x, int y, int z); int difference (int x, int y); main() {

Like the values of simple variables, it is also possible to pass the values of an array to a function. To passing arrays to function in C a one dimensional an array to a called function, it is sufficient to list the name of the array, without any subscripts, and the size of the array

Like variables, all functions in a C program must be declared, before they are invoked. A function declaration (also known as function prototype) consists of four parts. Function type (return type) Function name Parameter list Terminating semicolon They are coded in the following formate : Function-type function-name (parameter list); This is very similar to the

Definition of Function in C A function definition, also known as function implementation shall include the following elements 1. function name; 2. function type; 3. list of parameters; 4. local variable declarations; 5. function statements; and 6. a return statement. All the six elements are grouped two parts, namely, ♦ function header (First three elements);and
