Searching and Sorting in C Programming

Searching

This is the process by which one searches the group of elements for the desired element. For example:

Binary Search

In binary search the basic requirement is the elements of the array should have been sorted alphabetically or numerically in the ascending order.

File Processing in C Programming

In industry, most of the programs are written to store the information is taken from the program. One such way is to store the fetched information in a file. File is created for permanent storage of data.

C have a lot of functions that helps to perform basic file operations. Here is that table of functions.

this table is taken from www.studytonight.com

For opening file or creating a file we can use fopen() function. For closing file we can use fclose() function. In this function, we need a pointer to run this function.

Struct and Union in C Programming

Struct

Struct is a user-defined datatype in C language which allows us to combine data of different types together.

Union

Like Struct, union is a user-defined datatype. In union, all members share the same memory location.

so this picture shows the difference and the form between Struct and Union

Function - Recursion in C Programming & Cloud Computing

Function

 return_value_type function name ( parameter-list )

{ 

  statements;

}

⇒If return-value-type is void then the function will not return value.

Pointer and Array in C Programming

Pointer

used to keep addresses of case or integer and to access the memory or setting the address. like any variabel constant , you must declare a pointer before using it to store any variable address.

Program Control - Repetition

For

//for(case1; case2; case3) statements;

For used when we want to do looping for a certain number of times.

don't forget to check the case because if we don't check the case, the program can be run with invinite looping.
