Coding tips and trick

C Program to Store Information of a Student Using Structure

Example: Accessing Union Members

Difference between unions and structures

Let's take an example to demonstrate the difference between unions and structures:

Access members of a union

Another way of creating union variables is:
union car
{ char name[50];
int price;} car1, car2, *car3;

Create union variables

How to define a union?
union car
{
char name[50];
int price;
};

Now we are starting
"union" in C ,
are you ready for learn
union

Passing struct by reference

Return struct from a function

C Structure and Function..........Passing structs to functions......

Why we study "structs" in C ?

Example of struct👇👇

Access Structure Members
To access members of a structure, use the dot syntax (.):

Syntax of struct
struct structureName {
dataType member1;
dataType member2;..};

C struct
In C programming, a struct (or structure) is a collection of variables (can be of different types) under a single name.

C Program to Find the Frequency of Characters in a String

Example of gets() and puts()

gets() and puts()
Functions gets() and puts() are two string functions to take string input from the user and display it respectively as mentioned

C String 👍Functions

Commonly Used String Functions

Example 4: Strings and Pointers

Example 3: Passing string to a Function

Example 2: fgets() and puts()

Example 1: scanf() to read a string

String initialization in C

Declaration of string

String
In C programming, a string is a sequence of characters terminated with a null character \0. For example:
char c[] = "c string";

Now we are start string in C

Example 3: realloc()

Syntax of realloc()
ptr = realloc(ptr, x);
Here, ptr is reallocated with a new size x.

C realloc()

Example 2: calloc() and free()

Example 1: malloc() and free()

Syntax of free()

free(ptr);

Syntax of calloc():
ptr = (castType*)calloc(n, size);
: Example :
ptr = (float*) calloc(25, sizeof(float));

Example

ptr = (float*) malloc(100 * sizeof(float));
