Type casting in C

If I understand, converting one type to another type is type casting in c laguage

Code:

---

#include<stdio.h>

int main()
{
    char a = 'A';




    void *ptr = &a;




    printf("%c \n", *(char *)ptr);
       
    *((char *)ptr) = 'B';
       
        printf("%c", *(char *)ptr);




    return 0;
}

Is the type casting happeing in the code ? in which line type casting is happning ?

Anytime you see "(Type)" or "(Type *)" these are a cast to the type in the parentheses. In lines 15, 17, and 19 you are converting a "void *" to a "char *" pointer.

Also, please remove most of the blank lines. One is sufficient.

Is this a homework assignment? If not, where is this code from? If it came from a book or web site, you'd think it would explain type casting and show code like that as an example.

If you are attempting to learn from painfully inadequate online tutorials, YouTube videos, or some book claiming to teach you in a short time, then THROW THEM AWAY!

Short of taking a course in C Programming from a qualified instructor, you need to study a good book on the C Programming Language, cover to cover, and do all the exercises at the end of each chapter! Choose one of the three listed below:

C Programming, A Modern Approach
Author: K. N. King

C Primer Plus, 6th Edition
Stephen Prata

C How to Program, 8/e
Deitel & Deitel

Studying one of these books, and writing code, you will have a much better understanding of the C Programming language.
