C Programming from Scratch: Pointers, Memory and Mini Projects

Learn C the right way for college exams, placements and embedded basics, with clear memory diagrams and console projects

Ghosla Academy · Coding Team

C is the first programming language in most Indian engineering and BCA syllabi, and it is the foundation for data structures, operating systems and embedded work. This course teaches C from zero with short, tested programs and simple memory diagrams so that pointers finally make sense. You will move from your first printf to dynamic memory and file handling, and finish with two console projects you can show in viva exams and placement interviews.

What you will be able to do

  • Install GCC and compile, run and debug C programs from the terminal
  • Use data types, operators, printf and scanf correctly
  • Write programs with conditions, loops, functions and recursion
  • Work with arrays, 2D arrays and strings using string.h
  • Understand pointers, pointer arithmetic and dynamic memory with malloc and free
  • Build structured programs with structs and file handling

What you build

  • Menu-driven calculator with functions
  • Student record system with file storage

What you need to start

  • A laptop (Windows, Linux or Mac) with internet
  • No prior programming experience needed
