Learn C Programming (Beginners to Expert )

Explore increment and decrement operators in C, including prefix and postfix forms, and learn relational operators (==, !=, >, <, >=, <=) and their use in conditions and loops.

Learn to use logical and assignment operators in C, applying relational operators, if statements, increment and decrement, and compound assignments like +=, -=, *=, /=, and %= to control flow.

Learn to control program flow in C using if statements with practical examples, including simple if, if-else, nested if-else, and else-if ladder, demonstrated with an age-check program.

Learn to control program flow with if else statements and nested if statements in C, demonstrated through an age-check example that shows greater than, equal to, and less than conditions.

Learn to use the ternary operator in C to choose between two values based on a binary condition, via condition ? true : false, and return a value.

Learn the goto statement in C, enabling unconditional jumps to labeled points and both forward and backward jumps, with practical examples and notes that it is usually discouraged.

Learn looping in C by mastering while loops, do while, and for loops, using a flowchart and increments to repeat code until a condition ends the loop.

Learn do...while loop in C, which executes body at least once before evaluating the condition, and compare its do { ... } while ( condition ) syntax with while loop.

Master the for loop in C by learning its syntax—initialization, condition, and increment—and see practical examples that print values, run reverse iterations, and explore nested loops for pattern creation.

Master the switch statement in C to handle multiple selections by testing a variable and executing the matching case or default, including a, b, c and uppercase/lowercase variants.

Learn to implement functions in C, including library and user defined functions, with declaration, definition, and calls, and see a simple program that adds two numbers.

Learn how to pass C function arguments by value and by reference, using the address operator to pass pointers and modify original variables.

Learn how to declare, initialize, and access a one-dimensional array in C, using zero-based indexing, for looping over and modifying a collection of same-type elements.

Explore multidimensional arrays in C by declaring and initializing two-dimensional arrays, understanding rows and columns, zero-based indexing, and accessing or modifying elements with nested loops and print statements.

Learn to pass an array as a function parameter in C and sum its elements using a function that accepts the array and its size.

Learn how pointers in C map to memory addresses, declare pointer variables with the address-of operator, and access values through pointers with examples of int, double, float, and char.

Discover strings in C as one-dimensional arrays of characters terminated by null, and learn to declare, print, copy, concatenate, and measure them using string.h functions.

Learn how structures in C act as user defined data types to store mixed data. Use the struct keyword to define, access, initialize, and print struct members.

Explore unions in C, where different data types share one memory location so one member holds a value at a time, and learn to initialize and display int and float.

Learn typedef in C to create aliases for existing data types and user-defined types, simplify complex names, and use typedef with structures to streamline code.

Explore C file input and output by creating, opening, writing, and closing files; learn stream oriented vs system oriented data and practical f open and f close usage.

Learn to read a file in C by declaring a file pointer, opening with fopen, and printing its contents with printf, then closing with fclose.

Explore how enumeration in C defines a user-defined type with enumerators like Monday to Sunday, offering readable, maintainable, zero-based values for days.
