Skills You Will Learn

Explain the role of C in computer programming and distinguish between natural and programming languages. Write, compile, and run basic C programs. Work with data types including integers, floating-point numbers, characters, and the void type. Apply arithmetic, logical, and relational operators. Use formatted input/output to control data presentation. Apply conditional execution using if-else and switch statements. Implement loops for repetitive program flow. Perform type conversions and understand computer logic fundamentals. Declare and manipulate arrays (vectors) including arrays of different data types. Sort data using sorting algorithms. Use initiators to simplify array initialization. Work with pointers, understand pointer arithmetic, and compare pointers and arrays. Declare, assign, and process strings in C. Implement multidimensional arrays and arrays of pointers. Apply dynamic memory management using malloc() and free(). Define and call user-defined functions with variables, parameters, and return values.
