Example

Using functions like printf() and scanf() to handle user input and display output.

Scenario

In a console application, printf() can be used to display text and variables to the screen, while scanf() allows the program to receive user input. For instance, in a simple calculator application, printf() might be used to display a prompt for the user to enter two numbers, and scanf() would read these numbers for subsequent operations.

Example

Functions like malloc(), calloc(), realloc(), and free() to dynamically allocate and deallocate memory.

Scenario

In a program that requires dynamic data structures like linked lists or trees, malloc() can be used to allocate memory for new nodes as needed. After processing, free() is used to deallocate memory to avoid memory leaks. For example, a dynamic array implementation might use realloc() to resize the array as elements are added.

Example

Functions like fopen(), fread(), fwrite(), and fclose() to perform file operations.

Scenario

In a data processing application, fopen() can be used to open a file containing data to be read. fread() reads the data into memory, where it can be processed, and fwrite() might be used to write results back to a file. For instance, a program that processes student records might read data from an input file, sort the records, and write the sorted data to an output file.
