C Functions

The fopen() function in C is a standard library function that opens a file and associates it with a stream. It is part of the C standard library (stdio.h) and is commonly used for file input and output operations.

The fclose() function in C is a standard library function that closes an open file associated with a stream. It is part of the C standard library (stdio.h) and is used to ensure that all data is properly written to the file and resources are freed.

The putchar() function in C is a standard library function that writes a single character to the standard output (stdout). It is part of the C standard library (stdio.h) and is commonly used for simple output operations.

The getchar() function in C is a standard library function that reads a single character from the standard input (stdin). It is part of the C standard library (stdio.h) and is commonly used for simple input operations.

The fputs() function in C is a standard library function that writes a string to the specified stream. It is part of the C standard library (stdio.h) and is commonly used for writing strings to files or the standard output (stdout).

The fgets() function in C is a standard library function that reads a line from the specified stream and stores it into the string pointed to by str. It is part of the C standard library (stdio.h) and is commonly used for reading input from a file or from the standard input (stdin).

The fread() function in C is a standard library function that reads data from a given stream into an array. It is part of the C standard library (stdio.h) and is commonly used for binary file input operations.

The fclose() function in C is a standard library function that closes an open file associated with a stream. It is part of the C standard library (stdio.h) and is used to ensure that all data is properly written to the file and resources are freed.

The fopen() function in C is a standard library function that opens a file and associates it with a stream. It is part of the C standard library (stdio.h) and is commonly used for file input and output operations.

The sscanf() function in C is a standard library function that reads formatted input from a string. It is part of the C standard library (stdio.h) and is used to parse strings according to a specified format.

The sprintf() function in C is a standard library function that writes formatted output to a string. It is part of the C standard library (stdio.h) and is used to format strings without printing them to the console.

The printf() function in C is a standard output function that prints formatted data to the standard output (stdout) stream. It is part of the C standard library (stdio.h) and is widely used to display various types of data on the console.

The scanf() function in C is a standard input function that reads formatted input from the standard input (stdin) stream. It is part of the C standard library (stdio.h) and is commonly used to read various types of data from the user.
