Using the printf function:

This is the most versatile and frequently used method.
Takes a format string as its first argument and then any number of additional arguments that correspond to placeholders in the format string.
Example:
C
#include

int main() {
printf("Hello, world!\n");
return 0;
}
Use code with caution.

In this example, printf is used to print the message "Hello, world!" to the console. The \n character in the format string represents a newline, which moves the cursor to the beginning of the next line.

You can also use placeholders in the format string to insert variables into the output:

C
#include

int main() {
int age = 25;
char name[] = "Alice";

printf("My name is %s and I am %d years old.\n", name, age);
return 0;
}
Use code with caution.

Here, %s is used to insert the value of name, and %d is used to insert the value of age.

Other methods:

puts: Prints a single string to the console.
fprintf: Prints output to a file instead of the console.
putchar: Prints a single character to the console.
Additional notes:

You can use escape sequences like \n, \t, and \r in the format string to control the output formatting.
For more complex output formatting, consider using the sprintf function to format output into a string first. Using the printf function:
