To output data in C, you typically use the printf() function from the standard input-output library (stdio.h). Here's how you can use it:

#include

int main() {
// Printing a string
printf("Hello, world!\n");

// Printing integer variables
int num = 10;
printf("The value of num is %d\n", num);

// Printing floating-point variables
float pi = 3.14159;
printf("The value of pi is %.2f\n", pi); // %.2f limits the float to 2 decimal places

// Printing characters
char letter = 'A';
printf("The character is %c\n", letter);

// Printing multiple variables
int a = 5, b = 10;
printf("The value of a is %d and the value of b is %d\n", a, b);

return 0; }

In the printf() function:

%d is the format specifier for integers.
%f is the format specifier for floating-point numbers.
%c is the format specifier for characters.
%.2f specifies that the floating-point number should be displayed with two decimal places.
\n is the newline character, which moves the cursor to the beginning of the next line after printing.

Remember to include the necessary header file #include <stdio.h> at the beginning of your code to use the printf() function.
