C Printf

C printf

Created By: chatGPT

C's printf function is part of the C standard library and allows you to output formatted text to the console. This function is extremely versatile and can be used to display strings, integers, floating-point numbers, and more.

#include <stdio.h>

int main() {
    int number = 10;
    float pi = 3.14;
    char *text = "Hello, World!";

    printf("Integer: %d\n", number);
    printf("Float: %.2f\n", pi);
    printf("String: %s\n", text);

    return 0;
}

Format specifiers are used in the printf function to define the type of data being printed. For example, %d is used for integers, %f for floating-point numbers, and %s for strings.

printf("int: %d\n", num);
printf("float: %f\n", decimal);
printf("string: %s\n", str);

You can also control the width and precision of the output. For example, specifying a width will adjust how much space the number takes when it is printed.

printf("%5d\n", 42); // prints '  42' (4 spaces before 42)
   
printf("%.2f\n", 3.14159); // prints '3.14'

To print multiple variables, simply insert additional arguments into the printf function corresponding to each format specifier.

int a = 5, b = 10;
printf("a: %d, b: %d\n", a, b);

Escape sequences are sequences starting with a backslash (\) that allow you to format the output. Common escape sequences include \n for new line and \t for tab space.

printf("Hello,\nWorld!\n"); // Outputs 'Hello,' on one line and 'World!' on the next
