Printing to the Console in C programming

Printing to the Console in C

In C programming, you can print output to the console using the printf function from the <stdio.h> library. The function allows you to format and display text and variables.

Syntax

printf("format string", arguments);

Where format string specifies how the output should be formatted, and arguments are the values to be printed.

Common Format Specifiers

• %d: For integers
• %f: For floating-point numbers
• %c: For characters
• %s: For strings

Example Code

Here’s a simple example of using printf:

#include <stdio.h>

int main() {
    int age = 25;
    float height = 5.9;
    char initial = 'J';
    char name[] = "John Doe";

    // Print an integer
    printf("Age: %d\n", age);

    // Print a floating-point number
    printf("Height: %.1f feet\n", height);

    // Print a character
    printf("Initial: %c\n", initial);

    // Print a string
    printf("Name: %s\n", name);

    return 0;
}

This code demonstrates printing different types of data using printf:

• printf("Age: %d\n", age); prints the integer variable age.
• printf("Height: %.1f feet\n", height); prints the floating-point variable height with one decimal place.
• printf("Initial: %c\n", initial); prints the character variable initial.
• printf("Name: %s\n", name); prints the string variable name.

Note:
Use format specifiers that match the type of the variable you are printing to avoid unexpected results or compiler errors.
