Output in C

Outputting an Integer

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Integer output
    int num = 10;  // Integer variable

    // Print the integer
    printf("The integer is: %d\n", num);

    return 0;
}
        

Explanation: This program assigns the integer value 10 to the variable num and prints it using printf.

Outputting a Floating-Point Number

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Floating-point output
    float fnum = 3.14;  // Floating-point variable

    // Print the floating-point number
    printf("The floating-point number is: %.2f\n", fnum);

    return 0;
}
        

Explanation: This program assigns the floating-point value 3.14 to the variable fnum and prints it using printf with 2 decimal places.

Outputting a Double

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Double output
    double dnum = 3.1415926535;  // Double variable

    // Print the double
    printf("The double is: %.10f\n", dnum);

    return 0;
}
        

Explanation: This program assigns the double value 3.1415926535 to the variable dnum and prints it using printf with 10 decimal places.

Outputting a Character

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Character output
    char ch = 'A';  // Character variable

    // Print the character
    printf("The character is: %c\n", ch);

    return 0;
}
        

Explanation: This program assigns the character 'A' to the variable ch and prints it using printf.

Outputting a String

#include<stdio.h>  // Include the standard input-output library

int main() {
    // String output
    char str[] = "Hello, World!";  // String variable

    // Print the string
    printf("The string is: %s\n", str);

    return 0;
}
        

Explanation: This program assigns the string "Hello, World!" to the variable str and prints it using printf.

Formatted Output

#include<stdio.h>  // Include the standard input-output library

int main() {
    // Formatted output
    int i = 10;
    float f = 3.14;
    char c = 'A';
    char str[] = "Hello";

    // Print formatted output
    printf("Integer: %d, Float: %.2f, Char: %c, String: %s\n", i, f, c, str);

    return 0;
}
        

Explanation: This program demonstrates formatted output by printing an integer, a floating-point number, a character, and a string all in one printf statement.

Explanation:

This HTML document contains several simple C programs with syntax highlighting using CSS. Each section demonstrates a different method of output in C:

• Outputting an Integer: Uses printf to print an integer.
• Outputting a Floating-Point Number: Uses printf to print a floating-point number with 2 decimal places.
• Outputting a Double: Uses printf to print a double with 10 decimal places.
• Outputting a Character: Uses printf to print a character.
• Outputting a String: Uses printf to print a string.
• Formatted Output: Demonstrates how to print multiple variables of different types in a single printf statement.
