C Output(Print Text)
C Data Types: A Comprehensive Guide In C programming, data types define the kind of information a variable can hold and the operations that can be performed on it. Understanding different data types is crucial for writing efficient and reliable C programs.
Here's a breakdown of various aspects of C data types:
To output values or print text in C, you can use the printf() function:
Example
Example
// Create variables
int myNum = 5; // Integer (whole number)
float myFloatNum = 5.99; // Floating point number
char myLetter = 'D'; // Character
// Print variables
printf("%d\n", myNum);
printf("%f\n", myFloatNum);
printf("%c\n", myLetter);
int myNum = 5; // Integer (whole number)
float myFloatNum = 5.99; // Floating point number
char myLetter = 'D'; // Character
// Print variables
printf("%d\n", myNum);
printf("%f\n", myFloatNum);
printf("%c\n", myLetter);
Basic Data Types
The data type specifies the size and type of information the variable will store.
In this tutorial, we will focus on the most basic ones:
| Data Type | Size | Description | Example |
|---|---|---|---|
int |
2 or 4 bytes | the int data type is essential for working with integers - whole numbers without decimal points. | 1 |
float |
4 bytes | float is a data type used to represent single-precision floating-point numbers. Sufficient for storing 6-7 decimal digits | 1.99 |
double |
8 bytes | Stores fractional numbers, containing one or more decimals. Sufficient for storing 15 decimal digits | 1.99 |
char |
1 byte | he char data type in C is used to represent a single character, or ASCII values | 'A' |
