What does 2f represent in C language?

In C language, 2f represents a floating-point literal , whose value is 2.0. The f suffix indicates that the number is a floating point number, not an integer.

Detailed explanation:

• In C language, numeric literals can be integers or floating point numbers.
• Integer literals do not take any suffix, while floating point literals are represented by f or F suffix.
• Floating point numbers represent numbers with a decimal part, while integers do not contain a decimal part.
• 2f represents the floating point number 2.0, in which the decimal part is 0.
• Floating point literals can be used to represent very large or very small numbers that cannot be represented by integer literals.

Example:

The following code snippet demonstrates how to use 2f to represent a floating point number:

<code class="c">int main() {
  float x = 2.0f;
  printf("x = %f\n", x);
  return 0;
}</code>

Output:

<code>x = 2.000000</code>
