How to express 2 to the nth power in C language

In C language, you can use the left shift operator (<<) to calculate 2 raised to the nth power. The syntax is: x << n, where x is a number and n is a movement. number of digits (equivalent to a power of 2). For example, 2 << 5 raises 2 to the 5th power, resulting in 32.

The expression of 2 to the nth power in C language

In C language, you can use left shift operator (<<) to calculate 2 raised to the nth power. The function of the left shift operator is to move the number on the left to the left by the specified number of digits, which is equivalent to multiplying by the specified power of 2.

Syntax:

<code>x << n</code>

Where:

• x is the number to be calculated to the nth power of 2
• n is the number of digits to be moved, which is the power of 2

Example:

Calculate 2 5th power:

<code class="c">int result = 2 << 5;</code>

The above code moves 2 to the left by 5 places and gets the result 32, which is 2 raised to the 5th power.

Note:

It should be noted that this method can only be used to calculate the power of 2 of non-negative integers. If n is negative, the behavior of this operator is undefined.
