The role of / and % in c++

The / and % operators in C are used for division and remainder operations respectively. Division (/) returns the quotient, Remainder (%) returns the remainder in division.

The functions of / and % in C

/ and % in C are two operators, respectively Represents division and remainder.

Division (/)

The division operator (/) performs arithmetic division on two operands and returns the quotient. For example:

<code class="cpp">int x = 10 / 5; // 结果为 2</code>

When the operand is a floating point number, the division operator returns a floating point number result. For example:

<code class="cpp">float y = 10.0 / 5.0; // 结果为 2.0</code>

Remainder (%)

Remainder operator (%) performs a remainder operation on two operands and returns the remainder during division remainder. For example:

<code class="cpp">int z = 10 % 5; // 结果为 0</code>

The sign of the remainder is the same as the sign of the dividend. If the dividend is positive, the remainder is positive; if the dividend is negative, the remainder is negative. For example:

<code class="cpp">int a = -10 % 5; // 结果为 -10</code>

It should be noted that the remainder operation has no meaning on floating point operands, and can only be performed on integer operands.
