What is / used for in C language?

Has lower precedence than the multiplication operator and produces an error or infinity when either the dividend or the divisor is 0, or NaN when both are 0.

Use of / in C language

In C language, the division operator / is used to calculate two The quotient of the expression.

Usage:

##result = expression1 / expression2;

• result is the result variable
• expression1 is the dividend
• expression2 is the divisor

Return type:

Priority:

Special cases:

• The dividend is 0: When the dividend is 0, the division operation will generate an error.
• The divisor is 0: When the divisor is 0, the division operation will produce an infinite value. However, if both the dividend and the divisor are 0, the result is NaN (not a number).

Example:

<code class="c">int num1 = 10;
int num2 = 5;
float result = num1 / num2;

printf("result = %.2f\n", result); // 打印 result 的浮点数表示</code>

<code>result = 2.00</code>
