What symbols are used in c++?

The assignment operator (=) in C is used to copy a value to another variable. In addition, C provides other assignment operators for combining assignment operations, such as = (additive assignment), -= (subtractive assignment), and *= (multiplicative assignment).

Assignment in c

In C, the assignment operator is used to copy the value of one variable to another in a variable. The assignment operator is =.

Basic syntax

<code class="cpp">变量 = 值;</code>

For example:

<code class="cpp">int x = 10;</code>

This will change the variablex## The value of # is set to 10.

Assigned to the reference

If the variable is a reference, the assignment operator will modify the referenced target variable value. For example:

<code class="cpp">int& y = x;
y = 20;</code>

This changes the value of variable

x to 20.

Other assignment operators

In addition to the basic assignment operators, C also has several other assignment operators for combined assignment operations:

• = (Additional assignment)
• -= (subtraction assignment)
• *= (multiplication assignment)
• /= (division assignment)
• %= (modulo assignment)
• <<= (left shift assignment)
• > ;>= (right shift assignment)
• &= (bitwise AND assignment)
• |= (bitwise OR Assignment)
• ^= (Bitwise XOR assignment)

For example:

<code class="cpp">x += 5; // 等同于 x = x + 5</code>
