What does uint mean in C language

Uint in C is an unsigned integer type used to represent positive integers and 0s. Features include: 32 or 64-bit memory usage, only positive integer operations can be performed, and cannot be mixed with signed integers. Advantages include avoiding unexpected behavior caused by negative values ​​and improving code efficiency.

Uint in C language

uint is a keyword in C language that represents unsigned integers.

meaning:

uint is an unsigned integer type, which means it cannot represent a negative value.

Features:

• Variables of type uint can only store positive integers and 0s.
• Variables of type uint occupy 32-bit or 64-bit memory, depending on the compiler architecture.
• Variables of type uint cannot be mixed with signed integer types (such as int).

usage:

The uint variable is declared as follows:

 <code class="c">uint my_uint;</code>

The uint variable can store positive integers and 0s, or perform arithmetic operations:

 <code class="c">my_uint = 10; my_uint = 5; // my_uint 现在等于15</code>

Advantages:

There are some advantages to using the uint type:

• Avoid unexpected behavior caused by negative values.
• For applications that only need to deal with positive integers, code efficiency can be improved.

Notice:

• Overflow: A variable of type uint has a maximum value. If it exceeds this value, it will cause overflow and produce undefined behavior.
• Conversion: Variables of type uint cannot be implicitly converted to signed integer types, and explicit conversion is required (for example (int)my_uint).
