How to perform char type conversion in C language

In C language, the char type represents a single-byte character. Type conversion refers to converting data of one type to another. The char type can be type-converted using cast or automatic type-converter.

Force type conversion

The cast uses the type name followed by parentheses that contain the expression to be converted. For example:

 <code class="c">int a = 65; char b = (char)a;</code>
Copy after login

In this example, a is a value of type int , and b is a value of type char . Cast converts the value of a to char type, thus converting the number 65 to the character 'A'.

Automatic type conversion

Automatic type conversion occurs when the compiler automatically converts one type of data to another. For example:

 <code class="c">int a = 65; char b = a;</code>
Copy after login

In this example, the compiler automatically converts int type value of a to char type, because char variable b can accommodate int type value when assigned.

Notes on type conversion

When performing type conversion, the following precautions need to be considered:

  • The target type must be able to accommodate the value of the source type.
  • Casting may result in data loss because the target type may not accurately represent the value of the source type.
  • Automatic type conversion is usually safe, but attention should be paid to the differences in representation range and precision between different types.
