C Type Conversion Guide

In C language, variables can be converted from one type to another through either explicit or implicit type conversion.

1. Forced type conversion: Use the forced type conversion operator to convert a variable to the target type. The syntax is as follows:
2. Target-type variable
3. For example, converting a variable of integer type to float type.
4. Convert the integer variable num to a floating point number and store it in the float variable floatNum.
5. Implicit type conversion: When variables of different types are used in an expression, the compiler will automatically convert the types. Implicit type conversion usually follows certain rules, such as converting from lower precision types to higher precision types, and from integer types to floating-point types. For example:
6. int num1 is equal to 10;
   float num2 is equal to 2.5;
   float result is equal to the sum of num1 and num2. // num1 will automatically be converted to a floating point type before the operation.

It is important to note that when performing data type conversion, data loss or data accuracy issues may occur, so careful consideration should be taken before performing any type of conversion.
