C Type Casting: Simple Guide & Examples

In the C language, you can use the cast operator to perform type casting. The general form of the cast operator is:

(type_name) expression

In this case, type_name represents the target type that needs to be converted, while expression represents the expression needing the conversion. The type conversion operator transforms the expression into a value of type_name.

For example, you can use a type-casting operator to convert an integer to a float.

int num = 10;
float f_num = (float) num;

In the above code, convert the integer variable ‘num’ to a floating point number and assign it to the floating point variable ‘f_num’.

It is important to be aware that when performing typecasting, there may be a loss of precision or overflow, so careful usage is necessary.
