Final answer:
In C, arithmetic type/expression casting is handled using type conversion. Type conversion allows you to change the data type of an expression or variable. When two operands of different types are involved in an arithmetic operation, the operand with the lower precision is implicitly converted to the type of the operand with higher precision.
Step-by-step explanation:
In C, arithmetic type/expression casting is handled using type conversion. Type conversion allows you to change the data type of an expression or variable. When two operands of different types are involved in an arithmetic operation, the operand with the lower precision is implicitly converted to the type of the operand with higher precision. This ensures that the operation is performed correctly and the result is accurate.
For example, if you have an expression like intResult = intOperand1 / floatOperand2;, the float operand will be converted to an int type before performing the division operation. This is because an int has higher precision than a float.
It's important to note that type conversion can result in loss of data if the precision is reduced. In such cases, it's recommended to use explicit casting to ensure the desired result.
