Answer:
Explanation:
In most programming languages, the result of an expression involving a combination of different data types will be determined by a set of rules known as type coercion or type promotion. These rules define how the data types are implicitly converted to a common data type to perform the operation.
Let's break down the expression a + b * c - d based on the given data types:
a and b are both of type int.
c and d are both of type float.
In this expression, the multiplication b * c will likely result in a float because when you multiply an int with a float, the result is typically promoted to a float. This is an example of implicit type conversion or type promotion.
So, the expression a + b * c - d will have a float result because of the presence of floating-point values in the expression (c and d).
In some programming languages, you may explicitly specify the data type of the result using casting or type conversion. However, without explicit type casting, the result will generally follow the rules of type promotion and become a float.
