How Do I Correctly Evaluate Function Return Values in Go's Conditional Statements?

Function Evaluation and Value Assignments in Go

In Go, when evaluating functions within conditional statements, it's essential to ensure proper syntax and return values.

When calling sumThis(1, 2) and sumThis(3, 4) in the "if" statement, Go interprets them as expressions used as values, not function calls. To resolve this error, it's necessary to explicitly declare a return value for the sumThis function.

The correct way to write the function is:

func sumThis(a, b int) int {
        return a + b
}

By specifying the return data type "int," Go knows that the function is intended to return an integer value. After this modification, the conditional statement will function as expected. Remember, when calling functions in Go, it's essential to define and return the appropriate data types to ensure proper evaluation in conditional statements and avoid any compilation errors.
