Go Compiler: Addressing the "Declared but not used" Error

In the Go programming language, encountering the error "declared but not used" indicates that a variable has been declared but not utilized in the program. To resolve this issue, it is crucial to modify your code to include usage of the declared variable.

Consider the following code snippet:

// Using var keyword
var partial string

for i, request := range requestVec {
    if i == (len(requestVec)-1) && !strings.Contains(request, "\r\n\r\n") {
        partial = request
        break
    }
}

In this example, the variable partial is declared using the var keyword but is only assigned a value within the loop. To rectify the issue, you can introduce additional code that reads the value of partial. For instance:

var partial string

for i, request := range requestVec {
    if i == (len(requestVec)-1) && !strings.Contains(request, "\r\n\r\n") {
        partial = request
        break
    }
}

fmt.Println(partial) // We are now using `partial`

By incorporating the fmt.Println() statement, we effectively utilize the partial variable and resolve the "declared but not used" error.
