Answer :
If we analyze the lines of codes, the execution of “for” statement may land up in error. The first statement will receive the input from the user. Next a variable “grades” is declared as double. Next and empty line will get printed using “Println()” function. Next a for loop runs.
Usually for loop should contain initialization, test condition and the increment value. Here, the initialization is done, but the condition is not provided properly and the syntax is not followed which may yield an error.
