nested-if

问题 My homework task is to create a program that accepts a numeric input between 0-100 and returns a letter and +/- if appropriate. We are to accomplish this using nested if statements. I attempted to create an outer if statement that would return a letter grade followed by nested if statements that would return the +/- part. The output I receive varies from 6543 to 00. I have copied my code below. Could anyone point me in the right direction? I feel like this is a bit of a mess. import java.util

问题 Alright, so I know that if a particular conditional branch has a condition that takes time to compute (memory access, for instance), the CPU assumes a condition result and speculatively executes along that path. However, what would happen if, along that path, yet another slow conditional branch pops up (assuming, of course, that the first condition hasn't been resolved yet and the CPU can't just commit the changes)? Does the CPU just speculate inside the speculation? What happens if the last

问题 This is my script: echo "Name" read name if [ "$name" == "abcd" ]; then echo "Password" read password if [ "$password == "pwd" ]; then echo "Hello" else echo "Wrong password" fi else echo "wrong username" fi And this is the output I get when I run it: sh hello.sh Name abcd hello.sh: line 14: unexpected EOF while looking for matching `"' hello.sh: line 16: syntax error: unexpected end of file Any idea whats wrong here? This could be a very silly one, but i wasted almost an hour on it. 回答1: if

问题 I want to show a message box when a specific cell has a particular value in it. I have done this with the following code; If Range("P8") = "Y" Then MsgBox "Message here" End If This is within the Worksheet_Change sub so shows the message box everytime another cell value changes. I have tried to get around this by adding a boolean variable, set to true when the messagebox has been shown the first time; If Range("P8") = "Y" Then If messageshown = False Then messageshown = True MsgBox "Message

问题 From the point of view of optimizing the code run time, is there a thumb rule for where to use "nested if" statement and when to use "switch case" statements ? 回答1: I doubt you will ever find a real-life application where the difference between a nested if and a switch case is even worth measuring. Disk access, web access, etc. take many many orders of magnitude more time. Choose what is easiest to read and debug. Also see What is the difference between IF-ELSE and SWITCH? (possible duplicate

问题 I want to display records in MS SSRs based on multiple IFFs Condition. Any idea? Please help me! My table is "customers" and columns are "cust1", "cust2", "cust3", "cust4" if(cust1.value!=null) { display cust1; if(cust2.value!=null) { display cust1+","+cust2; } if(cust3.value!=null) { diplay cust1+","+cust2+"and+"+cust3 } if(cust4.value!=null) { diplay cust1+","+cust2+","+cust3+"and"+cust4; } }else diplay cust1; I just wrote C# syntax for understand logic. I want to display like result Ex:
