1)新建 SourceCodeModel.cs 用作记录代码源码地址源码类型等。 namespaceWPFDevelopers.Samples.Controls { publicclassSourceCodeModel { publicCodeType CodeType {get;set; } publicstringHaader {get;set; } publicstringCodeSource {get;set; } } publicenumCodeType { Xaml, CSharp, } } 2)新建 CodeViewer...
If the condition statements associated with else if block evaluated to return a TRUE boolean value, R process the code available inside the else if block. However, if the condition of else it returns a FALSE boolean value, R ignores the code and checks for next else if statement. If it f...
This sample code shows several if statements in use, both with and without else: C++ Copy // if_else_statement.cpp #include <iostream> using namespace std; int main() { int x = 10; if (x < 11) { cout << "x < 11 is true!\n"; // executed } else { cout << "x < 11...
Example: Python if…else Statement number = int(input('Enter a number: '))ifnumber >0:print('Positive number')else:print('Not a positive number')print('This statement always executes') Run Code Sample Output 1 Enter a number: 10 Positive number This statement always executes If user enter...
In the sample C++ program- We first declare an integer variable marks inside the main() function and initialize it with the value of 28. As mentioned in code comments, we then employ an if-else statement to check if the student has passed or failed. We check the condition to see if th...
