This example shows how you can use if..else to "open a door" if the user enters the correct code:Example int doorCode = 1337;if (doorCode == 1337) { printf("Correct code.\nThe door is now open.");} else { printf("Wrong code.\nThe door remains closed.");} Try it Yourself...
Example: #include <stdio.h> int main() { int num = 10; if (num > 5) { printf("The number is greater than 5.\n"); } else { printf("The number is not greater than 5.\n"); } return 0; } In this example, the condition num > 5 is evaluated. Since the value of num is...
/* statement(s) will execute if the boolean expression is false */ } 如果布尔表达式的计算结果为true,则执行if block,否则执行else block。 C编程语言将任何non-zero和non-null值假定为true,如果它zero或null,则将其假定为false值。 流程图 (Flow Diagram) 例子(Example) #include <stdio.h> int main ...

C/C++ if else statement with ExamplesC/C++ 中的决策制定 有助于编写决策驱动语句和根据特定条件执行一组特定的代码。if 语句单独告诉我们,如果条件为真,...
In computer programming, we use the if...else statement to run one block of code under certain conditions and another block of code under different conditions. For example, assigning grades (A, B, C) based on marks obtained by a student. if the percentage is above 90, assign grade A ...

Code Example: #include <iostream> using namespace std; int main() { int marks = 80; if (marks >= 90) { cout << "Grade A"; } else if (marks >= 80) { cout << "Grade B"; } else if (marks >= 60) { cout << "Grade C"; } else if (marks >= 40) { cout << "Grade...
Lets take the same example that we have seen above while discussing nested if..else. We will rewrite the same program using else..if statements. #include<stdio.h>intmain(){intvar1,var2;printf("Input the value of var1:");scanf("%d",&var1);printf("Input the value of var2:");scan...
In this example, since number is greater than 0, the condition evaluates to true, and the message “The number is positive.” is printed to the screen. Understanding If-Else Statement The if-else statement extends the functionality of the if statement by allowing an alternative set of instruct...
