Internally, however, they are stored as zero and one. if() Statements The if() statement is used to check for conditions. Just like we use if in normal English, if() in code is used to test for a condition—they test for the value of a boolean (or any int—in this case, a zer...
In instances where the condition yields a false outcome, the code segment enfolded within the secondary set of curly braces (the “else” block) becomes active and is executed. Flowchart of if-else Statement in C: The flowchart of the “if-else” statement helps illustrate its working +--...
In this example, the statement y = x/i; is executed if i is greater than 0. If i is less than or equal to 0, i is assigned to x and f( x ) is assigned to y. Note that the statement forming the if clause ends with a semicolon....

if(!100)//!100为逻辑表达式 printf("expression show!"); for(inti=10; i<10; i++)//for包含3个表达式,分别为i=10 i<10 i++ printf("expression show!"); while(1)//1也是一个表达式 { printf("death loop!"); } 2. 语句 语句指的是当程序运行时执行某个动作的语法结构。它改变变量的值,...
If there is multiline code and you do not use curly braces, then only first statement of the body is considered as if statement body. Be sure, when you have to use curly braces or not? Consider the given example: #include<stdio.h>intmain(){inta=10;intb=-10;intc=0;if(a==10)pri...
When we need to execute a block of statements only when a given condition is true then we use if statement. In the next tutorial, we will learn C if..else, nested if..else and else..if. C - If statement Syntax of if statement: The statements inside the b

The `if` and `switch` statements provide branching logic in C#. You use `if, `else` and `switch` to choose the path your program follows.
In the last tutorial we learned how to use if statement in C. In this guide, we will learn how to use if else, nested if else and else if statements in a C Program. C If else statement Syntax of if else statement: If condition returns true then the state
