Example 1: if statement // Program to display a number if it is negative#include<stdio.h>intmain(){intnumber;printf("Enter an integer: ");scanf("%d", &number);// true if number is less than 0if(number <0) {printf("You entered %d.\n", number); }printf("The if statement is ...
C/C++ if 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。C/C++ if 语句是最简单的决策语句。它用于根据某种条件来决定是否执行某个语句或语句块。语法:if(condition) { // Statements to execute if // condition is true }if 语句的工作控制...
The following are examples of theifstatement: C if( i >0) y = x / i;else{ x = i; y = f( x ); } In this example, the statementy = x/i;is executed ifiis greater than 0. Ifiis less than or equal to 0,iis assigned tox, andf( x )is assigned toy. The statement forming...
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 learnC if..else, nested if..else and else..if. C– If statement Syntax of if statement: The statements inside the body of “if” only execute ...
Working of if-else Statement in C Let’s explore how the “if-else” statement works in C: if-else Syntax in C: The basic syntax of the “if-else” statement is as follows: if (condition) { // Code block executed if the condition is true } else { // Code block executed if the...
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
The above two code examples emphasize the fact that when there are more than one statements in the if or else else, they must be put in curly brackets.To be safe, it is always better to use curly brackets even for a single statement. In fact, it improves the readability of the code....
If the condition is true (non-zero), the block of code inside the curly braces is executed. If the condition is false (zero), the block of code is skipped. Simple Example Illustrating If Statement Consider a program that checks if a number is positive: #include <stdio.h> int main() ...
if ( TRUE ) { /* between the braces is the body of the if statement */ Execute all statements inside the body }I recommend always putting braces following if statements. If you do this, you never have to remember to put them in when you want more than one statement to be executed,...
The statement(s) under the ‘else’ condition is returned. The statement(s) under the ‘if’ condition is ignored from execution. For example: Examples Let’s take an example of a Boolean expression with the help of actual coding in C: If the condition is met (true) as per the given...
