The else..if statement is useful when you need to check multiple conditions within the program, nesting of if-else blocks can be avoided using else..if statement. Syntax of else..if statement: if(condition1){//These statements would execute if the condition1 is true}elseif(condition2){//...
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 ...
When using if statements, you will often wish to check multiple different conditions. You must understand the Boolean operators OR, NOT, and AND. The boolean operators function in a similar way to the comparison operators: each returns 0 if evaluates to FALSE or 1 if it evaluates to TRUE. ...
Keep conditions simple: Complex conditions can often be broken down into multiple statements or simplified using logical operators. Use comments wisely: Commenting on the purpose of an If statement can clarify the intention behind complex conditions. Avoid deep nesting: If you find yourself nesting If...

1. if Statement if condition is true, then single statement or multiple statements inside the curly braces executes, otherwise skipped and control is transferred to statement following the if clause conditional expression can be exploited to be any expression, function call, literal constant, string ...
All conditional-compilation directives, such as#ifand#ifdef, must match a closing#endifdirective before the end of file. Otherwise, an error message is generated. When conditional-compilation directives are contained in include files, they must satisfy the same conditions: There must b...
Multiple factors need to be considered for this considerable progress. First and foremost, with the rapid development of our society, increasingly growing enterprises and factories around our city as well as the ways that people travel have led to serious environment pollution, which, as a wake-up...
If conditions always use curly brackets, or single line statements without linebreak: if (err) return -1;. NULL and nullptr are generally just represented as 0. Comments are old-school C-style (pre C99). Text is generally cased with punctuation: /* A comment. */ true and false keywords...
If a conditional statement featuresif,else, and maybe evenelse if, and at least one of the branches contains multiple statements, there should be braces around each branch. The exception is the lastelsewhere braces can be omitted: if(0== found){*curr = zbx_strpool_intern(new);}elseif(0...
