C - Building a logical comparison inside if statement

Introduction

It's possible to load two or more comparisons into a single if statement.

The results of the comparisons are compared by using a logical operator.

When the result of the entire thing is true, the if condition is considered true.

Demo

#include <stdio.h> 

int main() // ww w  . j  a  va  2s  . c  om
{ 
      int coordinate; 

      printf("Input target coordinate: "); 
      scanf("%d",&coordinate); 
      if( coordinate >= -5 && coordinate <= 5 ) 
      { 
          puts("Close enough!"); 
      } 
      else 
      { 
          puts("Target is out of range!"); 
      } 
      return(0); 
}

Result

Two comparisons are made by the if statement condition.

Logical operators

The C language logical comparison operators are shown in the following table.

These operators can be used in an if comparison when two or more conditions must be met.

Operator	Name	True When
&&	and	Both comparisons are true
||	or	Either comparison is true
!	not	The item is false
