Find the Greatest of the Three Numbers in C
Find the Greatest of Three Numbers in C
Given three integers num1, num2 and num3 as inputs. The objective is to write a code to Find the Greatest of the Three Numbers in C Language. To do so we’ll check the numbers with each other and print the largest of them all.
Example
Input : num1 = 2 num2 = 9 num3 = 4
Output : 9
Find the Greatest of the Three Numbers in C
Given Three integer inputs num1, num2 and num3, the objective is ti write a code to Find the Largest of the Three Numbers in C Language. In this article we will see a C program to Find Greatest of three numbers in C. We will use if else conditions and ternary operator too to find the same. Here are some of the methods to solve the above mentioned problem,
- Method 1: Using if-else Statements 2
- Method 2: Using if-else Statements 2
- Method 3: Using Ternary Operator
We’ll discuss the above mentioned methods in the sections below in depth.
Method 1: Using if-else Statements 1
C Code
Run
#include <stdio.h>
int main ()
{
int num1, num2, num3;
num1=12,num2=17,num3=19;
//checking if num1 is greatest
if (num1 >= num2 && num1 >= num3)
printf("%d is the greatest", num1);
//checking if num2 is greatest
else if(num2 >= num1 && num2 >= num3)
printf("%d is the greatest", num2);
//checking if num2 is greatest
else if(num3 >= num1 && num3 >= num2)
printf("%d is the greatest", num3);
return 0;
}
Output
19 is the greatest
Method 2: Using if-else Statements 2
C Code
Run
#include <stdio.h>
int main ()
{
int num1, num2, num3;
num1=13,num2=45,num3=27;
//comparing num1 with other numbers
if ((num1 >= num2) && (num1 >= num3))
printf("%d is the greatest", num1);
//comparing num2 with other numbers
else if ((num2 >= num1) && (num2 >= num3))
printf("%d is the greatest", num2);
// num3 has to be greatest then if not above
else
printf("%d is the greatest", num3);
return 0;
}
Output
45 is the greatest
Method 3: Using Ternary Operator
In this method we use the knowledge of Ternary Operators in C
Ternary Operator Syntax
( Condition ) ? ( if True : Action ) : ( if False : Action )
C Code
Run
#include <stdio.h>
int main ()
{
int num1, num2, num3;
num1=12,num2=98,num3=84;
int temp, result;
// find the largest b/w num1 and num2 & store in temp
temp = num1>num2 ? num1:num2;
// find the largest b/w temp and num3 & finally printing it
result = temp>num3 ? temp:num3;
printf(" %d is the largest", result);
return 0;
}
Output
98 is the largest

#include
void main()
{
int a,b,c;
printf(“enter a,b,c:”);
scanf(“%d%d%d”,&a,&b,&c);
(a>b&&a>c)?printf(“%d”,a):b>c?printf(“%d”,b):printf(“%d”,c);
}
is this code right && is it good practice?
#include
int main(){
int n1,n2,n3;
scanf(“%d %d %d”,&n1,&n2,&n3);
printf(“%d \n”,((n1>n2?n1:n2)>(n2>n3?n2:n3))?(n1>n2?n1:n2):(n2>n3?n2:n3));
return 0;
