C program to Find Largest of three numbers
In this article, we will discuss the concept of C program to Find Largest of three numbers
In this post, we are going to learn how to write a program to find largest number out of three numbers using different methods in C program.
Code to find largest numbers
Code to find largest numbers using if statements
In this code, we will find largest number out of three numbers using if statements in C language
Program 1
#include <stdio.h>
#include <stdlib.h>
//int biggestNum(int a, int b,int c);
int main()
{
int num1,num2,num3; //declare the variables
printf("Please Enter the first number: ");
scanf("%d",&num1);//get input from user for num1
printf("Please Enter the second number: ");
scanf("%d",&num2);//get input from user for num2
printf("Please Enter the third number: ");
scanf("%d",&num3);//get input from user for num3
if(num1>=num2 && num1>=num3){
printf("\n The largest number is: %d",num1);
//Checking the num1 is largest
}
if(num2>=num1 && num2>=num3){
printf("\n The largest number is: %d ",num2);
//Checking the num2 is largest
}
if(num3>=num1 && num3>=num2){
printf("\n The largest number is:%d ",num3);
//Checking the num3 is largest
}
getch();
return 0;
}
When the above code is executed , it produces the following result
Please Enter the first number: 365 Please Enter the second number: 987 Please Enter the third number: 654 Largest number is: 987
Code to find largest numbers using if-else if statements
In this code, we will find largest number out of three numbers using if else if statements in C language
Program 2
#include <stdio.h>
#include <stdlib.h>
int main()
{
int num1, num2,num3; //variables declaration
printf("Enter the first number: ");
//Ask input from the user
scanf("%d",&num1);//Reading the input in num1
printf("Enter the second number: ");
scanf("%d",&num2);//Reading the input in num2
printf("Enter the third number: ");
scanf("%d",&num3);//REading the input in num3
if(num1>=num2 && num1>=num3){
printf("\nLargest number is: %d\n",num1);
}//num1 compare num 2 and num 3
else if(num2>=num1 && num2>=num3){
printf("\nLargest number is: %d\n",num2);
}//num2 compare num1 and num3
else{
printf("\nLargest number is: %d\n",num3);
}
getch();
return 0;
}
When the above code is executed , it produces the following result
Please Enter the first number: 6785 Please Enter the second number: 9834 Please Enter the third number: 1233 Largest number is: 9834
Code to find largest numbers using nested if statements
In this code, we will find largest number out of three numbers using Nested if statements in C language
Program 3
#include <stdio.h>
#include <stdlib.h>
//int biggestNum(int a, int b,int c);
int main()
{
int num1,num2,num3; //declare the variables
printf("Please Enter the first number: ");
scanf("%d",&num1);//get input from user for num1
printf("Please Enter the second number: ");
scanf("%d",&num2);//get input from user for num2
printf("Please Enter the third number: ");
scanf("%d",&num3);//get input from user for num3
if(num1>=num2){//checking num1 and num2
if(num1>=num3){//checking num1 and num3
printf("\nLargest number is: %d\n",num1);
}
else{
printf("\nLargest number is: %d\n",num3);
}
}
else{
if(num2>=num3){//checking num2 and num1
printf("\nLargest number is: %d\n",num2);
}
else{
printf("\nLargest number is: %d\n",num3);
}
}
getch();
return 0;
}
When the above code is executed , it produces the following result
Please Enter the first number: 786 Please Enter the second number: 432 Please Enter the third number: 987 Largest number is: 987
Code to find largest numbers using function
In this code, we will find largest number out of three numbers using function in C language
Program 4
#include <stdio.h>
#include <stdlib.h>
biggestNumber(int,int,int);//function prototype
int main()
{
int a,b,c;
printf("Enter the three numbers\n");
scanf("%d%d%d",&a,&b,&c);
int result=biggestNumber(a,b,c);//Calling the function
printf("Biggest number is: %d\n",result);
//display the result
getch();
return 0;
}
int biggestNumber(int a,int b,int c){//function definition
if(a>b)
{
if(a>c)
return a;
else
return c;
}
else
{
if(b>c)
return b;
else
return c;
}
}
When the above code is executed , it produces the following result
Enter the three numbers 765 123 567 Biggest number is: 765
Code to find largest numbers using ternary operator
In this code, we will find largest number out of three numbers using ternary operator in C language
Program 5
#include <stdio.h>
#include <stdlib.h>
//int biggestNum(int a, int b,int c);
int main()
{
int num1,num2,num3; //declare the variables
printf("Please Enter three numbers: ");
//Ask input from the user
scanf("%d %d %d",&num1,&num2,&num3);
//get input from user and store the variables
int result=num3>(num1>num2?num1:num2)?num3:((num1>num2)? num1:num2);
printf("Largwst number is: %d",result);
getch();
return 0;
}
When the above code is executed , it produces the following result
Please Enter three numbers: 567 432 879 Largest number is: 879
Program 6
#include <stdio.h>
#include <stdlib.h>
//int biggestNum(int a, int b,int c);
int main()
{
int num1,num2,num3; //declare the variables
printf("Enter three numbers: ");
//Ask input from the user
scanf("%d %d %d",&num1,&num2,&num3);
//get input from user and store the variables
int temp=(num1>num2)? num1:num2;
int largest= num3>temp?num3:temp;
printf("Largest number is: %d",largest);
getch();
return 0;
}
When the above code is executed , it produces the following result
Please Enter three numbers: 1004 2045 5460 Largest number is: 5460
Code to find largest numbers using Array in C language
In this code, we will find largest number out of three numbers using Array in C language
Program 7
#include <stdio.h>
#include <stdlib.h>
int main()
{
int arr[10], size,i;
printf("Enter the number of elements in an array\n");
scanf("%d",&size);//takes input from user for array length
printf("Enter %d integers \n",size);
for(i=0; i<size; i++){
printf("Enter the element %d: ",(i+1));
scanf("%d",&arr[i]);//takes input from user for array
}
int max=arr[0];
for(i=0; i<size; i++){
if(max<arr[i]){
max=arr[i];
}
}
printf("\nThe largest value is:%d ",max);
getch();
return 0;
}
Enter the number of elements in an array 3 Enter 3 integers Enter the element 1: 45 Enter the element 1: 56 Enter the element 1: 67 The largest value is : 67
