C Program to largest and smallest among three numbers

C Program to smallest and largest among three numbers

In this tutorial, we discuss C Program to the smallest and largest among three numbers

In this program, we will discuss a simple concept of the program to find the smallest and largest among three numbers in the C programming language.

In this topic, we learn how to find the smallest and largest number from given three numbers using if statements.

Find smallest and largest among three integer numbers

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num1,num2,num3;//variable declaration
    printf("Enter three numbers\n");
    scanf("%d %d %d",&num1,&num2,&num3);
    //Takse three input num1,num2,num3 from user

//check smallest
    if(num1<num2 && num1<num3){
            //check whether num1 is smallest than num2 and num3
        printf("\n%d is the smallest",num1);
    }//if it is truen this statement is displayed
    else if(num2<num3){
        //when it is false then check num2 or num 3 to small
        printf("\n%d is the smallest",num2);//when it is true this statements is displayed
    }
    else{
        printf("\n%d is the smallest",num3);
    }//all statements are false this statement is displayed
//check largest
    if(num1>num2 && num1>num3){//check largest
            //check whether num1 is largest than num2 and num3
        printf("\n%d is largest",num1);
    }//if it is true this statement is displayed
    else if(num2>num3){
        //when it is false then check num2 or num 3 to large
        printf("\n%d is largest",num2);//when it is true this statements is displayed
    }
    else{
        printf("\n%d is largest",num3);
    }//all conditions are false this statement is displayed
    getch();
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter three numbers
45
23
67

23 is the smallest
67 is largest

Find smallest and largest among three float numbers

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    float num1,num2,num3;//variable declaration
    printf("Enter tree numbers\n");
    scanf("%f %f %f",&num1,&num2,&num3);
    //Takse three input num1,num2,num3 from user

//check smallest
    if(num1<num2 && num1<num3){
            //check whether num1 is smaller than num2 and num3
        printf("\n%.2f is smallest",num1);
    }//if it is truen this statement is displayed
    else if(num2<num3){
        //when it is false then check num2 or num 3 small
        printf("\n%.2f is smallest",num2);//when it is true this statements is displayed
    }
    else{
        printf("\n%.2f is smallest",num3);
    }//all statements are false this statement is displayed
//check largest
    if(num1>num2 && num1>num3){
            //check whether num1 is largest than num2 and num3
        printf("\n%.2f is largest",num1);
    }//if it is true this statement is displayed
    else if(num2>num3){
        //when it is false then check num2 or num3 large
        printf("\n%.2f is largest",num2);//when it is true this statements is displayed
    }
    else{
        printf("\n%.2f is largest",num3);
    }//all statements are false this statement is displayed
    getch();
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter three numbers
34.56
12.34
67.5

12.34 is smallest
67.50 is largest
