C Program to display smallest among three numbers

C Program to display smallest  among three numbers

In this tutorial, we discuss C Program to display smallest  among three numbers

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

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

Find smallest among integer numbers

Program 1

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

int main()
{
    int num1,num2,num3;//variable declaration
    printf("Enter tree numbers\n");
    scanf("%d %d %d",&num1,&num2,&num3);
    //Takse three input num1,num2,num3 from user
    if(num1<num2 && num1<num3){
            //check whether num1 is smaller than num2 and num3
        printf("\n%d 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%d is smallest",num2);//when it is true this statements is displayed
    }
    else{
        printf("\n%d is smallest",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
76
54
32

32 is smallest

Find smallest among float numbers

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

int main()
{
    float num1,num2,num3;//variable declaration
    printf("Enter three numbers\n");
    scanf("%f %f %f",&num1,&num2,&num3);
    //Takse three input num1,num2,num3 from user
    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
    getch();
    return 0;
}

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

Enter three numbers
34.56
23.43
67.54

23.43 is smallest
