Program for find middle number out of three in C

Program for find middle numbers out of three in C

In this article, we will discuss the concept of Program for find middle numbers out of three numbers in C

In this post, we are going to learn how to write a program to find middle number out of three numbers using different methods in C program.

Code to find middle numbers

Code to find middle numbers  using if statements

In this code, we will find middle number out of three numbers using if statements in C language

Program 1

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

int main()
{
    int num1,num2,num3;//variable declaration
    printf("Enter three numbers\n");
//Ask input from the user
    scanf("%d %d %d",&num1,&num2,&num3);
//store the entered value on the variables
    //checking num1 is a middle number or not
    if(num2>num1 && num1>num3 || num3>num1&& num1>num2){
        printf("\n %d is a middle number",num1);
    }

    //checking num2 is a middle number or not
    if(num1>num2&& num2>num3 || num3>num2 && num2>num1){
        printf("\n %d is a middle number",num2);
    }

    //checking num3 is a middle number or not
    if(num1>num3 && num3>num2 || num2>num3 && num3>num1){
        printf("\n %d is a middle number",num3);
    }
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Enter the three numbers
345
125
566
345 is a middle number

 

Code to find middle numbers  using Nested if statements

In this code, we will find middle number out of three numbers using Nested if in C language

Program 2

#include <stdio.h>
#include <stdlib.h>
int middleNumber(int,int,int);
int main(){
    int num1,num2,num3,middle;//Variable declaration
    printf("Enter the three numbers\n");
//Ask input from the user
    scanf("%d %d %d",&num1,&num2,&num3);//takes input from user


    if(num1>num2){
        if(num2>num3){
        middle=num2;
    }
    else if(num3>num1){
        middle=num1;
    }
    else{
        middle=num3;
    }
    }

    else{

        if(num2<num3){
        middle=num2;
    }
    else if(num3<num1){
        middle=num1;
    }
    else{
        middle=num3;
    }


}
 printf("Middle number is %d",middle);
//Display result on the screen
getch();
    return 0;

}

When the above code is executed, it produces the following result

Enter the three numbers:
5678
1234
3456
Middle number is 3456

 

 

Code to find middle numbers  using function

In this code, we will find middle number out of three numbers using function in C language

Program 3

#include <stdio.h>
#include <stdlib.h>
int middleNumber(int,int,int);//function prototype
int main()
{
    int num1,num2,num3;//Variable declaration
    printf("Enter the three numbers\n");
    scanf("%d %d %d",&num1,&num2,&num3);//takes input from user
    printf("Middle number is %d",middleNumber(num1,num2,num3));
//Call the function and display result on the screen
    getch();
    return 0;
}

int middleNumber(int num1,int num2,int num3){//function definition
    int middle=0;

    if(num1>num2){
        if(num2>num3){
        middle=num2;
    }
    else if(num3>num1){
        middle=num1;
    }
    else{
        middle=num3;
    }
    }

    else{

        if(num2<num3){
        middle=num2;
    }
    else if(num3<num1){
        middle=num1;
    }
    else{
        middle=num3;
    }

}

}

When the above code is executed, it produces the following result

Enter the three numbers
678
123
456
Middle number is 456
