Program to find the largest number using if statement

#include <stdio.h>
	int main()
	{
	double n1, n2, n3;
	printf("Enter three numbers: ");
	scanf("%lf %lf %lf", &n1, &n2, &n3);
	if( n1>=n2 && n1>=n3 )
	printf("%.2f is the largest number.", n1);
	if( n2>=n1 && n2>=n3 )
	printf("%.2f is the largest number.", n2);
	if( n3>=n1 && n3>=n2 )
	printf("%.2f is the largest number.", n3);
	return 0;
	}

Program to find the largest number using if-else statement

#include <stdio.h>
	int main()
	{
	double n1, n2, n3;
	printf("Enter three numbers: ");
	scanf("%lf %lf %lf", &n1, &n2, &n3);
	if (n1>=n2)
	{
	if(n1>=n3)
	printf("%.2lf is the largest number.", n1);
	else
	printf("%.2lf is the largest number.", n3);
	}
	else
	{
	if(n2>=n3)
	printf("%.2lf is the largest number.", n2);
	else
	printf("%.2lf is the largest number.",n3);
	}
	return 0;
	}

Program to find the largest number using nested if-else statement

#include <stdio.h>
	int main()
	{
	double n1, n2, n3;
	printf("Enter three numbers: ");
	scanf("%lf %lf %lf", &n1, &n2, &n3);
	if( n1>=n2 && n1>=n3)
	printf("%.2lf is the largest number.", n1);
	else if (n2>=n1 && n2>=n3)
	printf("%.2lf is the largest number.", n2);
	else
	printf("%.2lf is the largest number.", n3);
	return 0;
	}
