C Program to Find the Largest Number Among Three Numbers

           C Program to Find the Largest Number Among Three Numbers

Code:

#include <stdio.h>
int main()
{
    double n1, n2, n3;

    printf("Enter three different 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;

}



Or


#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;

}



Or

#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;

}


Output:

Enter three numbers: -10.5
4
9.5

9.5 is the largest number.
