void main()
{
    int a, b, c;
    printf("Enter three no.s:");
    scanf("%d %d %d", &a, &b, &c);
 
    if (a > b)
        if (a > c)
            printf("Max. = %d", a);
        else
            printf("Max. = %d", c);
    else if (b > c)
        printf("Max. = %d", b);
    else
        printf("Max. = %d", c);
