    1. #include<stdio.h>
    class str
    {
    char st[20];
    };
    void main()
    {
    str ob=new str();
    int asc[20],sumasc=0;
    printf("Enter string");
    scanf("%s",ob.st);
    for (i=0;i<20;i++)
    {
    asc[i]=toascii(ob.st[i]);
    sumasc=sumasc+asc[i];
    }
    printf("The sum of ascii number is",sumasc);
    }

    2.Just read 20 numbers using for loop and then use one variable as maximum set to zero and in the for loop check the current number is larger then maximum if yes set that number to maximum else continue.
