    (a) Write a C program that uses two user defined functions, one of the functions calculates the sum and the other calculates the product of two numbers.
    (b) Write a C program that uses pointers to calculate the sum of the elements of an array.
    (c) Write a C program that declares and initializes two variables and then write their values on a file.

    1. Correct definiton
    Code:
    int y,x=4;
    2. Assignment instruction must be in a function
    Code:
    int main()
    {
      y=x;
      // other instructions
      return 0;
    }
    3. Why do you want to display integer value as floating-point?
    Code:
    printf("\n The value of x is = [COLOR="Red"]%f[/COLOR] and the value of y is = %d",x,y);
    4.
    Compile and run the program.
