TO CALCULATE THE SUM OF THE ARRAY ELEMENT USING POINTERS AND FUNTIONS

AIM

             To write a C program to illustrate parameter passed to the function.

ALGORITHM

Step-1: Start the program

Step-2: Enter the size of the array

Step-3: Enter the elements of the array

Step-4: Print the array elements

Step-5: Call the function with base address of the array passed to it

Step-6: In the calling function gets the base address in the pointer variable

Step-7: Add the array elements

Step-8: Return the value from the calling function to the variable in the called function

Step-9: Print the sum in the called function

Step-10: End the program in the main function

PROGRAM

#include<stdio.h>

main()

{

            int a[10],i,no,sum=0;

            printf(“Enter the size of array...”);

            scanf(“%d”,&no);

            printf(“Enter the elements of the array...”);

            for(i=0;i<no;i++)

                        scanf(“%d”,&a[i]);

            for(i=0;i<no;i++)

                        printf(“\n%d”,a[i]);

            sum=add(&a[0],no);

            printf(“\nThe sum of %d numbers is...%d”,no,sum);

}

add(int *pt,int n)

{

            int i,a=0;

            for(i=0;i<n;i++)

            {

                        a=a+*pt;

                        pt++;

            }

return(a);

}

OUTPUT

Enter the size of array... 5

Enter the elements of the array...

1                      2          3          4          5

1                      2          3          4          5

The sum of 5 numbers is... 15

RESULT: Thus a c program to find the substring from a given string is implemented.
