I don't know what's wrong with my code...

The function 'add' just doesn't return the variable 'sum'...

#include <stdio.h>

int add (int *p)

{

    int a, sum=0, i;

    for (a=0; a<5; a++)

    {

        sum=sum+*(p+a);

    }

    [COLOR="Blue"]return sum;[/COLOR]

}

int main()

{

    int i, ia[5]={56,36,21,48,76}, *ip;

    add (&ia[0]);

    getchar();

    return 0;

}

Please help me. Thanks~:)

try like this ... you should to declare i=....

#include <stdio.h>

#include <iostream>


int add (int *p)


{

    int a, sum=0, i=0;

   

	for (a=0; a<5; a++)

    {

        sum=sum+*(p+a);

    }

    return sum;

}


int main()


{

   

	int i=0, ia[5]={56,36,21,48,76}, *ip=0;

   

	add (&ia[0]);

   

	getchar();

    system("pause");

	return 0;

}

It returns, but you don't assign it to anything.

Also

add (&ia[0]);

can be written as

add (ia);

Really the big problem is that you're not outputting anything.
