/* static storage program example */

#include <stdio.h>

#define MAXNUM 3


void sum_up(void);


int main(void)


int count;


printf("\n*****static storage*****\n");

printf("Key in 3 numbers to be summed ");

for(count = 0; count < MAXNUM; count++)



return 0;



void sum_up(void)


/* At compile time, sum is initialized to 0 */

static int sum = 0;

int num;


printf("\nEnter a number: ");

/* scanf("%d", &num); */

scanf_s("%d", &num, 1);

sum += num;

printf("\nThe current total is: %d\n", sum);
