error: Program output shows ascii characters - c

Question

I seem to have an issue with the output of my program, when i choose option 1 it works fine in terms of asking me what data I would like to add with the packets, I enter numerical figures as I am supposed to but except for the data variable output it outputs strange ASCII characters instead of the numbers I originally inputted so any help would be appreciated thank you.
#include <stdio.h>
#include <stdlib.h>
struct packet{
int source[4];
int destination[4];
int type[4];
int port[4];
char data[50];
};
void main ()
{
struct packet s[50]; //Array for structure input
int choice;
int customerCount = 0, ii = 0;
while (customerCount <= 50){
printf("What would you like to do?\n");
printf("\t1) Add a packet.\n");
printf("\t2) s all packets.\n");
printf("\t3) Save packets.\n");
printf("\t4) Clear all packets.\n");
printf("\t5) Quit the programme.\n");
scanf("%i", &choice);
switch (choice)
{
case 1: printf("\n****Adding a packet*****\n");
printf("Where is the packet from?\n");
scanf("%i", &s[customerCount].source);
printf("Where is the packet going?\n");
scanf("%i", &s[customerCount].destination);
printf("What type is the packet?\n");
scanf("%i", &s[customerCount].type);
printf("What is the packet's port?\n");
scanf("%i", &s[customerCount].port);
printf("Enter up to 50 characters of data.\n");
scanf("%s", s[customerCount].data);
customerCount++;
break;
case 2: printf("\nDisplaying Infomation\n");
for(ii = 0; ii < customerCount; ii++) {
printf("\nSource: %s", s[ii].source);
printf("\nDestination: %s", s[ii].source);
printf("\nType : %s", s[ii].type);
printf("\nPort : %s", s[ii].port);
printf("\nData: %s\n---\n", s[ii].data);
}
break;
case 3: break;
case 4: break;
case 5: break;
default: printf("\nThis is not a valid choice, please choose again\n\n");
break;
}
}
}

Answer 1

You're adding input to the structure's int arrays as though they're a single int and printing them as though they're strings. Make the int arrays single ints and print them with %i as the printf format specifier.
struct packet
{
int source;
int destination;
int type;
int port;
char data[50];
};
case 2:
printf("\nDisplaying Infomation\n");
for(ii = 0; ii < customerCount; ii++)
{
printf("\nSource: %i", s[ii].source);
printf("\nDestination: %i", s[ii].source);
printf("\nType : %i", s[ii].type);
printf("\nPort : %i", s[ii].port);
printf("\nData: %s\n---\n", s[ii].data);
}
break;
