why does the age in the search function not printing? - c

Question

I was asked to make a hash table program which input name and age. I declared name and age as char. While doing the search function, I need to print the name and the age but the age do not print. What is wrong with my code?
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<ctype.h>
int n;
int count;
struct data
{
char name [100];
char age[5];
struct data *next;
};
struct data *chain[100000];
struct data* insert(char name[], char age[]){
struct data *curr = (struct data*) malloc (sizeof(data));
strcpy(curr->name, name);
strcpy(curr->age, age);
curr->next = NULL;
return curr;
};
//hash function
int hashing(char name[]){
int first = name[0];
return first % n;
}
//buat tau di index ke x dia data ke brp
void add(struct data *newNode){
int hash = hashing(newNode->name);
printf("index->%d\n", hash);
if(chain[hash] == NULL){
chain[hash] = newNode;
}
else
{
struct data *temp = chain[hash];
while(temp->next != NULL){
temp = temp->next;
//count++;
}
count++;
temp->next = newNode;
//count++;
}
printf("data-> %d\n", count);
}
void view(){
for(int i = 0 ; i < n ; i ++)
{
int count = 0;
if(chain[i]!=NULL){
printf("=== index %d data ===\n", i );
struct data *temp = chain[i];
while(temp!=NULL){
printf("data %d\n", count);
printf("name=%s age=%s\n", temp->name, temp->age);
temp = temp->next;
count ++;
}
}
}
printf("\n");
}
void search(int hash){
char age[5];
char search[100];
printf("Search name:");
scanf(" %[^\n]s", search);
int key = hashing(search);
printf("Search data %s from index %d data....\n", search, key);
if(strcmp(chain[key]->name, search)==0){
printf("data found at node %d\n", key);
printf("name = %s age = %s\n", search, age);
}
else
{
struct data *temp = chain[key];
while(temp->next!=NULL){
if(strcmp(chain[key]->name, search)==0){
printf("data found at node %d\n", key);
printf("name = %s age = %s\n", search, age);
}
temp = temp->next;
}
if(strcmp(temp->name, search)==0 && temp->next==NULL){
printf("data found at node %d\n", key);
printf("name = %s age = %s\n", search, age);
}
else{
printf("no data found!\n");
}
}
}
//void remove(int hash){
// //int key = item->key;
// int hash = hashing(key);
// int option;
// printf("input option:");
// scanf("%d", &option);
// char search[100];
// printf("delete name:");
// scanf(" %[^\n]s", search);
// int first = search[0];
// int key = first % n;
// printf("Search data %s from index %d data....\n", search, key);
// if(chain[key]==hash){
// chain[key]=-1;
// }
// else
// {
// printf("try");
// }
//}
int main(){
char name[100];
char age[5];
printf("input the number of hash table: ");
scanf("%d", &n); getchar();
struct data *chain[n];
int chainSize[n]={0};
printf("\n");
int option;
do{
printf("=== Option Menu ===\n");
printf("1. insert data\n");
printf("2. delete data\n");
printf("3. search data\n");
printf("4. view data\n");
printf("5. exit\n");
printf("input option: ");
scanf("%d", &option); getchar();
switch(option){
case 1:{
printf("input name: ");
scanf(" %[^\n]s", name);
printf("input age: ");
scanf(" %[^\n]s", age);
add(insert(name,age));
printf("\n");
break;
}
case 2:
{
//remove();
break;
}
case 3:
{
search(n);
break;
}
case 4:
{
view();
break;
}
}
}while(option!=5);
}
the output is like this
name = hansol
age =
when it is supposed to be like this:
name = hansol
age = 23
so the age variable does not print while doing the search function
