My code don't run ,how can I fix it i think i don't understand where i am wrong error when using pointers, dynamically allocating ,struct

#include"stdio.h"
#include"stdlib.h"
#include"string.h"
struct nhanVien{
    int code;
    char name[50];
    char sex[50];
    int numb;
    int wage;
};
void input(nhanVien *worker,int n){
    for(int i=0;i<n;i  ){
        printf("Nhap ma nhanVien : ");
        scanf("%d",(worker->code i));
        
    }
}
int main(){
    nhanVien *worker;
    int n;
    printf("Nhap so luong nhan vien : ");
    scanf("%d",&n);
    worker = (nhanVien*)malloc(n*sizeof(nhanVien));
    input(worker,n);
    for(int i=0;i<n;i  ){
        printf("Nhap ma nhanVien : %d \n",*(worker->code i));
        
    }
    free(worker);
    
}

Invalid type argument of unary '*' (have 'int') Error in C this is images enter image description here

CodePudding user response：

The name nhanVien is not declared. There is declared the type specifier struct nhanVien.

So you need use this name as for example

void input( struct nhanVien *worker,int n){

or

struct nhanVien *worker;

or

worker = (struct nhanVien*)malloc(n*sizeof( struct nhanVien));

This call of scanf

scanf("%d",(worker->code i));

is incorrect. You need to write either

scanf("%d", &( worker   i )->code);

or

scanf("%d", &worker[i].code);

Also this call of printf

printf("Nhap ma nhanVien : %d \n",*(worker->code i));

is incorrect. You need to write

printf("Nhap ma nhanVien : %d \n", worker[i].code);

CodePudding user response：

I found a number of issues in your code, worker->code i should be worker[i].code; you're missing typedef on the struct type. Basically, you want something like

#include"stdio.h"
#include"stdlib.h"
#include"string.h"

typedef struct {
    int code;
    char name[50];
    char sex[50];
    int numb;
    int wage;
} nhanVien;

void input(nhanVien *worker,int n) {
    for(int i=0; i<n; i  ) {
        printf("Nhap ma nhanVien : ");
        scanf("%d", &worker[i].code);
    }
}

int main() {
    nhanVien *worker;
    int n;
    printf("Nhap so luong nhan vien : ");
    scanf("%d",&n);
    worker = (nhanVien*)malloc(n*sizeof(nhanVien));
    input(worker,n);
    for(int i=0; i<n; i  ) {
        printf("Nhap ma nhanVien : %d \n",worker[i].code);
    }
    free(worker);
}
