Yet another issue came up. Everything works just fine, but all that's left is to figure out how to put each input up in separate arrays, so the searching function I created would work properly. Whenever I put a couple of orders, then try and search via code (codigo), it only detects the most recent entry. I know the solution has something to do with malloc() and/or strcpy(), but I don't know the how or where of it.

Translation: Case 1: Make an order Case 2: Search your order (via code) Case 3: List of orders Case 4: Exit

[If I remove every fflush(), it just lets me put the name, and leaves everything else empty, so I have to keep fflush().]

Here's the code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>

#define TAM 100

typedef struct order
{
    char nome[50];
    char endereco[150];
    char pedido[300];
    char valor[10];
};

int main() 
{
    struct order lista[TAM];
    int busca, acha, i, menu;
    i = 0;
    menu = 0;
    int codigo = 0;
    int c = 0;
    
    while(menu != 4)
    {
        system("cls");
        
        printf("====================\n");
        printf("Selecione uma opcao\n");
        printf("====================\n");
        printf("1 - Cadastrar pedido\n");
        printf("2 - Consultar pedido\n");
        printf("3 - Emitir relatorio\n");
        printf("4 - Sair\n");
        scanf("%d", &menu);
        fflush(stdin);
        
        switch(menu)
        {
            case 1:
                system("cls");
                
                
                printf("Digite seu nome: \n");
                scanf("I[^\n]", lista[i].nome);
                fflush(stdin);
                
                printf("Digite seu endereco: \n");
                scanf("9[^\n]", lista[i].endereco);
                fflush(stdin);
                
                printf("Digite seu pedido: \n");

EDIT: Sorry for not mentioning what I'm working on. This is sort of a food ordering system, where you put your name, address, what you want to order, and the amount of money you wish to pay. It's a college project so nothing too much is required.

CodePudding user response：

you dont need to search, the input number is the index of the entry, just check that its not out of range

        case 2:
            system("cls");
            
            printf("Insira o codigo que deseja buscar:\n");
            scanf("%d", &busca);
            fflush(stdin);
            

                if(busca < codigo)
                {

                    printf("=============================\n");
                    printf("Codigo: %d\n", busca );
