Getting error: expected expression before ‘{’ token in C while trying to verify struct-CodePudding

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

#define LEN_ID 3
#define LEN_P 30
#define LEN_CIDADE 50
#define AT 40

typedef struct aeroporto
{
    char id[LEN_ID   1];
    char pais[LEN_P   1];
    char cidade[LEN_CIDADE   1];
} Aeroporto;

int findavailablespot(Aeroporto l[AT])
{
    int i = found = 0;
    for (;i<AT;i  ) {
        if (l[i] = {"aaa","bbb","ccc"}) //Error in this line
            break;
        if (found)
            return i;
        else
            return -1;
    }    
}

So i am creating the structure aeroporto then a vector made up of aeroportos and i want to check if {"aaa","bbb","ccc"} shows up inside the vector. Help?

Sorry for the formatting, new at this

CodePudding user response：

You have to use strcmp() to compare strings. There's no shortcut for doing this with all the members of a structure, you have to test each one individually and combine with &&.

You also forgot to set found before breaking out of the loop.

int i = 0, found = 0;

for (;i<AT;i  ) {
    if (strcmp(l[i].id, "aaa") == 0 && strcmp(l[i].pais, "bbb") == 0 && strcmp(l[i].cidade, "ccc")) {
        found = 1;
        break;
    }
}
