help setting char inside the if in C

Question

Hello, I’m trying to set the char variable filename[100] inside if, but the compiler error, but if I set it outside of if it works good, any pls help? (#defines are stdio. h stdlib. h time. h and locale. h)

void selecionarPersonagem(int opcaoPersonagem);

char tipoPersonagem[3][100] = {{"Lutador"}, {"Ninja"}, {"Apelão"}};
char tipoArma[3][100] = {{"Faca"}, {"Pistola"}, {"Socão"}};

int main()
{
    //Definição para acentos e cedilha
    setlocale(LC_ALL, "Portuguese");

    int flag = 0;
    do{
        int opcaoPersonagem;
        printf("Escolha seu personagem:\n");
        printf("[1] All Might.\n");
        printf("[2] Bulma.\n");
        printf("[3] Kirito.\n");
        printf("[4] Naruto.\n");
        scanf("%i", &opcaoPersonagem);
        if(opcaoPersonagem < 1 || opcaoPersonagem > 4)
            printf("Opção inválida, tente novamente.");
        else{
        selecionarPersonagem(opcaoPersonagem);
        }
    }while(flag == 0);

    return 0;
}

void selecionarPersonagem(int opcaoPersonagem)
{
    FILE *fptr;
    char c;
    if(opcaoPersonagem == 1)
        char filename[100] = "personagem1.txt"
    fptr = fopen(filename, "r");
    c = fgetc(fptr);
    while(c != EOF){
        printf("%c", c);
        c = fgetc(fptr);
    }
    fclose(fptr);
}

if(opcaoPersonagem == 1){
    FILE *fptr;
    char c;
    char filename[100] = "personagem1.txt";
    fptr = fopen(filename, "r");
    c = fgetc(fptr);
    while(c != EOF){
        printf("%c", c);
        c = fgetc(fptr);
    }
    fclose(fptr);
}

The mistake you’re pointing to is somewhere else, filename was not identified in fopen(filename, "r");. You have a static semantic error, the variable filename has to be declared in the same scope as is being used. if without opens and closes keys only considers the first instruction after.
