Thread: Help can't put this to work

Hello, my name is João, i'm from Portugal so forgive me in advance for any writing errors.

I have a piece of C code that I can't put it to work correctly and I was hoping you can help me on this.

The objective of this program is to have 2 generic function, one for reading integers and another for reading strings, both to be applied on many other functions each one with a different question.

Code:

#include <stdio.h>

int ler_int (){
    int num;

    scanf(" %d", &num);
    
    return num;
    

}

char* ler_char (char *frase, int max){

    fgets(frase, max, stdin);
    return frase;

}

int le_nss (){
    printf ("Qual o seu numero de segurança social?:  ");
    
    return ler_int();


}

char *le_nome(char *nome){
    printf ("qual é o seu nome?: ");
    int max = 100;

    return ler_char(nome, max);
}

main(){
    char id_nome[100];
    int NSS = le_nss();

    le_nome(id_nome);

    printf("o seu numero de NSS é: %d\n", NSS);
    printf("o seu nome é: %s\n", id_nome);
}

I'm learning about pointers and it's a little bit confusing for me the use of them so probably the problem lies in the incorrect use of pointers but I can't seem to figure it out.

Thanks for the help

When you read the integer in ler_int, the Enter key leaves a newline character ('\n') in the input buffer. The function fgets reads up to -- and including -- a newline character, so it gets that newline and returns a string with just that newline character. The quickest way to fix this is to add a call to getchar() after you read the integer.

Still not working

I've tried already insert "fflush(stdio); " before the fgets, still the same result.

This is the output:

--- Qual o seu numero de segurança social?: 3456
o seu numero de NSS é: 3456
qual é o seu nome?: O seu nome é:
