How do you ask the User multiple questions in C? - c

Question

I am new to "C programming" and I have Googled for my answer, but I can't seem to get what I am looking for. I am making a simple 2 question program. The code is listed below:
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
char characterName[] = "Mike";
int age = 0;
printf("Enter your age, %s.\n", characterName);
scanf("%d", &age);
printf("Your being %d is old older than me and my brother "
"which was the first computer.Hahaaa.... \n", age);
return 0;
}
This is the next question:
char str[50];
{
printf("Anything to say about my comment? \n");
scanf ("%[^\n]", str);
printf("That was a good answer. I wasn't expecting that from you.\n");
return 0;
}

Answer 1

How about a function to ask a question, and return a response?
#include <stdio.h>
/*
* Prompt the user with the given question, return their
* input in answer, up to max_answer_length bytes
* returns 1 for ok, 0 on error.
*/
int askQuestion(const char *question, char *answer, const size_t max_answer_length)
{
int input_ok = 1;
// Show the user the question
printf( "%s: ", question );
// Throw away any existing input in the user's input-queue
// (like if they answered with a really-long string previously)
fflush(stdin);
// Read a line of input from the user into <answer>, but not more
// than <max_answer_length>-1 bytes are accepted (see fgets() for details)
// If the fgets() returns EOF or an error, make sure we remember it
if ( fgets( answer, max_answer_length, stdin ) == NULL )
input_ok = 0;
// return whether there was an error on input
return input_ok;
}
int main(void)
{
char answer_buffer[200];
askQuestion( "What is your favourite fruit?", answer_buffer, sizeof(answer_buffer) );
printf( ">> %s\n", answer_buffer );
askQuestion( "How long have you been programming C?", answer_buffer, sizeof(answer_buffer) );
printf( ">> %s\n", answer_buffer );
return 0;
}
