Getting next line near country?

Question

#include <stdio.h>

#define max_size 57

int main(void){
int bags, weight;
bags = weight = 0;
//Longest know country name is 56 characters
char country[max_size];

printf("What country did you fly in from?\n");
fgets(country, max_size, stdin);

printf("How many bags did you have?\n");
scanf("%i", &bags);

printf("What was the total weight of all bags?\n");
scanf("%i", &weight);

printf("I flew from %s having %i bags with average weight of %i\n", country, bags, weight/bags);

return 0;
}

Answer 1

Thanks I got it!!!

Answer 2

fgets gets every character in the input stream up to a max that you set. If the country name is less than 57 characters, fgets will swallow the '\n' character when RETURN is pressed to enter the country name.

There's probably a way to do it with fgets but i prefer scanf. Change the line to:

scanf("%s", country); // and you'll get your expected output

Answer 3

scanf("%s", country) allows for buffer overflow someone typing 58 characters will crash the program. That is why I suggested fgets as previously stated.
