如何使用 scanf c 获取多个输入

Question

#include <stdio.h>

int main()
{
    char name[10];
    int birth_year;
    
    printf("Enter your name : ");
    scanf("%c",name);
    
    printf("Enter your birth year : ");
    scanf("%i",&birth_year);
    
    int age = 2020 - birth_year;
    printf("Your age is %i",age);
}

I am trying to take the value of birth_year as an input but it automatically assigns it to 0 for some reason what am I doing wrong

Answer 1

In the first scanf you should read a string instead of a char, that should do it. Also, it's always good to have a whitespace before you read a char, so it resets the buffer memory.

#include <stdio.h>
int main()
{
    char name[10];
    int birth_year;

    printf("Enter your name : ");
    scanf(" %s",name);

    printf("Enter your birth year : ");
    scanf(" %d",&birth_year);

    int age = 2020 - birth_year;
    printf("Your age is %i",age);
}
