For 循环读取和打印值

Question

I am using for-loops to read and print the values. As you can see it stores only the last input. Any suggestions?

#include <stdio.h>
int main()
{
    int i;
    for(int a = 0; a < 5; a ++)
    {
        printf("Enter your age: ");
        scanf("%d", &i);
    }
    for(int b = 0; b < 5; b ++)
    {
        printf("Hi I'm %d years old\n", i);
    }
    return 0;
}

And here's the output . .

Enter your age: 11
Enter your age: 22
Enter your age: 33
Enter your age: 44
Enter your age: 55
Hi I'm 55 years old
Hi I'm 55 years old
Hi I'm 55 years old
Hi I'm 55 years old
Hi I'm 55 years old

Answer 1

Your problem is that your are only storing the last answer you receive. The simplest solution that I can give you is to use array:

#include <stdio.h>
int main()
{
    int ages[5];
    for(int i = 0; i < 5; i++)
    {
        printf("Enter your age: ");
        scanf("%d", &ages[i]);
    }
    for(int i = 0; i < 5; i++)
    {
        printf("Hi I'm %d years old\n", ages[i]);
    }
    return 0;
}
