判断输入的三个数是否相等。算法如下，请改正程序中的错误，使它能得出正确的结果。

#include <stdio.h>

main()
{
int a, b, c;

scanf("%d,%d,%d", a, b, c);
if (a = = b = = c)
    printf("The three number is equal!!!");
else
    printf("The three number isn't equal!!!");

}

#include <stdio.h>

main()
{
    int a, b, c;

    scanf("%d %d %d", &a, &b, &c);
    if (a == b && b == c)
        printf("The three number is equal!!!");
    else
        printf("The three number isn't equal!!!");

    return 0;
}
