我知道它非常简单,但我无法找出变量t
的用途。
int main() {
int a, b, x, y, t, gcd, lcm;
printf("Enter two integers\n");
scanf("%d%d", &x, &y);
a = x;
b = y;
while (b != 0) {
t = b;
b = a % b;
a = t;
}
gcd = a;
lcm = (x*y)/gcd;
printf("Greatest common divisor of %d and %d = %d\n", x, y, gcd);
printf("Least common multiple of %d and %d = %d\n", x, y, lcm);
return 0;
}
如果我删除 variable 的使用t
,则输入必须按降序给出(即最高输入优先)。如果t
使用一切正常。我对编程很陌生,所以请帮忙。
