新学C语言。请大家看下。有什么不对。求改成后能输出运行后的结果。谢谢
# include<stdio.h>int main()
{
float a, b, x, y, n, m;
printf("请输入两个数字。\n");
printf("a = ",a);
scanf("%f", &a);
printf("b = ",b);
scanf("%f", &b);
x = a + b;
y = a - b;
n = a * b;
m = a / b;
printf(" 相加=%.2f\n 相减=%.2f\n 相乘=%.2f\n 相除=%.2f\n", x, y, n, m);
return 0;
}
