C语言.编写程序,根据用户输入的x和y值来计算xy的值。要求编写power(x,y)函数,来实

Answer 1

#include <stdio.h>

power(float a,float b)
{
float sum1=a*b;
return sum1;
}

void main()
{
float x,y;
float sum;
printf("input the first number:\n");
scanf("%f",&x);
printf("input the second number:\n");
scanf("%f",&y);
sum=power(x,y);
printf("xy is %f\n",sum);

}

发完了才看到如楼上的差不多，呵呵

Answer 2

#include <stdio.h>

power(float a,float b)
{
float sum1=a*b;
return sum1;
}

int main()
{
float x,y;
float sum;
printf("input the first number:\n");
scanf("%f",&x);
printf("input the second number:\n");
scanf("%f",&y);
sum=power(x,y);
printf("xy is %f\n",sum);

return 0;
}

编译通过
