c语言求平均值改错

stdio;The average is "a).h> void main() { int x,y,a; scanf("%f%f",x,y); a=(x+y)/2; Printf(&quot找出并改正以下源程序中错误，得出正确的运行结果。（该源程序为average.cpp文件） 源程序如下： #include &lt

&x,&y);/Printf改成printf；The average is 后需加上格式控制符%f并在a前加逗号
}
就这些了,y,a;/加上取地址符&
a=(x+y)/#include <,a);stdio;第一个错误将int更改成float
scanf("%f%f".h>
main()
{
float x;
printf("The average is %f"//2;//

#include void main() { double x,y,a; //这里用 double scanf("%f%f",&x,&y); //这里加 取地址符& a=(x+y)/2; Printf("The average is %f",a); //这里加输出类型 %f（浮点型）

scanf("%d%d", &x, &y);        a=(x+y)/2; Printf("The average is %d", a);

scanf("%f%f",&x,&y); //取地址符 Printf("The average is %f",a); int x,y,a; 改为 foat x,y,a;

#include #define n 10 double fun(double x[],double *y) { int i,j; double av; av=0; for(i=0; iav) y[j++]= x[i]; y[j]=-1; return av; } main() { int i; double x[n],y[n]; for(i=0; i=0; i++) printf("%5.1f ",y[i]); printf("\n"); }

stdio.h> void main() { float x,y,a; scanf("%f%f",x;,a) #include <The average is %f\n"数据类型要用float，printf是小写的而且后面引号里应该写成(",y); a = (x + y)/2; printf(&quot...%f&quot
