你把子函数放到外面，或直接把算式放到sun(a,b)那，把它换掉 #includevoid main()float Sum(int i,int j);{int a, b;printf("Enter a,b:");scanf("%d,%d",&a,&b);printf("Sum=%f\n",Sum(a, b));}float Sum(int i,int j){ float k=(i-j)/2.0+(i+j)/2.0;return k;}或#includevoid main(){int a, b;printf("Enter a,b:");scanf(...

#includeint Sum(int i,int j);void main(){int a, b;//int Sum(int i,int j);//对函数的声明最好放在调用函数外面printf("Enter a,b:");scanf("%d,%d",&a,&b);printf("Sum=%d\n",Sum(a, b));}...
