c - C 程序的错误和警告

Question

第 41 行出现错误:“int”之前有预期表达式 第 45 行:建议在 '&' 操作数的比较周围使用括号

我还想确定 43-45 中的代码是否有意义。

我是第一次在这个论坛上发帖，我是 C 新手，所以请容忍这篇文章的业余性质

#include<stdio.h>
#include<math.h>
int main(void)

{
 // LOCAL DECLARATIONS

 int bricks; //the number of bricks available
 int spheres; //the number of spheres available
 int prisms; //the number of prisms available
 int final_string(int bricks, int spheres, int prisms); //the longest possible string with the given shapes in an alternating fashion

 // EXECUTABLE STATEMENTS

 printf("\nEnter the number of bricks: ");
 scanf("%d", &bricks);
 printf("Enter the number of spheres: ");
 scanf("%d", &spheres);
 printf("Enter the number of prisms: ");
 scanf("%d", &prisms);
 printf("\nLongest possible string of alternating shapes usuing only two different shapes: %d", int final_string(int bricks, int spheres, int prisms));

 int final_string(int bricks,int spheres,int prisms);
{
 return bricks * (bricks > spheres & bricks > prisms) + spheres * (spheres > bricks & spheres > prisms) + prisms * (prisms > bricks & prisms > spheres);
}

return(0);

Answer 1

1. 从该行中删除所有 int:

   printf("\nLongest possible string of alternating shapes usuing only two different shapes: %d", int final_string(int bricks, int spheres, int prisms));
   

2. 删除final_string定义中函数签名后面的分号

3. 将 final_string 移至 main 之外
4. 使用逻辑&&运算符而不是按位&
5. 购买并阅读 a C book
6. 以后在 http://codereview.stackexchange.com 上提出这样的“问题”
