Jes*_*sse 3 c multidimensional-array
所以,这个节目应该从Auburn的足球赛季中获取统计数据并计算每场比赛和整个赛季的平均值,并将它们打印在屏幕上的图表中.我以为我已经想到了这一点,但在尝试编译时我一直遇到错误.我确定我也错过了其他一些东西,但是一旦我得到程序编译并给我结果,我应该想出来.如果我的老师决定教课,我可能会知道发生了什么.任何帮助将不胜感激.
以下是我得到的一些错误:
错误:预期')'在'''令牌之前 - 这显示在我的所有compAvg函数上.
错误:在']'标记之前的预期表达式 - 这一个出现在numGames = getStats行.
错误:函数"分析"的参数太少
错误:'numGames'在这里未声明(不在函数中) - 这出现在void分析函数中,我猜它与最后一个错误有关.
错误:下标值既不是数组也不是指针 - 这是我的第一个第二个printf行

当您传递数组时,您只需引用调用站点上的名称:
numGames = getStats(date[][2], oppName[], inStats[][4]);
numGames = getStats(date, oppName, inStats);
在您调用的函数中,您使用(或多或少)您显示的符号.
但是,当函数接受多维数组时,必须在函数的参数列表中指定第二维和后续维的大小.
double compAvgTD(stat[][], numGames)
double compAvgTD(double stat[][4], int numGames)
这适用于main()函数内部和函数定义中的声明.请注意,我也添加了类型.
正如另一位回答者所指出的那样,在内部声明这些功能是非常规的(尽管实际上并不是错误的)main().如果声明的函数将从任何其他函数调用,那么在内部声明函数将是不好的main()- 你必须重复自己在其他函数中声明函数,而这些函数与它们的调用相矛盾,这与敏捷格言相矛盾. :干不要重复自己.
编译代码需要进行许多更改.代码尚未运行.
此处至少还有一个错误 - 该compAvgPts()函数使用相同的统计信息cmpAvgYds(),可能会给出点数的虚增统计信息.修复需要适度大手术; 我认为你在输入中缺少两列数据(每个团队的得分).
但是,代码使用命令行使用GCC 4.2.1在MacOS X 10.6.5上进行干净编译:
gcc -O -std=c99 -Wall -Wextra -Wmissing-prototypes -Wstrict-prototypes \
-Wold-style-definition xx.c -o xx
请注意,我必须移出函数声明main(); 否则,编译器警告说范围内没有原型.
