我收到以下错误,当我试图编译我的项目在Visual Studio 2012:的Visual Studio 2012 “语法错误”

这里是main.c中的代码
#include <stdlib.h>
#include <stdio.h>
double a ;
double b ;
double ComputeMaximum(double, double) ;
double ComputeMinimum(double, double) ;
int main(void)
{
printf("\nPlease enter two numeric values for comparison\n") ;
scanf("%d%d", &a, &b);
double answerMax = ComputeMaximum(a, b) ;
double answerMin = ComputeMinimum(a, b) ;
printf("Of %d and %d the minimum is %d and the maximum is %d\n", a, b, answerMin, answerMax) ;
printf("%d", answerMax) ;
printf("%d", answerMin) ;
system("pause");
return 0;
}
这里是ComputeMinimum.c
double ComputeMinimum(double a, double b)
{
double result = 0 ;
(a > b) ? (b = result) : (a = result) ;
return result ;
}
这里的代码被用于ComputeMaximum.c
的代码double ComputeMaximum(double a, double b)
{
double result = 0 ;
(a > b) ? (a = result) : (b = result) ;
return result ;
}
在MS世界的头,C仍然是C89和所有变量都必须在声明函数的顶部。忍受这一点,或得到一个真正的C编译器。 –
无关:您可能需要更长时间观察ComputeMaximum和ComputeMinimum,因为除了返回0之外,它们都不执行任何操作(并且在进程中将两个按值参数中的一个设置为0)。 – WhozCraig
哎呀,谢谢大卫! –
