在主函数中, 把输入的整数i作为实参, 在printf语句中调用day-name函数并把i值传送给形参 n。day-name函数中的return语句包含一个条件表达式, n 值若大于7或小于1则把name[0] 指针返回主函数输出出错提示字符串“Illegal day”。否则返回主函数输出对应的星期名。主函数中的第7行是个条件语句,其语义是,如输入...
p_Max = &Max;//把函数Max赋给指针变量p, 使p指向Max函数printf("please enter a and b:");scanf("%d%d", &a, &b); c = p_Max(a, b);//通过函数指针调用Max函数printf("a = %d\nb = %d\nmax = %d\n", a, b, c);return0; }intMax(intx,inty)//定义Max函数{intz=-0x7FFFFFFF;...

The CDate function can also be used to convert date values from one format to another. For example, CDate(“01/01/2021”) will return a date value, while CDate(“01-01-2021”) will return an error. The CDate function is often used in conjunction with other date functions, such as...
To get more detailed information, generated function prototypes can be extracted with the scripts/flatcc-doc.sh script. Some are also concerned with macros being "unsafe". Macros are not unsafe when used with FlatCC because they generate static or static inline functions. These will trigger ...

To return the critical value of F, use the significance level as the probability argument to FINV. FINV uses an iterative technique for calculating the function. Given a probability value, FINV iterates until the result is accurate to within ± 3x10^-7. If FINV does not converge after 100...
