基于这句话，integerPower是指一个函数，你看编写一个函数，后面跟随了一个复杂的东西，那么很显然，这就和编写一个函数abcdefg差不多是一个意思，abcdefg就是指的编写一个函数中的“函数”这个意思。所以，结论就是，integerPower是指一个函数。至于返回的意思吗……你去搜索一下C的关键字，其中有一个关键字叫做return，翻译成汉语就是返回。

The pow function returnsxraised to the power ofy. If x is negative and y is not an integer value, the pow function will return a domain error. Required Header In the C Language, the required header for the pow function is: #include <math.h> ...

c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///< 2个参数printf("%d, %d", a, b);///< 3个参数 测...
calculateSum();// call the function return0; } // Outputs The sum of x + y is: 15 Try it Yourself » This was just an example to demonstrate a simple function with different statements in C. The real power of a function is revealed in the next chapter, when we pass "parameters"...

If the function does not return a value, you can omit the return specification or specify it as void. The following table shows valid function specification syntax for an integer return value. Use the table to identify the syntax you should use for your C function prototyp...
printf("Input an integer for i(0~15):"); scanf("%d", &num.i); printf("i = %d, cba = %d %d %d\n", num.i, num.bits.c, num.bits.b, num.bits.a);return0; } 输入i值为11,则输出为i = 11, cba = -2 -1 -1。
