Nettet(37)已有如下数组定义和f函数调用语句,则在f函数的说明中,对形参数组array的正确定义方式为 int a[3][4]; f(a); A)f(array[3][4]) B)f(int array[3][]) C)f(int array[][4]) D)f(int array[][]) (38)下面程序的输出结果为 main() { int a,b;b=(a=3*5,a*4,a*5); printf("%d",b);} A)60 B)75 C)65 D)无确定值 ... int (*a) [5] - Here "a" is a pointer to the array of 5 integers, in other words "a" points to an array that holds 5 integers. Example : #include int main () { int b = 3; int c = 4; int *a [2] = {&b, &c}; // is same as ---int *a [] = {&b, &c} printf ("value pointed to by a [0] = %d, by a [1] = %d\n", *a [0], *a [1]); return 0; }
