可能重复:
Android API,如java.awt.Robot

在java中是否还有像Robot类一样的其他类,或者我们可以在android中使用Robot类吗？

这是函数指针程序:demo.c

#include <stdio.h>
#include <math.h>

void tabulate(double (*f)(double), double first, double last, double incr);

int main(void) {

    double final, increment, initial;

    printf("Enter initial value: ");
    scanf("%lf", &initial);

    printf("Enter final value: ");
    scanf("%lf", &final);

    printf("Enter increment: ");
    scanf("%lf", &increment);

    printf("\n      x       cos(x)"
           "\n   -------    -------\n");
    tabulate(cos, initial, final, increment);
    return 0;
}

void tabulate(double (*f)(double), double first, double last, double incr) {
    double x;
    int i, num_intervals;

    num_intervals = ceil((last - first)/incr);
    for(i=0; i<=num_intervals; i++) {
        x = first + i …

如果函数在C++中定义如下:

char *Func() {

 return "Text";
}

然后;

Func()[] = 'a';

意味着什么？
