本示例使用函数指针数组，每个数组元素为函数名字，即函数地址，现在大部分的菜单系统都
使用类似的方法，对于要实现多项菜单选择的系统有实际参考意义。
#include <STDIO.H> void func1( int element ) { printf( "now you enter function 1, the element is %d/n", element ); } void func2( int element ) { printf( "now you enter function 2, the element is %d/n", element ); } void func3( int element ) { printf( "now you enter function 3, the element is %d/n", element ); } int main() { int choice; void (*funcptr[])(int) = { func1, func2, func3 }; printf( "please enter the choice from 1 to 3/n" ); do { scanf( "%d", &choice ); if (choice<=3 && choice>0) { (*funcptr[choice-1])(choice); } } while (choice<=3 && choice>0); return 0; }
