函数指针数组小例子

[root&＃64;lex tst]# cat gao3.c
#include
#include <string.h>char * function1 (char *p)
{printf("In function1 %s\n",p);return p;
}char * function2 (char *p)
{printf("In function2 %s\n",p);return p;
}char * function3 (char *p)
{printf("In function3 %s\n",p);return p;
}int main()
{char * (*pf[3]) (char *p);pf[0] &＃61; function1;pf[1] &＃61; &function2;pf[2] &＃61; &function3;pf[0]("func1");pf[1]("func2");pf[2]("func3");return 0;
}
[root&＃64;lex tst]#

[root&＃64;lex tst]# gcc -o gao3 gao3.c
[root&＃64;lex tst]# ./gao3
In function1 func1
In function2 func2
In function3 func3
