c语言指针函数和函数指针
C语言函数指针:
#include <stdio.h>
int sum(int a, int b){
return a+b;
}
int main(){
int (*p)(int,int);
p = sum;
printf("%d", p(1,34));
return 0;
}
C语言指针函数:
#include <stdio.h>
char *fun(char *s1, char *s2){
char *p = s2;
while((*s2++= *s1++) != '\0');
return s2;
}
void main(){
char s1[] = "hello";
char s2[128];
char *p=fun(s1, s2);
printf("%s", s2);
}
