下面程序的功能是从终端上输入5个人的年龄、性别和姓名，然后输出。请填空。 #include "stdio.h" struct man { char name[20]; unsigned age; char sex[7]; }; void data_in(struct man *p, int n ) { struct man *q = [填空(1)] ; for( ;p { printf( "age:sex:name" ); scanf("%u%s", &p->age, p->sex); [填空(2)] ; } } void data_out( struct man *p, int n ) { struct man *q = [填空(3)] ; for( ;p printf("%s;%u;%s\n", p->name, p->age, p->sex); } int main ( ) { struct man person[5]; data_in(person,5); data_out(person,5); return 0; }
