人员的记录由编号和出生年、月、日组成,N名人员的数据已在主函数中存入结构体数组std中。函数fun的功能是:找出指定出生年份的人员,将其数据放在形参k所指的数组中,由主函数输出,同时由函数值返回满足指定条件的人数。 #include #define N 8 typedef struct { int num; int year,month,day ; }STU; int fun(STU *std, STU *k, int year) { int i,n=0; for (i=0; i if( std[i].year==year) k[n++]= std[i] ; /**********found**********/ return (______); } main() { STU std[N]={ {1,1984,2,15},{2,1983,9,21},{3,1984,9,1},{4,1983,7,15}, {5,1985,9,28},{6,1982,11,15},{7,1982,6,22},{8,1984,8,19}}; STU k[N]; int i,n,year; printf("Enter a year : "); scanf("%d",&year); n=fun(std,k,year); if(n==0) printf("\nNo person was born in %d \n",year); else { printf("\nThese persons were born in %d \n",year); for(i=0; i printf("%d %d-%d-%d\n",k[i].num,k[i].year,k[i].month,k[i].day); } }
