这是一个输入年，月，日，名字，收入后打印出一条信息的程序，请问该怎么改？

Question

#include <stdio.h>#include <stdlib.h>#define MAX 100#define YES 1#define NO 0struct record {char fname[15+1];char lname[20+1];char phone[9+1];long income;int month;int day;int year;};struct record list[MAX];int last_entry = 0;int main(void);void get_data(void);void display_report(void);int continue_function(void);void clear_kb(void);int main( void ){int cont = YES;int ch;while( cont == YES ){printf( "\n");printf( "\n MENU");printf( "\n ========\n");printf( "\n1. Enter names");printf( "\n2. Print report");printf( "\n3. Quit");printf( "\n\nEnter Selection ==> ");ch = getchar();fflush(stdin); /* remove extra characters from keyboard buffer */switch( ch )

Answer 1

for ( cont = YES; last_entry < MAX && cont == YES;last_entry++ )
看到这个循环了么 如果执行到这里 last_entry就变化了

Answer 2

for ( cont = YES; last_entry < MAX && cont == YES;last_entry++ )这句中把last_entry的值修改了，该变量的值大于等于1，小于等于MAX。
