1.概念填空题

#include<stdio.h>
int main() {
 int k, x;
 for (k = 0, x = 0; k <= 9 && x != 10; k++) {
  x += 2;
 }
 printf("%d,%d", k, x);
}

 

 

 

#include<stdio.h>
int main()
{
 char c;
 for (c = getchar(); getchar() != '#'; c = getchar())
 putchar(c);
 return 0;
}

2.单项选择

 

 

#include<stdio.h>
int main()
{
 char ch;
 for (; (ch = getchar()) != '\n';)
  printf("%c", ch);
 return;
}

 3.阅读程序

 

#include<stdio.h>
int main()
{
    int i;
    for (i = 1; i < 6; i++)
    {
        if (i % 2)
            printf("*");
        else
            printf("#");
    }
    return 0;
}
