么么哒

part 1  我觉得实践是检验真理的唯一标准，还是要多动手，多看书。

part 2 

 1 #include<stdio.h>
 2 int main () {
 3     int x;
 4 printf("输入一个整数: \n");    
 5  scanf("%d",&x);
 6  if(x%2==1)
 7  printf("是奇数");
 8  else
 9  printf("是偶数") ;
10  return 0 ;
11 }

 1 #include<stdio.h>
 2 int main(){
 3  char ch;
 4  printf("输入一个字符；\n");
 5  scanf("%c",&ch);
 6  if(ch>='a'&&ch<='z')
 7  ch=ch-32;
 8  else
 9  scanf("ch\n");
10  return 0;
11 }
12  

 1 #include<stdio.h>
 2 int main (){
 3   int days;
 4    printf("输入一个整数: \n");
 5    scanf("%d",&days); 
 6    if(days>=1&&days<=5)
 7      printf("workdays,fighting\n");

 

 8    else if(days<=7&&days>=6)
 9      printf("weekdays,relax~\n");
10     else
11    printf("Ooops, not in 1~7\n");
12    return 0;
13 }
