while 循环语句.

#include <stdio.h>

int main() { int i = 0; while(i<3000){ printf("%d.I miss you \n", i+1); i++; }

return 0;

}

运行结果如下:

#include <stdio.h>

int main() { while(1){ int year; printf("\n请输入一个年份:"); scanf("%d,&year"); if(year%100!=0 && year%4==0||year%400==0) printf("%d 是闰年\n",year); else { printf("%d 不是闰年\n",year); } } return 0;

}

#include <stdio.h>

int main() { // s = 1 + 2 + 3 + 4 + 5 + ...+ 100

int s = 0;
int i = 1;
while(i <= 100){
	printf("%d \n", i);
	s = s + i;
	i++;	
}
printf("%d \n",s);

return 0;

}

运行结果如下：

#include <stdio.h>

int main() { // s = 1 + 2 + 3 + 4 + 5 + ...+ 100

int s = 0;
int i = 1;
while(i <= 100){
	printf("%d \n", i);
	s = s + i;
	i+=2;	
}
printf("%d \n",s);

return 0;




return 0;

}

运行结果如下：

#include <stdio.h>

int main() { // s = 1 + 2 + 3 + 4 + 5 + ...+ 100

int s = 0;
int i = 2;
while(i <= 100){
	printf("%d \n", i);
	s = s + i;
	i+=2;	
}
printf("%d \n",s);

return 0;




return 0;

}

运行结果如下：
