死循环。while表达式一直为
#include <stdio.h>
int main(){
// 我爱你,输入三次
int i = 0;
while(i<3000){
printf("I miss you \n", i+1);
i++;
}
}
#include <stdio.h>
int main(){
while(1){
printf("hello world!");
}
while(0){
printf("hello world!");
}
while(2>1){
printf("hello world!");
}
// 输入一个年份,判断是否闰年?
while(1){
int year;
printf("请输入一个年份:");
scanf("%d", &year);
if((year%4==0 && year%100!=0) || (year%400==0)){
printf("%d 年是闰年\n", year);
}else{
printf("%d 年不是闰年\n", year);
}
}
}
求累加s=1+2+3+4+5
#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);
}
作业1: s=1+3+5+7+9+...+99
int s = 0;
int i = 1;
while(i <= 100){
printf("%d \n", i);
s = s + i;
i += 1;
}
printf("%d \n",s);
}
作业2: s=2+4+6+..+100
int s = 0;
int i = 2;
while(i <= 100){
printf("%d \n", i);
s = s + i;
i += 2;
}
printf("%d \n",s);
