语法-循环

新建项loop.c
1.while
将branch.c最后一个main方法的名改为main23

#include <stdio.h>

int main(void) {
	int num = 0, sum = 0;
	while (num < 100) {
		sum += num;
		num++;
	}
	printf("%d",sum);
	return 0;
}

2.for
将上一个main方法的名改为main31

int main(void) {
	int sum = 0;
	for (int i = 0; i < 100; i++)
	{	
		sum += i;
	}
	printf("%d",sum);
	return 0;
}

3.do...while
将上一个main方法的名改为main32

int main(void) {
	int num = 0, sum = 0;
	do
	{
		sum += num;
		num++;
	} while (num < 100);
	printf("%d",sum);
	return 0;
}

ps:
1.for循环遵循C99标准
