打印前10个偶数自然数的C语言程序

编写一个C语言程序，使用for循环打印前10个偶数自然数。

#include <stdio.h>

int main()
{
	printf("The First 10 Even Natural Numbers are\n");
	for (int i = 1; i <= 10; i++)
	{
		printf("%d\n", 2 * i);
	}
}

这个C程序使用while循环显示前10个偶数自然数。

#include <stdio.h>

int main() { printf("The first 10 Even Natural Numbers are/n");

int i = 1;

while (i <= 10)
{
	printf("%d\\n", 2 \* i);
	i++;
}

The First 10 Even Natural Numbers are
2
4
6
8
10
12
14
16
18
20

这个C程序使用do while循环来打印前10个偶数自然数。

#include <stdio.h>.

int main() {

printf("The First 10 Even Natural Numbers are\\n");

int i = 1;

do
{
	printf("%d\\n", 2 \* i);

} while (++i <= 10);

The First 10 Even Natural Numbers are
2
4
6
8
10
12
14
16
