问答：C程序为何for循环和while循环无法相互替代？

百鸡百钱问题：

C代码：

include <stdio.h>

main()

{

int cock, hen, chicken;

for(cock=0;cock<=20;cock++)

for (hen = 0; hen <= 33; hen++)

{

chicken = 100 - cock - hen;/

if (5 * cock + 3 * hen + chicken / 3.0 == 100)

printf("cock=%2d,hen=%2d,chicken=%2d\n", cock, hen, chicken);

}

return 0;

}

为何使用while循环写出来的代码无法编译出结果？求解答

include <stdio.h>

main()

{

int cock=0, hen=0, chicken = 0;

while (cock <= 20)

{

while (hen <= 33)

{

chicken = 100 - cock - hen;

if (5 * cock + 3 * hen + chicken / 3.0 == 100)

printf("cock=%2d,hen=%2d,chicken=%2d\n", cock, hen, chicken);

}

hen++;

cock++;

}

return 0;

}
