C language study notes circulating structure - for statement

Hello, everyone, to start learning it today - cycle structure

Wherein the loop structure comprises:

• for statement
• while statement
• do whlie statement

Second, also you need to get:

• break statement
• continue Statement

Well start today's study notes:

For statement:

for(循环变量初值;条件表达式;循环变量体增值)

Equivalent to

for (;条件表达式;)
{
	循环体
	循环变量增值
}

Loop body can be written in different forms according to the meaning of the questions, which require analysis tool has to ask friends ~

Example: chickens and rabbits with cage problem: a total of 100 chickens and rabbits, a total of 274 feet, and besought chickens, rabbits have how many?

Analysis: The relationship between chickens and rabbits for the chicken :( set only for the x, y is the only rabbit)

x + y = 100
2 x 4 + y = 278

#include <stdio.h>
int main ()
{
	int x,y;
	for(x=1;x<100;x++)
	{
		y = 100 - x;
		if (x * 2 + y * 4 == 274 )
		printf("鸡有：%d只，兔有：%d只\n", x,y);
	}
}

This program is thinking -
knock when the code must be careful carefully, open your eyes Atlanta card position, do not sign anything less (like me)!

Thank you see here! Goodnight everybody! see u tomorrow!
Tomorrow add some examples, along with "well-informed"
