【c语言】有一个函数： x < 1 --- y = x 1 <= x < 10 --- y = 2 * x - 1 x >= 10 --- y = 3 * x - 11 输

// 有一个函数：// x < 1 --- y = x      1 <= x < 10 --- y = 2 * x - 1    x >= 10 --- y = 3 * x - 11// 输入x,求y#include <stdio.h>int main(){int x,y;printf("请输入x值：");scanf("%d",&x);if(x < 1)y = x;else if(x >= 1 && x < 10)y = 2 * x - 1;elsey = 3 * x - 11;printf("对应的y值是：%d\n",y);return 0;}<img src="http://img.blog.csdn.net/20150423122634210?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvemhhb3lhcWlhbjU1Mg==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" /><img src="http://img.blog.csdn.net/20150423122757817?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvemhhb3lhcWlhbjU1Mg==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" /><img src="http://img.blog.csdn.net/20150423122651822?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvemhhb3lhcWlhbjU1Mg==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" />
