C Exercise Example 5
100 cases of classic C language
Title: Enter three integers x, y, z, please put three numbers from small to big output.
Program analysis: We find a way to put the smallest number x, the first x and y are compared, if x> y then the x and y values are exchanged, and then use the x and z are compared, if x> z x and z values will be exchanged, so make x minimum.

int main()
{
int x,y,z,t;
printf("\n请输入三个数字:\n");
scanf("%d%d%d",&x,&y,&z);
if (x>y) { /*交换x,y的值*/
t=x;x=y;y=t;
}
if(x>z) { /*交换x,z的值*/
t=z;z=x;x=t;
}
if(y>z) { /*交换z,y的值*/
t=y;y=z;z=t;
}
printf("从小到大排序: %d %d %d\n",x,y,z);
}
The above example output is:
请输入三个数字: 1 3 2 从小到大排序: 1 2 3
